Measuring and adjusting the loudness of a TV channel using bs1770gain
-
11th June 2015
-

Television loudness is the source of frustration for viewers -everywhere. Some channels are very load, others are less loud, and -ads tend to shout very high to get the attention of the viewers, and -the viewers do not like this. This fact is well known to the TV -channels. See for example the BBC white paper -"Terminology -for loudness and level dBTP, LU, and all that" from 2011 for a -summary of the problem domain. To better address the need for even -loadness, the TV channels got together several years ago to agree on a -new way to measure loudness in digital files as one step in -standardizing loudness. From this came the ITU-R standard BS.1770, -"Algorithms to -measure audio programme loudness and true-peak audio level".

- -

The ITU-R BS.1770 specification describe an algorithm to measure -loadness in LUFS (Loudness Units, referenced to Full Scale). But -having a way to measure is not enough. To get the same loudness -across TV channels, one also need to decide which value to standardize -on. For European TV channels, this was done in the EBU Recommondaton -R128, "Loudness -normalisation and permitted maximum level of audio signals", which -specifies a recommended level of -23 LUFS. In Norway, I have been -told that NRK, TV2, MTG and SBS have decided among themselves to -follow the R128 recommondation for playout from 2016-03-01.

- -

There are free software available to measure and adjust the loudness -level using the LUFS. In Debian, I am aware of a library named -libebur128 -able to measure the loudness and since yesterday morning a new binary -named bs1770gain -capable of both measuring and adjusting was uploaded and is waiting -for NEW processing. I plan to maintain the latter in Debian under the -Debian -multimedia umbrella.

- -

The free software based TV channel I am involved in, -Frikanalen, plan to follow the -R128 recommondation ourself as soon as we can adjust the software to -do so, and the bs1770gain tool seem like a good fit for that part of -the puzzle to measure loudness on new video uploaded to Frikanalen. -Personally, I plan to use bs1770gain to adjust the loudness of videos -I upload to Frikanalen on behalf of the -NUUG member organisation. The program seem to be able to measure -the LUFS value of any media file handled by ffmpeg, but I've only -successfully adjusted the LUFS value of WAV files. I suspect it -should be able to adjust it for all the formats handled by ffmpeg.

Simpler recipe on how to make a simple $7 IMSI Catcher using Debian
+
9th August 2017
+

On friday, I came across an interesting article in the Norwegian +web based ICT news magazine digi.no on +how +to collect the IMSI numbers of nearby cell phones using the cheap +DVB-T software defined radios. The article refered to instructions +and a recipe by +Keld Norman on Youtube on how to make a simple $7 IMSI Catcher, and I decided to test them out.

+ +

The instructions said to use Ubuntu, install pip using apt (to +bypass apt), use pip to install pybombs (to bypass both apt and pip), +and the ask pybombs to fetch and build everything you need from +scratch. I wanted to see if I could do the same on the most recent +Debian packages, but this did not work because pybombs tried to build +stuff that no longer build with the most recent openssl library or +some other version skew problem. While trying to get this recipe +working, I learned that the apt->pip->pybombs route was a long detour, +and the only piece of software dependency missing in Debian was the +gr-gsm package. I also found out that the lead upstream developer of +gr-gsm (the name stand for GNU Radio GSM) project already had a set of +Debian packages provided in an Ubuntu PPA repository. All I needed to +do was to dget the Debian source package and built it.

+ +

The IMSI collector is a python script listening for packages on the +loopback network device and printing to the terminal some specific GSM +packages with IMSI numbers in them. The code is fairly short and easy +to understand. The reason this work is because gr-gsm include a tool +to read GSM data from a software defined radio like a DVB-T USB stick +and other software defined radios, decode them and inject them into a +network device on your Linux machine (using the loopback device by +default). This proved to work just fine, and I've been testing the +collector for a few days now.

+ +

The updated and simpler recipe is thus to

+ +
    + +
  1. start with a Debian machine running Stretch or newer,
    2. + +
  2. build and install the gr-gsm package available from +http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/,
    3. + +
  3. clone the git repostory from https://github.com/Oros42/IMSI-catcher,
    4. + +
  4. run grgsm_livemon and adjust the frequency until the terminal +where it was started is filled with a stream of text (meaning you +found a GSM station).
    5. + +
  5. go into the IMSI-catcher directory and run 'sudo python simple_IMSI-catcher.py' to extract the IMSI numbers.
    6. + +
+ +

To make it even easier in the future to get this sniffer up and +running, I decided to package +the gr-gsm project +for Debian (WNPP +#871055), and the package was uploaded into the NEW queue today. +Luckily the gnuradio maintainer has promised to help me, as I do not +know much about gnuradio stuff yet.

+ +

I doubt this "IMSI cacher" is anywhere near as powerfull as +commercial tools like +The +Spy Phone Portable IMSI / IMEI Catcher or the +Harris +Stingray, but I hope the existance of cheap alternatives can make +more people realise how their whereabouts when carrying a cell phone +is easily tracked. Seeing the data flow on the screen, realizing that +I live close to a police station and knowing that the police is also +wearing cell phones, I wonder how hard it would be for criminals to +track the position of the police officers to discover when there are +police near by, or for foreign military forces to track the location +of the Norwegian military forces, or for anyone to track the location +of government officials...

+ +

It is worth noting that the data reported by the IMSI-catcher +script mentioned above is only a fraction of the data broadcasted on +the GSM network. It will only collect one frequency at the time, +while a typical phone will be using several frequencies, and not all +phones will be using the frequencies tracked by the grgsm_livemod +program. Also, there is a lot of radio chatter being ignored by the +simple_IMSI-catcher script, which would be collected by extending the +parser code. I wonder if gr-gsm can be set up to listen to more than +one frequency?

Hva gjør at NRK kan distribuere H.264-video uten patentavtale med MPEG LA?
-
10th June 2015
-

Helt siden jeg i 2012 fikk beskjed fra MPEG LA om at -NRK -trengte patentavtale med dem hvis de distribuerte H.264-video til -sluttbrukere, har jeg lurt på hva som gjør at NRK ikke har slik -avtale. For noen dager siden fikk jeg endelig gjort noe med min -undring, og sendte 2015-05-28 følgende epost til info (at) nrk.no med -tittel "Hva gjør at NRK kan distribuere H.264-video uten patentavtale -med MPEG LA?":

- -

-

Jeg lurer på en ting rundt NRKs bruk av H.264-video på sine -websider samt distribusjon via RiksTV og kabel-TV. Har NRK vurdert om -det er behov for en patentavtale med -MPEG LA slik det står i -programvarelisensene til blant annet Apple Final Cut Studio, Adobe -Premiere Pro, Avid og Apples Final Cut Pro X?

- -

Hvis dere har vurdert dette, hva var utfallet av en slik vurdering?

