A program should be able to open its own files on Linux

5th June 2016

Many years ago, when koffice was fresh and with few users, I -decided to test its presentation tool when making the slides for a -talk I was giving for NUUG on Japhar, a free Java virtual machine. I -wrote the first draft of the slides, saved the result and went to bed -the day before I would give the talk. The next day I took a plane to -the location where the meeting should take place, and on the plane I -started up koffice again to polish the talk a bit, only to discover -that kpresenter refused to load its own data file. I cursed a bit and -started making the slides again from memory, to have something to -present when I arrived. I tested that the saved files could be -loaded, and the day seemed to be rescued. I continued to polish the -slides until I suddenly discovered that the saved file could no longer -be loaded into kpresenter. In the end I had to rewrite the slides -three times, condensing the content until the talk became shorter and -shorter. After the talk I was able to pinpoint the problem – -kpresenter wrote inline images in a way itself could not understand. -Eventually that bug was fixed and kpresenter ended up being a great -program to make slides. The point I'm trying to make is that we -expect a program to be able to load its own data files, and it is -embarrassing to its developers if it can't.

- -

Did you ever experience a program failing to load its own data -files from the desktop file browser? It is not a uncommon problem. A -while back I discovered that the screencast recorder -gtk-recordmydesktop would save an Ogg Theora video file the KDE file -browser would refuse to open. No video player claimed to understand -such file. I tracked down the cause being file --mime-type -returning the application/ogg MIME type, which no video player I had -installed listed as a MIME type they would understand. I asked for -file to change its -behavour and use the MIME type video/ogg instead. I also asked -several video players to add video/ogg to their desktop files, to give -the file browser an idea what to do about Ogg Theora files. After a -while, the desktop file browsers in Debian started to handle the -output from gtk-recordmydesktop properly.

- -

But history repeats itself. A few days ago I tested the music -system Rosegarden again, and I discovered that the KDE and xfce file -browsers did not know what to do with the Rosegarden project files -(*.rg). I've reported the -rosegarden problem to BTS and a fix is commited to git and will be -included in the next upload. To increase the chance of me remembering -how to fix the problem next time some program fail to load its files -from the file browser, here are some notes on how to fix it.

- -

The file browsers in Debian in general operates on MIME types. -There are two sources for the MIME type of a given file. The output from -file --mime-type mentioned above, and the content of the -shared MIME type registry (under /usr/share/mime/). The file MIME -type is mapped to programs supporting the MIME type, and this -information is collected from -the -desktop files available in /usr/share/applications/. If there is -one desktop file claiming support for the MIME type of the file, it is -activated when asking to open a given file. If there are more, one -can normally select which one to use by right-clicking on the file and -selecting the wanted one using 'Open with' or similar. In general -this work well. But it depend on each program picking a good MIME -type (preferably -a -MIME type registered with IANA), file and/or the shared MIME -registry recognizing the file and the desktop file to list the MIME -type in its list of supported MIME types.

- -

The /usr/share/mime/packages/rosegarden.xml entry for -the -Shared MIME database look like this:

- -

-<?xml version="1.0" encoding="UTF-8"?>
-<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
-  <mime-type type="audio/x-rosegarden">
-    <sub-class-of type="application/x-gzip"/>
-    <comment>Rosegarden project file</comment>
-    <glob pattern="*.rg"/>
-  </mime-type>
-</mime-info>
-

- -

This states that audio/x-rosegarden is a kind of application/x-gzip -(it is a gzipped XML file). Note, it is much better to use an -official MIME type registered with IANA than it is to make up ones own -unofficial ones like the x-rosegarden type used by rosegarden.

- -

The desktop file of the rosegarden program failed to list -audio/x-rosegarden in its list of supported MIME types, causing the -file browsers to have no idea what to do with *.rg files:

- -

-% grep Mime /usr/share/applications/rosegarden.desktop
-MimeType=audio/x-rosegarden-composition;audio/x-rosegarden-device;audio/x-rosegarden-project;audio/x-rosegarden-template;audio/midi;
-X-KDE-NativeMimeType=audio/x-rosegarden-composition
-%
-

- -

The fix was to add "audio/x-rosegarden;" at the end of the -MimeType= line.

- -

If you run into a file which fail to open the correct program when -selected from the file browser, please check out the output from -file --mime-type for the file, ensure the file ending and -MIME type is registered somewhere under /usr/share/mime/ and check -that some desktop file under /usr/share/applications/ is claiming -support for this MIME type. If not, please report a bug to have it -fixed. :)

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

+ +

start with a Debian machine running Stretch or newer,
build and install the gr-gsm package available from +http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/,
clone the git repostory from https://github.com/Oros42/IMSI-catcher,
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).
go into the IMSI-catcher directory and run 'sudo python simple_IMSI-catcher.py' to extract the IMSI numbers.

+ +

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?

Isenkram with PackageKit support - new version 0.23 available in Debian unstable

25th May 2016

The isenkram -system is a user-focused solution in Debian for handling hardware -related packages. The idea is to have a database of mappings between -hardware and packages, and pop up a dialog suggesting for the user to -install the packages to use a given hardware dongle. Some use cases -are when you insert a Yubikey, it proposes to install the software -needed to control it; when you insert a braille reader list it -proposes to install the packages needed to send text to the reader; -and when you insert a ColorHug screen calibrator it suggests to -install the driver for it. The system work well, and even have a few -command line tools to install firmware packages and packages for the -hardware already in the machine (as opposed to hotpluggable hardware).