- -

Hvis dere ikke har vurdert dette, har NRK planer om å vurdere behovet -for patentavtale?

- -

I følge en artikkel på -NRK -Beta i 2012 har NRK brukt eller testet både Apple Final Cut -Studio, Adobe Premiere Pro, Avid og Apples Final Cut Pro X til bruk -for å redigere video før sending. Alle disse har bruksvilkår -understøttet av opphavsretten som sier at de kun kan brukes til å lage -filmer til personlig og ikke-kommersiell bruk - med mindre en har en -lisensavtale med MPEG LA om bruk av patenter utstedt i USA for H.264. -Se f.eks. bruksvilkårene for Avid, Adobe Premiere og Apple Final -Cut Studio og søk etter "MPEG LA".

- -

Dette får meg til å lure på om det er brudd på opphavsretten å bruke -disse verktøyene i strid med bruksvilkårene uten patentavtale med MPEG -LA. Men NRK bruker jo tilsynelatende disse verktøyene uten patentavtale -med MPEG LA.

- -

I følge forfatteren av Open Broadcast Encoder finnes det to typer -H.264-relaterte avtaler en kan få med MPEG LA. Det er én for å lage -programvare og utstyr som produserer H.264-video, og en annen for å -kringkaste video som bruker H.264. Dette forteller meg at selv om -produsentene av utstyr og programvare som NRK bruker har en slik avtale -med MPEG LA, så trenges det en egen avtale for å kringkaste video på det -formatet.

- -

I følge Ryan Rodriguez hos MPEG LA, da jeg spurte ham på epost i -juni 2012, har NRK ikke en slik avtale med MPEG LA. Han sa videre at -NRK trenger en slik avtale hvis NRK tilbyr H.264-kodet video til -sluttbrukere. Jeg sjekket listen med -organisasjoner -med avtale med MPEG LA og NRK står fortsatt ikke der.

- -

Jeg lurer dermed på hva som gjør at NRK kan bruke de overnevnte -videoredigeringsverktøyene, som tilsynelatende har krav om avtale med -MPEG LA for å kunne brukes slik NRK bruker dem, til å lage videofiler -for distribusjon uten å ha en avtale med MPEG LA om distribusjon av -H.264-video? Dette er spesielt interessant å vite for oss andre som -også vurderer å spre H.264-video etter å ha redigert dem med disse mye -brukte videoredigeringsverktøyene.

-

- -

Samme dag fikk jeg automatisk svar om at min henvendelse hadde fått -saksid 1294699. Jeg fikk deretter følgende respons fra NRK -2015-06-09:

- -

-

Hei, beklager lang svartid, men det tok litt tid å finne ut hvem som kunne -svare på dette.

- -

For selskaper som leverer h.264 til sluttbrukere på nett (f.eks -NRKs nett- tv utgaver som bruker h.264) - og som leverer slike -tjenester uten betaling fra forbrukere – er det heller ikke påkrevd -noen patentavtale.

- -

Spørsmålet er ikke kun om MPEG LA krever patentavtale eller ikke -(hvilket ikke helt besvares av pressemeldingen omtalt over, gitt at -pressemeldingen kom i 2010, to år før MPEG LA ansvarlige for -internasjonal lisensiering egen Ryan Rodriguez fortalte meg på epost -at NRK trenger en lisens.

- -

Det er uklart fra pressemeldingen hva "Internet Broadcast AVC -Video" konkret betyr, men i følge en -presentasjon -fra MPEG LA med tema "AVC PAtent Portfoli License Briefing" datert -2015-05-15 gjelder "Internet Broadcast AVC Video" kun kringkasting -på Internet som ikke tilbyr valg av enkeltinnslag ("not -title-by-title"), hvilket jo NRK gjør på sine nettsider. I tillegg -kringkaster jo NRK H.264-video også utenom Internet (RiksTV, kabel, -satelitt), hvilket helt klart ikke er dekket av vilkårene omtalt i -pressemeldingen.

- -

Spørsmålet mitt er hvordan NRK kan bruke verktøy med bruksvilkår -som krever avtale med MPEG LA for det NRK bruker dem til, når NRK ikke -har avtale med MPEG LA. Hvis jeg forsto spørsmålet riktig, så mener -NRK at dere ikke trenger avtale med MPEG LA, men uten slik avtale kan -dere vel ikke bruke hverken Apple Final Cut Studio, Adobe Premiere -Pro, Avid eller Apples Final Cut Pro X for å redigere video før -sending?

- -

Mine konkrete spørsmål var altså:

- -
    - -
  • Hvis NRK har vurdert om det er behov for en patentavtale med MPEG LA - slik det er krav om i programvarelisensene til blant annet Apple - Final Cut Studio, Adobe Premiere Pro, Avid og Apples Final Cut Pro X, - hva var utfallet av en slik vurdering? Kan jeg fÃ¥ kopi av vurderingen - hvis den er gjort skriftlig?
    • - -
  • Hvis NRK ikke har vurdert dette, har NRK planer om Ã¥ vurdere behovet - for patentavtale?
    • - -
  • Hva slags saksnummer fikk min henvendelse i NRKs offentlige - postjournal? Jeg ser at postjournalen ikke er publisert for den - aktuelle perioden ennÃ¥, sÃ¥ jeg fikk ikke sjekket selv.
    • - -
-

- -

Det hjelper å ha funnet rette vedkommende i NRK, for denne gangen -fikk jeg svar tilbake dagen etter (2015-06-10), fra Geir Børdalen i -NRK:

- -

-

Hei Petter Reinholdtsen

- -

Jeg har sjekket saken med distribusjonssjef for tv, Arild Hellgren -(som var teknologidirektør da bakkenettet ble satt opp). NRK v/ -Hellgren hadde møte med MPEG LA sammen med den europeiske -kringkastingsunionen EBU før bakkenettet for TV ble satt opp -(igangsatt høsten 2007). I dette møtet ble det avklart at NRK/EBU ikke -trengte noen patentavtale for h.264 i forbindelse med oppsett av -bakkenettet eller bruk av MPEG4 h.264 som kompresjonsalgoritme fordi -tjenesten «in full»(nor: helt) var betalt av utsendelseselskapene og -ikke av forbrukerne.

- -

http://www.nrk.no/oppdrag/digitalt-bakkenett-1.3214555

- -

Det er også klart slått fast at selskaper som leverer video basert -på MPEG4 h.264 til sluttbrukere på nett, heller ikke påkrevd noen -patentavtale – så lenge de leverer slike tjenester uten betaling fra -sluttbrukere.

- -http://www.businesswire.com/news/home/20100825006629/en/MPEG-LA%E2%80%99s-AVC-License-Charge-Royalties-Internet#.VWb2ws_774Y - -

“MPEG LA announced today that its AVC Patent Portfolio License will -continue not to charge royalties for Internet Video that is free to -end users (known as “Internet Broadcast AVC Video”) during the entire -life of this License. MPEG LA previously announced it would not charge -royalties for such video through December 31, 2015 (see -http://www.mpegla.com/Lists/MPEG%20LA%20News%20List/Attachments/226/n-10-02-02.pdf), -and today’s announcement makes clear that royalties will continue not -to be charged for such video beyond that time. Products and services -other than Internet Broadcast AVC Video continue to be -royalty-bearing.”

- -

Vi har derfor ikke noe behov for å vurdere noen patentavtale med -MPEG LA.

- -

Understreker for øvrig at NRK ikke er låst til MPEG4 – h.264 som -utsendelsesformat – og at vi har brukt og bruker flere andre -alternativer i våre tjenester. Ulike «devicer» har ofte behov for -forskjellige løsninger – og NRK har forsøkt å levere med best mulig -kvalitet /økonomi /stabilitet avhengig av -plattform. Produksjonsformater i NRK spenner for øvrig over en rekke -forskjellige formater – hvor MPEG4 bare er en av disse. Når NRK kjøper -teknisk utstyr er betaling for kodekstøtte ofte en del av -anskaffelsesprisen for denne maskinvaren (enten dette er spesialiserte -enkodere eller forskjellige typer produksjonsutstyr).

> Hei Petter Reinholdtsen

- -

Hei, og takk for raskt svar. Er min henvendelse journalført slik -at den dukker opp i NRKs postjournal?

- -

Svaret ditt var meget nyttig, og jeg forstår ut fra det du skriver -at avklaringen med MPEG LA rundt H.264-distribusjon via bakkenettet -gjelder alle TV-kanaler i Norge. Hvilke saksnummer fikk dokumenter -som ble opprettet i forbindelse med det omtalte møtet NRK v/Hellgren -og EBU hadde med MPEG LA (dvs. referater, avtaler, etc), -f.eks. dokumentet der formuleringen "in full" som du omtaler -finnes?

- -

Men det er et par ting jeg fortsatt ikke forstår. Det ene er -hvorfor NRKs forståelse av hva "Internet Broadcast AVC Video" dekker -ser ut til å avvike fra det som presenteres i -lysark -fra MPEG LA i mai, der MPEG LA på lysark med overskriften -"AVC/H.264 License Terms Participation Fees" og undertittel "Where -remuneration is from other sources" skriver "Internet Broadcast AVC -Video (not title-by-title, not subscription) – no royalty for life of -the AVC Patent Portfolio License".

- -

Her leser jeg MPEG LA dithen at det kun er kringkasting uten -abonnement via Internet som er dekket at vilkårne omtalt i -pressemeldingen, mens jeg forstår deg dithen at NRK mener NRKs -nettsider som også har enkeltfilmer og innslag (som jeg forstår dekket -av formuleringen "title-by-title") dekkes av "Internet Broadcast AVC -Video" fra MPEG LA. Hva baserer dere denne tolkningen på? Jeg har -ikke sett noe skriftlig fra MPEG LA som støtter NRKs tolkning, og -lurer på om dere har andre kilder enn den pressemeldingen fra 5 år -tilbake, der NRKS forståelse av hva "Internet Broadcast AVC Video" -dekker er beskrevet?

- -

Det andre er at eposten din ikke nevnte spørsmålet mitt om -bruksvilkårene til videoredigeringsverktøyene som NRK bruker. Disse -har som tidligere nevnt krav om at de kun skal brukes til private og -ikke-kommersielle formål med mindre en har avtale med MPEG LA, og uten -avtale med MPEG LA kan det jo virke som om NRK bruker verktøyene i -strid med bruksvilkårene. Hva gjør at disse bruksvilkårene ikke -gjelder for NRK?

-

- -

Noen minutter senere får jeg foreløpig siste svar i -føljetongen:

- -

-

Hei igjen

- -

Vårt dokumentarkiv har fått en kopi (journalføringsnr kan jeg -dessverre ikke gi deg).

- -

> Svaret ditt var meget nyttig, og jeg forstår ut fra det du -
> skriver at avklaringen med MPEG LA rundt H.264-distribusjon via -
> bakkenettet gjelder alle TV-kanaler i Norge.

- -

Svar: Kan ikke svare for andre enn for NRK/EBU - og for bakkenettet -i Norge er det kun NRK som er et lisensbasert selskap. Kan ikke gi noe -svar på saksnr på dokumenter eller ytterligere informasjon da jeg selv -ikke var del i dette.

- -

> Men det er et par ting jeg fortsatt ikke forstår. ...

- -

Svar: Kan ikke gå ytterligere inn i dette fra min side og mitt -fagfelt som er produksjon/publisering og systemstrukturene bak -disse. For øvrig ligger det etter vår formening ingen begrensninger -for NRK i mulighetene til publisering mht til kodek i -produksjonssystemer. Som tidligere skrevet mener vi at NRK ikke -trenger noen avtale med MPEG LA og støtter oss til det vi allerede har -kommunisert i forrige epost.

- -

Mvh -
Geir Børdalen

-

- -

Det syntes vanskelig å komme videre når NRK ikke ønsker å gå inn i -problemstillingen rundt bruksvilkårene til videoredigeringsverktøyene -NRK bruker, så jeg sendte takk for svarene og avsluttet utvekslingen -så langt:

- -

-

Tusen takk for rask respons, og oppklarende forklaring om hvordan -NRK tenker rundt MPEG LA.

- -

Jeg vil høre med NRK-arkivet for å se om de kan spore opp de -omtalte dokumentene. Jeg setter pris på om du kan dele titler, dato -eller annen informasjon som kan gjøre det enklere for arkivet å finne -dem.

- -

Når det gjelder hvordan bruksvilkårene til -videoredigeringsverktøyene skal tolkes, så skal jeg høre med MPEG LA -og produsentene av verktøyene for å forsøke å få klarhet i hva de -mener er rikgig rettstilstand.

-

- -

Jeg ble litt klokere, men fortsatt er det uklart for meg hva som er -grunnlaget til NRK for å se bort fra bruksvilkår i -videoredigeringsprogramvare som krever MPEG LA-avtale til alt annet -enn privat og ikke-kommersiell bruk.

Blir det virkelig krav om fingeravtrykk i nasjonale ID-kort?
-
12th May 2015

Noen finner det vanskelig å tro at Stortinget faktisk har vedtatt å -kreve at alle norske borgerne må avgi fingeravtrykk til politiet for å -fungere i samfunnet. Jeg er blitt spurt hva som er grunnlaget for -min -påstand i forrige bloggpost om at det nå blir krav om å avgi -fingeravtrykk til politiet for å fungere som borger i Norge. De som -spør klarer ikke lese det ut fra det som er vedtatt. Her er en liten -oppsummering om hva jeg baserer det på. Det sies ikke direkte i -hverken proposisjon, innstilling eller vedtak, men fremgår når en ser -på indirekte formuleringer.

I -stortingsproposisjon -66, avsnitt 6.3.5 (Avgivelse av biometriske personopplysninger) -står det

+

«Rapporten ser ikke på informasjonssikkerhet knyttet til personlig integritet»
+
27th June 2017
+

Jeg kom over teksten +«Killing +car privacy by federal mandate» av Leonid Reyzin på Freedom to +Tinker i dag, og det gleder meg å se en god gjennomgang om hvorfor det +er et urimelig inngrep i privatsfæren å la alle biler kringkaste sin +posisjon og bevegelse via radio. Det omtalte forslaget basert på +Dedicated Short Range Communication (DSRC) kalles Basic Safety Message +(BSM) i USA og Cooperative Awareness Message (CAM) i Europa, og det +norske Vegvesenet er en av de som ser ut til å kunne tenke seg å +pålegge alle biler å fjerne nok en bit av innbyggernes privatsfære. +Anbefaler alle å lese det som står der. + +

Mens jeg tittet litt på DSRC på biler i Norge kom jeg over et sitat +jeg synes er illustrativt for hvordan det offentlige Norge håndterer +problemstillinger rundt innbyggernes privatsfære i SINTEF-rapporten +«Informasjonssikkerhet +i AutoPASS-brikker» av Trond Foss:

- -

Departementet foreslår at både ansiktsfoto og fingeravtrykk skal - kunne opptas og lagres som identifikasjonsdata i de nasjonale - ID-kortene, på samme måte som i passene. Lovforslaget er derfor - utformet i tråd med passloven § 6 annet ledd, som fastslår at det - til bruk for senere verifisering eller kontroll av passinnehaverens - identitet kan innhentes og lagres i passet biometrisk - personinformasjon i form av ansiktsfoto og fingeravtrykk (to - fingre). Dagens ordning med lagring av ansiktsfoto og fingeravtrykk - i et kontaktløst smartkort i passet er basert på internasjonale - standarder. Fingeravtrykkene i nasjonalt ID-kort vil bli beskyttet - på samme måte som fingeravtrykkene i passene.

- -

[...]

- -

For norske forhold understreker departementet at innføring av - nasjonale ID-kort sammen med innføring av nye systemer for sikrere - utstedelse og kontroll av pass og relaterte dokumenter gir mulighet - til å utforme ordningen slik at den best mulig møter utfordringene - forbundet med identitetskriminalitet. Det tilsier at fingeravtrykk - opptas og lagres i alle nasjonale ID-kort.

+«Rapporten ser ikke på informasjonssikkerhet knyttet til personlig + integritet.»

-

Departementet sier altså at sin anbefaling er at fingeravtrykk skal -opptas og lagres i alle nasjonale ID-kort. Det skrives som om det -blir valgfritt, på samme måten som det skrives passloven, der det i -loven sier at det kan -«innhentes -og lagres i passet biometrisk personinformasjon i form av ansiktsfoto -og fingeravtrykk (to fingre)». Men på tross av bruken av «kan» i -passloven er det innført krav om å avgi fingeravtrykk for å få et pass -i Norge. Proposisjonen sier i tillegg i del 1 (Proposisjonens -hovedinnhold) at ID-kortene skal være like pålitelig som pass og ha -samme sikkerhetsnivå som pass. Departementet foreslår altså at -ID-kortene skal gis etter samme regler som for pass.

- -

Formuleringene fra hovedinnholdet i proposisjonen er videreført i -innstillingen -fra stortingskomiteen, der det konkret står «De foreslåtte reglene -vil gi befolkningen tilbud om et offentlig utstedt identitetsbevis som -vil være like pålitelig som passet, og mer praktisk å bruke som -legitimasjon» og «Det nasjonale ID-kortet skal også holde samme -sikkerhetsnivå som passet». Komiteen har altså ingen kommentarer -eller innsigelser til dette forslaget, og gjorde i debatten da saken -ble vedtatt det klart at dette var en god sak og at en enstemmig -komité var glad for resultatet. Stortinget har dermed stilt seg helt -og fullt bak departementets forslag.

- -

For meg er det åpenbart når en leser proposisjonen at «like -pålitelig» og «samme sikkerhetsnivå» vil bli tolket av departementet -som «med samme biometrisk informasjon som i passene», og departementet -forklarer i tillegg i proposisjonen at de har tenkt at -fingeravtrykkene «vil bli beskyttet på samme måte som fingeravtrykkene -i passene». Jeg ser det dermed som åpenbart at den samme -tvangsinnhentingen av fingeravtrykk som gjelder for pass vil bli -viderført til de nasjonale ID-kortene.

Det eneste som kan endre dette er massive protester fra -befolkningen på at folk som ikke er mistenkt for noe kriminelt skal -tvinges til å gi fingeravtrykket til politiet for å f.eks. kunne få -bankkonto eller stemme ved valg. Det kunne få departementet til å -snu. Det tror jeg ikke vil skje.

Så enkelt kan det tydeligvis gjøres når en vurderer +informasjonssikkerheten.

Det er jo sjelden det får reaksjoner. Historien om +reaksjonene på Helse Sør-Østs tjenesteutsetting er jo sørgelig nok et +unntak og toppen av isfjellet, desverre.

Norwegian citizens now required by law to give their fingerprint to the police
-
10th May 2015
-

5 days ago, the Norwegian Parliament decided, unanimously, that all -citizens of Norway, no matter if they are suspected of something -criminal or not, are -required to -give fingerprints to the police (vote details from Holder de -ord). The law make it sound like it will be optional, but in a few -years there will be no option any more. The ID will be required to -vote, to get a bank account, a bank card, to change address on the -post office, to receive an electronic ID or to get a drivers license -and many other tasks required to function in Norway. The banks plan -to stop providing their own ID on the bank cards when this new -national ID is introduced, and the national road authorities plan to -change the drivers license to no longer be usable as identity cards. -In effect, to function as a citizen in Norway a national ID card will -be required, and to get it one need to provide the fingerprints to -the police.

- -

In addition to handing the fingerprint to the police (which -promised to not make a copy of the fingerprint image at that point in -time, but say nothing about doing it later), a picture of the -fingerprint will be stored on the RFID chip, along with a picture of -the face and other information about the person. Some of the -information will be encrypted, but the encryption will be the same -system as currently used in the passports. The codes to decrypt will -be available to a lot of government offices and their suppliers around -the globe, but for those that do not know anyone in those circles it -is good to know that -the -encryption is already broken. And they -can -be read from 70 meters away. This can be mitigated a bit by -keeping it in a Faraday cage (metal box or metal wire container), but -one will be required to take it out of there often enough to expose -ones private and personal information to a lot of people that have no -business getting access to that information.

- -

The new Norwegian national IDs are a vehicle for identity theft, -and I feel sorry for us all having politicians accepting such invasion -of privacy without any objections. So are the Norwegian passports, -but it has been possible to function in Norway without those so far. -That option is going away with the passing of the new law. In this, I -envy the Germans, because for them it is optional how much biometric -information is stored in their national ID.

- -

And if forced collection of fingerprints was not bad enough, the -information collected in the national ID card register can be handed -over to foreign intelligence services and police authorities, "when -extradition is not considered disproportionate".

It is pleasing to see that the work we put down in publishing new +editions of the classic Free +Culture book by the founder of the Creative Commons movement, +Lawrence Lessig, is still being appreciated.

What would it cost to store all phone calls in Norway?
-
1st May 2015
-

Many years ago, a friend of mine calculated how much it would cost -to store the sound of all phone calls in Norway, and came up with the -cost of around 20 million NOK (2.4 mill EUR) for all the calls in a -year. I got curious and wondered what the same calculation would look -like today. To do so one need an idea of how much data storage is -needed for each minute of sound, how many minutes all the calls in -Norway sums up to, and the cost of data storage.

- -

The 2005 numbers are from -digi.no, -the 2012 numbers are from -a -NKOM report, and I got the 2013 numbers after asking NKOM via -email. I was told the numbers for 2014 will be presented May 20th, -and decided not to wait for those, as I doubt they will be very -different from the numbers from 2013.

- -

The amount of data storage per minute sound depend on the wanted -quality, and for phone calls it is generally believed that 8 Kbit/s is -enough. See for example a -summary -on voice quality from Cisco for some alternatives. 8 Kbit/s is 60 -Kbytes/min, and this can be multiplied with the number of call minutes -to get the storage requirements.

- -

Storage prices varies a lot, depending on speed, backup strategies, -availability requirements etc. But a simple way to calculate can be -to use the price of a TiB-disk (around 1000 NOK / 120 EUR) and double -it to take space, power and redundancy into account. It could be much -higher with high speed and good redundancy requirements.

- -

But back to the question, What would it cost to store all phone -calls in Norway? Not much. Here is a small table showing the -estimated cost, which is within the budget constraint of most medium -and large organisations:

I am very happy to report that the +Nikita Noark 5 +core project tagged its second release today. The free software +solution is an implementation of the Norwegian archive standard Noark +5 used by government offices in Norway. These were the changes in +version 0.1.1 since version 0.1.0 (from NEWS.md): + +

    + +
  • Continued work on the angularjs GUI, including document upload.
    • +
  • Implemented correspondencepartPerson, correspondencepartUnit and + correspondencepartInternal
    • +
  • Applied for coverity coverage and started submitting code on + regualr basis.
    • +
  • Started fixing bugs reported by coverity
    • +
  • Corrected and completed HATEOAS links to make sure entire API is + available via URLs in _links.
    • +
  • Corrected all relation URLs to use trailing slash.
    • +
  • Add initial support for storing data in ElasticSearch.
    • +
  • Now able to receive and store uploaded files in the archive.
    • +
  • Changed JSON output for object lists to have relations in _links.
    • +
  • Improve JSON output for empty object lists.
    • +
  • Now uses correct MIME type application/vnd.noark5-v4+json.
    • +
  • Added support for docker container images.
    • +
  • Added simple API browser implemented in JavaScript/Angular.
    • +
  • Started on archive client implemented in JavaScript/Angular.
    • +
  • Started on prototype to show the public mail journal.
    • +
  • Improved performance by disabling Sprint FileWatcher.
    • +
  • Added support for 'arkivskaper', 'saksmappe' and 'journalpost'.
    • +
  • Added support for some metadata codelists.
    • +
  • Added support for Cross-origin resource sharing (CORS).
    • +
  • Changed login method from Basic Auth to JSON Web Token (RFC 7519) + style.
    • +
  • Added support for GET-ing ny-* URLs.

This is the cost of buying the storage. Maintenance need to be -taken into account too, but calculating that is left as an exercise -for the reader. But it is obvious to me from those numbers that -recording the sound of all phone calls in Norway is not going to be -stopped because it is too expensive.

Idea for storing trusted timestamps in a Noark 5 archive

+      
 7th June 2017

+      
This is a copy of
+an
+email I posted to the nikita-noark mailing list.  Please follow up
+there if you would like to discuss this topic.  The background is that
+we are making a free software archive system based on the Norwegian
+Noark
+5 standard for government archives.

+
+
I've been wondering a bit lately how trusted timestamps could be
+stored in Noark 5.
+Trusted
+timestamps can be used to verify that some information
+(document/file/checksum/metadata) have not been changed since a
+specific time in the past.  This is useful to verify the integrity of
+the documents in the archive.

+
+
Then it occured to me, perhaps the trusted timestamps could be
+stored as dokument variants (ie dokumentobjekt referered to from
+dokumentbeskrivelse) with the filename set to the hash it is
+stamping?

+
+
Given a "dokumentbeskrivelse" with an associated "dokumentobjekt",
+a new dokumentobjekt is associated with "dokumentbeskrivelse" with the
+same attributes as the stamped dokumentobjekt except these
+attributes:

-
-== About Debian Edu / Skolelinux ==
-
-Debian Edu, also known as Skolelinux, is a Linux distribution based on
-Debian providing an out-of-the box environment of a completely
-configured school network. Directly after installation a school server
-running all services needed for a school network is set up just
-waiting for users and machines being added via GOsa², a comfortable
-Web-UI. A netbooting environment is prepared using PXE, so after
-initial installation of the main server from CD or USB stick all other
-machines can be installed via the network. The provided school server
-provides LDAP database and Kerberos authentication service,
-centralized home directories, DHCP server, web proxy and many other
-services.  The desktop contains more than 60 educational software
-packages and more are available from the Debian archive, and schools
-can choose between KDE, GNOME, LXDE, Xfce and MATE desktop
-environment.

-== About Debian ==
+
    
 
-The Debian Project was founded in 1993 by Ian Murdock to be a truly
-free community project. Since then the project has grown to be one of
-the largest and most influential open source projects. Thousands of
-volunteers from all over the world work together to create and
-maintain Debian software. Available in 70 languages, and supporting a
-huge range of computer types, Debian calls itself the universal
-operating system.

  • format -> "RFC3161"
+
  • mimeType -> "application/timestamp-reply"
+
  • formatDetaljer -> "<source URL for timestamp service>"
+
  • filenavn -> "<sjekksum>.tsr"
 
-== Thanks ==

-Thanks to everyone making Debian and Debian Edu / Skolelinux happen!
-You rock.
-
+

This assume a service following +IETF RFC 3161 is +used, which specifiy the given MIME type for replies and the .tsr file +ending for the content of such trusted timestamp. As far as I can +tell from the Noark 5 specifications, it is OK to have several +variants/renderings of a dokument attached to a given +dokumentbeskrivelse objekt. It might be stretching it a bit to make +some of these variants represent crypto-signatures useful for +verifying the document integrity instead of representing the dokument +itself.

+ +

Using the source of the service in formatDetaljer allow several +timestamping services to be used. This is useful to spread the risk +of key compromise over several organisations. It would only be a +problem to trust the timestamps if all of the organisations are +compromised.

+ +

The following oneliner on Linux can be used to generate the tsr +file. $input is the path to the file to checksum, and $sha256 is the +SHA-256 checksum of the file (ie the ".tsr" value mentioned +above).

+ +

+openssl ts -query -data "$inputfile" -cert -sha256 -no_nonce \
+  | curl -s -H "Content-Type: application/timestamp-query" \
+      --data-binary "@-" http://zeitstempel.dfn.de > $sha256.tsr
+

+ +

To verify the timestamp, you first need to download the public key +of the trusted timestamp service, for example using this command:

+ +

+wget -O ca-cert.txt \
+  https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
+

+ +

Note, the public key should be stored alongside the timestamps in +the archive to make sure it is also available 100 years from now. It +is probably a good idea to standardise how and were to store such +public keys, to make it easier to find for those trying to verify +documents 100 or 1000 years from now. :)

+ +

The verification itself is a simple openssl command:

+ +

+openssl ts -verify -data $inputfile -in $sha256.tsr \
+  -CAfile ca-cert.txt -text
+

+ +

Is there any reason this approach would not work? Is it somehow against +the Noark 5 specification?

Debian Edu interview: Shirish Agarwal
-
15th April 2015
-

It was a surprise to me to learn that project to create a complete -computer system for schools I've involved in, -Debian Edu / Skolelinux, was -being used in India. But apparently it is, and I managed to get an -interview with one of the friends of the project there, Shirish -Agarwal.

- -

Who are you, and how do you spend your days?

- -

My name is Shirish Agarwal. Based out of the educational and -historical city of Pune, from the western state of Maharashtra, India. -My bread comes from giving training, giving policy tips, -installations on free software to mom and pop shops in different -fields from Desktop publishing to retail shops as well as work with -few software start-ups as well.

- -

How did you get in contact with the Skolelinux / Debian Edu -project?

- -

It started innocently enough. I have been using Debian for a few -years and in one local minidebconf / debutsav I was asked if there was -anything for schools or education. I had worked / played with free -educational softwares such as Gcompris and Stellarium for my many -nieces and nephews so researched and found Debian Edu or Skolelinux as -it was known then. Since then I have started using the various -education meta-packages provided by the project.

- -

What do you see as the advantages of Skolelinux / Debian -Edu?

- -

It's closest I have seen where a package full of educational -software are packed, which are free and open (both literally and -figuratively). Even if I take the simplest software which is -gcompris, the number of activities therein are amazing. Another one of -the softwares that I have liked for a long time is stellarium. Even -pysycache is cool except for couple of issues I encountered -#781841 and -#781842.

- -

I prefer software installed on the system over web based solutions, -as a web site can disappear any time but the software on disk has the -possibility of a larger life span. Of course with both it's more a -question if it has enough users who make it fun or sustainable or both -for the developer per-se.

- -

What do you see as the disadvantages of Skolelinux / Debian -Edu?

- -

I do see that the Debian Edu team seems to be short-handed and I -think more efforts should be made to make it popular and ask and take -help from people and the larger community wherever possible.

- -

I don't see any disadvantage to use Skolelinux apart from the fact -that most apps. are generic which is good or bad how you see it. -However, saying that I do acknowledge the fact that the canvas is -pretty big and there are lot of interesting ideas that could be done -but for reasons not known not done or if done I don't know about them. -Let me share some of the ideas (these are more upstream based but -still) I have had for a long time :

- -

1. Classical maths question of two trains in opposing directions -each running @x kmph/mph at y distance, when they will meet and how -far would each travel and similar questions like these. - -

The computer is a fantastic system where questions like these can -be drawn, animated and the methodology and answers teased out in -interactive manner. While sites such as the -Ask -Dr. Math FAQ on The Two Trains problem (as an example or point of -inspiration) can be used there is lot more that can be done. I dunno -if there is a free software which does something like this. The idea -being a blend of objects + animation + interaction which does -this. The whole interaction could be gamified with points or sounds or -colourful celebration whenever the user gets even part of the question -or/and methodology right. That would help reinforce good behaviour. -This understanding could be used to share/showcase everything from how -the first wheel came to be, to evolution to how astronomy started, -psychics and everything in-between.

- -

One specific idea in the train part was having the Linux mascot on -one train and the BSD or GNU mascot on the other train and they -meeting somewhere in-between. Characters from blender movies could -also be used.

- -

2. Loads of crossword-puzzles with reference to subjects: We have -enormous data sets in Wikipedia and Wikitionary. I don't think it -should be a big job to design crossword puzzles. Using categories and -sub-categories it should be doable to have Q&A single word answers -from the existing data-sets. What would make it easy or hard could be -the length of the word + existence of many or few vowels depending on -the user's input.

- -

3. Jigsaw puzzles - We already have a great software called -palapeli with number of slicers making it pretty interesting. What -needs to be done is to download large number of public domain and -copyleft images, tease and use IPTC tags to categorise them into -nature, history etc. and let it loose. This could turn to be really -huge collection of images. One source could be taken from -commons.wikimedia.org, others could be huge collection of royalty-free -stock photos. Potential is immense.

- -

Apart from this, free software suffers in two directions, we lag -both in development (of using new features per-se) and maintenance a -lot. This is more so in educational software as these applications -need to be timely and the opportunity cost of missing deadlines is -immense. If we are able to solve issues of funding for development and -maintenance of such software I don't see any big difficulties. I know -of few start-ups in and around India who would love to develop and -maintain such software if funding issues could be solved.

- -

Which free software do you use daily?

- -

That would be huge list. Some of the softwares are obviously apt, -aptitude, debdelta, leafpad, the shell of course (zsh nowadays), -quassel for IRC. In games I use shisen-sho while card-games are evenly -between kpat and Aiselriot. In desktops it's a tie between -gnome-flashback and mate.

- -

Which strategy do you believe is the right one to use to -get schools to use free software?

- -

I think it should first start with using specific FOSS apps. in -whatever environment they are. If it's MS-Windows or Mac so be it. -Once they are habitual with the apps. and there is buy-in from the -school management then it could be installed anywhere. Most of the -people now understand the concept of a repository because of the -various online stores so it isn't hard to convince on that front.

- -

What is harder is having enough people with technical skills and -passion to service them. If you get buy-in from one or two teachers -then ideas like above could also be asked to be done as a project as -well.

- -

I think where we fall short more than anything is in marketing. For -instance, Debian has this whole range of fonts in its archive but -there isn't even a page where all those different fonts in the La -Ipsum format could be tried out for newcomers.

One of the issues faced constantly in installations is with updates -and upgrades. People have this myth that each update and upgrade -means the user interface will / has to change. I have seen this -innumerable times. That perhaps is one of the reasons which browsers -like Iceweasel / Firefox change user interfaces so much, not because -it might be needed or be functional but because people believe that -changed user interfaces are better. This, can easily be pointed with -the user interfaces changed with almost every MS-Windows and Mac OS -releases.

NÃ¥r nynorskoversettelsen svikter til eksamen...
+
3rd June 2017
+

Aftenposten +melder i dag om feil i eksamensoppgavene for eksamen i politikk og +menneskerettigheter, der teksten i bokmåls og nynorskutgaven ikke var +like. Oppgaveteksten er gjengitt i artikkelen, og jeg ble nysgjerring +på om den fri oversetterløsningen +Apertium ville gjort en bedre +jobb enn Utdanningsdirektoratet. Det kan se slik ut.

+ +

Her er bokmålsoppgaven fra eksamenen:

+ +
+

Drøft utfordringene knyttet til nasjonalstatenes og andre aktørers +rolle og muligheter til å håndtere internasjonale utfordringer, som +for eksempel flykningekrisen.

+ +

Vedlegge er eksempler på tekster som kan gi relevante perspektiver +på temaet:

    +
  1. Flykningeregnskapet 2016, UNHCR og IDMC +
  2. «Grenseløst Europa for fall» A-Magasinet, 26. november 2015 +

  • Most of the teachers are very territorial about their subjects - and they do not want you to teach anything out of the - portion/syllabus given.
    • - -
  • They want any activity on the system in accordance to whatever - is in the syllabus.
    • - -
  • There are huge barriers both with the English language and at - times with objects or whatever. An example, let's say in gcompris - you have objects falling down and you have to name them and let's - say the falling object is a hat or a fedora hat, this would not be - as recognizable as say a - Puneri - Pagdi so there is need to inject local objects, words wherever - possible. Especially for word-games there are so many hindi words - which have become part of english vocabulary (for instance in - parley), those could be made into a hinglish collection or - something but that is something for upstream to do.
    • +

    Dette oversetter Apertium slik:

    +
    +

    Drøft utfordringane knytte til nasjonalstatane sine og rolla til +andre aktørar og høve til å handtera internasjonale utfordringar, som +til dømes *flykningekrisen.

    + +

    Vedleggja er døme på tekster som kan gje relevante perspektiv på +temaet:

    + +
      +
    1. *Flykningeregnskapet 2016, *UNHCR og *IDMC
      2. +
    2. «*Grenseløst Europa for fall» A-Magasinet, 26. november 2015
    + +
    + +

    Ord som ikke ble forstått er markert med stjerne (*), og trenger +ekstra språksjekk. Men ingen ord er forsvunnet, slik det var i +oppgaven elevene fikk presentert på eksamen. Jeg mistenker dog at +"andre aktørers rolle og muligheter til ..." burde vært oversatt til +"rolla til andre aktørar og deira høve til ..." eller noe slikt, men +det er kanskje flisespikking. Det understreker vel bare at det alltid +trengs korrekturlesning etter automatisk oversettelse.

    Epost inn som arkivformat i Riksarkivarens forskrift?
    +
    27th April 2017
    +

    I disse dager, med frist 1. mai, har Riksarkivaren ute en høring på +sin forskrift. Som en kan se er det ikke mye tid igjen før fristen +som går ut på søndag. Denne forskriften er det som lister opp hvilke +formater det er greit å arkivere i +Noark +5-løsninger i Norge.

    + +

    Jeg fant høringsdokumentene hos +Norsk +Arkivråd etter å ha blitt tipset på epostlisten til +fri +programvareprosjektet Nikita Noark5-Core, som lager et Noark 5 +Tjenestegresesnitt. Jeg er involvert i Nikita-prosjektet og takket +være min interesse for tjenestegrensesnittsprosjektet har jeg lest en +god del Noark 5-relaterte dokumenter, og til min overraskelse oppdaget +at standard epost ikke er på listen over godkjente formater som kan +arkiveres. Høringen med frist søndag er en glimrende mulighet til å +forsøke å gjøre noe med det. Jeg holder på med +egen +høringsuttalelse, og lurer på om andre er interessert i å støtte +forslaget om å tillate arkivering av epost som epost i arkivet.

    + +

    Er du igang med å skrive egen høringsuttalelse allerede? I så fall +kan du jo vurdere å ta med en formulering om epost-lagring. Jeg tror +ikke det trengs så mye. Her et kort forslag til tekst:

    + +

    + +

    Viser til høring sendt ut 2017-02-17 (Riksarkivarens referanse + 2016/9840 HELHJO), og tillater oss å sende inn noen innspill om + revisjon av Forskrift om utfyllende tekniske og arkivfaglige + bestemmelser om behandling av offentlige arkiver (Riksarkivarens + forskrift).

    + +

    Svært mye av vår kommuikasjon foregår i dag på e-post.  Vi + foreslår derfor at Internett-e-post, slik det er beskrevet i IETF + RFC 5322, + https://tools.ietf.org/html/rfc5322. bør + inn som godkjent dokumentformat.  Vi foreslår at forskriftens + oversikt over godkjente dokumentformater ved innlevering i § 5-16 + endres til å ta med Internett-e-post.

    + +

    + +

    Som del av arbeidet med tjenestegrensesnitt har vi testet hvordan +epost kan lagres i en Noark 5-struktur, og holder på å skrive et +forslag om hvordan dette kan gjøres som vil bli sendt over til +arkivverket så snart det er ferdig. De som er interesserte kan +følge +fremdriften på web.

    + +

    Oppdatering 2017-04-28: I dag ble høringuttalelsen jeg skrev + sendt + inn av foreningen NUUG.

    Proof reading the Norwegian translation of Free Culture by Lessig

    Offentlig elektronisk postjournal blokkerer tilgang for utvalgte webklienter
    +
    20th April 2017
    +

    Jeg oppdaget i dag at nettstedet som +publiserer offentlige postjournaler fra statlige etater, OEP, har +begynt å blokkerer enkelte typer webklienter fra å få tilgang. Vet +ikke hvor mange det gjelder, men det gjelder i hvert fall libwww-perl +og curl. For å teste selv, kjør følgende:

    + +
    +% curl -v -s https://www.oep.no/pub/report.xhtml?reportId=3 2>&1 |grep '< HTTP'
+< HTTP/1.1 404 Not Found
+% curl -v -s --header 'User-Agent:Opera/12.0' https://www.oep.no/pub/report.xhtml?reportId=3 2>&1 |grep '< HTTP'
+< HTTP/1.1 200 OK
+%
+
    + +

    Her kan en se at tjenesten gir «404 Not Found» for curl i +standardoppsettet, mens den gir «200 OK» hvis curl hevder å være Opera +versjon 12.0. Offentlig elektronisk postjournal startet blokkeringen +2017-03-02.

    + +

    Blokkeringen vil gjøre det litt vanskeligere å maskinelt hente +informasjon fra oep.no. Kan blokkeringen være gjort for å hindre +automatisert innsamling av informasjon fra OEP, slik Pressens +Offentlighetsutvalg gjorde for å dokumentere hvordan departementene +hindrer innsyn i +rapporten +«Slik hindrer departementer innsyn» som ble publiserte i januar +2017. Det virker usannsynlig, da det jo er trivielt å bytte +User-Agent til noe nytt.

    + +

    Finnes det juridisk grunnlag for det offentlige å diskriminere +webklienter slik det gjøres her? Der tilgang gis eller ikke alt etter +hva klienten sier at den heter? Da OEP eies av DIFI og driftes av +Basefarm, finnes det kanskje noen dokumenter sendt mellom disse to +aktørene man kan be om innsyn i for å forstå hva som har skjedd. Men +postjournalen +til DIFI viser kun to dokumenter det siste året mellom DIFI og +Basefarm. +Mimes brønn neste, +tenker jeg.

    Frikanalen, Norwegian TV channel for technical topics

    9th March 2015

    The Norwegian Unix User Group, -where I am a member, and where people interested in free software, -open standards and UNIX like operating systems like Linux and the BSDs -come together, record our monthly technical presentations on video. -The purpose is to document the talks and spread them to a wider -audience. For this, the the Norwegian nationwide open channel -Frikanalen is a useful venue. -Since a few days ago, when I figured out the -REST API to program the -channel time schedule, -the channel has been filled with NUUG talks, related recordings and -some Creative Commons licensed TED talks (from archive.org). I fill -all "leftover bits" on the channel with content from NUUG, which at -the moment is almost 17 of 24 hours every day.

    - -

    The list of NUUG videos -uploaded so far -include things like a -one hour talk by John -Perry Barlow when he visited Oslo, a presentation of -Haiku, the BeOS -re-implementation, the -history of FiksGataMi, -the Norwegian version of FixMyStreet, the good old -Warriors of the net -video and many others.

    - -

    We have a large backlog of NUUG talks not yet uploaded to -Frikanalen, and plan to upload every useful bit to the channel to -spread the word there. I also hope to find useful recordings from the -Chaos Computer Club and Debian conferences and spread them on the -channel as well. But this require locating the videos and their meta -information (title, description, license, etc), and preparing the -recordings for broadcast, and I have not yet had the spare time to -focus on this. Perhaps you want to help. Please join us on IRC, -#nuug on irc.freenode.net -if you want to help make this happen.

    But as I said, already the channel is already almost exclusively -filled with technical topics, and if you want to learn something new -today, check out the Ogg Theora -web stream or use one of the other ways to get access to the -channel.

    Free software archive system Nikita now able to store documents
    +
    19th March 2017
    +

    The Nikita +Noark 5 core project is implementing the Norwegian standard for +keeping an electronic archive of government documents. +The +Noark 5 standard document the requirement for data systems used by +the archives in the Norwegian government, and the Noark 5 web interface +specification document a REST web service for storing, searching and +retrieving documents and metadata in such archive. I've been involved +in the project since a few weeks before Christmas, when the Norwegian +Unix User Group +announced +it supported the project. I believe this is an important project, +and hope it can make it possible for the government archives in the +future to use free software to keep the archives we citizens depend +on. But as I do not hold such archive myself, personally my first use +case is to store and analyse public mail journal metadata published +from the government. I find it useful to have a clear use case in +mind when developing, to make sure the system scratches one of my +itches.

    + +

    If you would like to help make sure there is a free software +alternatives for the archives, please join our IRC channel +(#nikita on +irc.freenode.net) and +the +project mailing list.

    + +

    When I got involved, the web service could store metadata about +documents. But a few weeks ago, a new milestone was reached when it +became possible to store full text documents too. Yesterday, I +completed an implementation of a command line tool +archive-pdf to upload a PDF file to the archive using this +API. The tool is very simple at the moment, and find existing +fonds, series and +files while asking the user to select which one to use if more than +one exist. Once a file is identified, the PDF is associated with the +file and uploaded, using the title extracted from the PDF itself. The +process is fairly similar to visiting the archive, opening a cabinet, +locating a file and storing a piece of paper in the archive. Here is +a test run directly after populating the database with test data using +our API tester:

    + +

    +~/src//noark5-tester$ ./archive-pdf mangelmelding/mangler.pdf
+using arkiv: Title of the test fonds created 2017-03-18T23:49:32.103446
+using arkivdel: Title of the test series created 2017-03-18T23:49:32.103446
+
+ 0 - Title of the test case file created 2017-03-18T23:49:32.103446
+ 1 - Title of the test file created 2017-03-18T23:49:32.103446
+Select which mappe you want (or search term): 0
+Uploading mangelmelding/mangler.pdf
+  PDF title: Mangler i spesifikasjonsdokumentet for NOARK 5 Tjenestegrensesnitt
+  File 2017/1: Title of the test case file created 2017-03-18T23:49:32.103446
+~/src//noark5-tester$
+

    + +

    You can see here how the fonds (arkiv) and serie (arkivdel) only had +one option, while the user need to choose which file (mappe) to use +among the two created by the API tester. The archive-pdf +tool can be found in the git repository for the API tester.

    + +

    In the project, I have been mostly working on +the API +tester so far, while getting to know the code base. The API +tester currently use +the HATEOAS links +to traverse the entire exposed service API and verify that the exposed +operations and objects match the specification, as well as trying to +create objects holding metadata and uploading a simple XML file to +store. The tester has proved very useful for finding flaws in our +implementation, as well as flaws in the reference site and the +specification.

    + +

    The test document I uploaded is a summary of all the specification +defects we have collected so far while implementing the web service. +There are several unclear and conflicting parts of the specification, +and we have +started +writing down the questions we get from implementing it. We use a +format inspired by how The +Austin Group collect defect reports for the POSIX standard with +their +instructions for the MANTIS defect tracker system, in lack of an official way to structure defect reports for Noark 5 (our first submitted defect report was a request for a procedure for submitting defect reports :). + +

    The Nikita project is implemented using Java and Spring, and is +fairly easy to get up and running using Docker containers for those +that want to test the current code base. The API tester is +implemented in Python.