- -

The system was initially written using aptdaemon, because I found -good documentation and example code on how to use it. But aptdaemon -is going away and is generally being replaced by -PackageKit, -so Isenkram needed a rewrite. And today, thanks to the great patch -from my college Sunil Mohan Adapa in the FreedomBox project, the -rewrite finally took place. I've just uploaded a new version of -Isenkram into Debian Unstable with the patch included, and the default -for the background daemon is now to use PackageKit. To check it out, -install the isenkram package and insert some hardware dongle -and see if it is recognised.

- -

If you want to know what kind of packages isenkram would propose for -the machine it is running on, you can check out the isenkram-lookup -program. This is what it look like on a Thinkpad X230:

Â«Rapporten ser ikke pÃ¥ informasjonssikkerhet knyttet til personlig integritetÂ»

27th June 2017

Jeg kom over teksten +Â«Killing +car privacy by federal mandateÂ» av Leonid Reyzin pÃ¥ Freedom to +Tinker i dag, og det gleder meg Ã¥ se en god gjennomgang om hvorfor det +er et urimelig inngrep i privatsfÃ¦ren Ã¥ la alle biler kringkaste sin +posisjon og bevegelse via radio. Det omtalte forslaget basert pÃ¥ +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 Ã¥ kunne tenke seg Ã¥ +pÃ¥legge alle biler Ã¥ fjerne nok en bit av innbyggernes privatsfÃ¦re. +Anbefaler alle Ã¥ lese det som stÃ¥r der. + +

Mens jeg tittet litt pÃ¥ DSRC pÃ¥ biler i Norge kom jeg over et sitat +jeg synes er illustrativt for hvordan det offentlige Norge hÃ¥ndterer +problemstillinger rundt innbyggernes privatsfÃ¦re i SINTEF-rapporten +Â«Informasjonssikkerhet +i AutoPASS-brikkerÂ» av Trond Foss:

Tror jeg fortsatt takker nei +til bÃ¥de AutoPASS og holder meg sÃ¥ langt unna det norske helsevesenet +som jeg kan, inntil de har demonstrert og dokumentert at de verdsetter +individets privatsfÃ¦re og personlige integritet hÃ¸yere enn kortsiktig +gevist og samfunnsnytte.

Discharge rate estimate in new battery statistics collector for Debian

23rd May 2016

Yesterday I updated the -battery-stats -package in Debian with a few patches sent to me by skilled and -enterprising users. There were some nice user and visible changes. -First of all, both desktop menu entries now work. A design flaw in -one of the script made the history graph fail to show up (its PNG was -dumped in ~/.xsession-errors) if no controlling TTY was available. -The script worked when called from the command line, but not when -called from the desktop menu. I changed this to look for a DISPLAY -variable or a TTY before deciding where to draw the graph, and now the -graph window pop up as expected.

- -

The next new feature is a discharge rate estimator in one of the -graphs (the one showing the last few hours). New is also the user of -colours showing charging in blue and discharge in red. The percentages -of this graph is relative to last full charge, not battery design -capacity.

- -

The other graph show the entire history of the collected battery -statistics, comparing it to the design capacity of the battery to -visualise how the battery life time get shorter over time. The red -line in this graph is what the previous graph considers 100 percent: - -

- -

In this graph you can see that I only charge the battery to 80 -percent of last full capacity, and how the capacity of the battery is -shrinking. :(

- -

The last new feature is in the collector, which now will handle -more hardware models. On some hardware, Linux power supply -information is stored in /sys/class/power_supply/ACAD/, while the -collector previously only looked in /sys/class/power_supply/AC/. Now -both are checked to figure if there is power connected to the -machine.

I want the courts to be involved before the police can hijack a news site DNS domain (#domstolkontroll)

19th May 2016

I just donated to the -NUUG defence -"fond" to fund the effort in Norway to get the seizure of the news -site popcorn-time.no tested in court. I hope everyone that agree with -me will do the same.

What if the free software system -combined search engine lookups, bittorrent downloads and video playout -and was called Popcorn Time? Would that affect your view? It still -make me worried.

- -

In March 2016, the Norwegian police seized (as in forced NORID to -change the IP address pointed to by it to one controlled by the -police) the DNS domain popcorn-time.no, without any supervision from -the courts. I did not know about the web site back then, and assumed -the courts had been involved, and was very surprised when I discovered -that the police had hijacked the DNS domain without asking a judge for -permission first. I was even more surprised when I had a look at -the web -site content on the Internet Archive, and only found news coverage -about Popcorn Time, not any material published without the right -holders permissions.

- -

The seizure was widely covered in the Norwegian press (see for -example Hegnar Online and -ITavisen -and -NRK), -at first due to the press release sent out by Ãkokrim, but then based -on -protests -from the law professor Olav Torvund and -lawyer -Jon Wessel-Aas.

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:

+ +

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

+ +

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?

What is the best multimedia player in Debian?

8th May 2016

Where I set out to figure out which multimedia player in -Debian claim support for most file formats.

- -

A few years ago, I had a look at the media support for Browser -plugins in Debian, to get an idea which plugins to include in Debian -Edu. I created a script to extract the set of supported MIME types -for each plugin, and used this to find out which multimedia browser -plugin supported most file formats / media types. -The -result can still be seen on the Debian wiki, even though it have -not been updated for a while. But browser plugins are less relevant -these days, so I thought it was time to look at standalone -players.

- -

A few days ago I was tired of VLC not being listed as a viable -player when I wanted to play videos from the Norwegian National -Broadcasting Company, and decided to investigate why. The cause is a -missing MIME type in the VLC -desktop file. In the process I wrote a script to compare the set -of MIME types announced in the desktop file and the browser plugin, -only to discover that there is quite a large difference between the -two for VLC. This discovery made me dig up the script I used to -compare browser plugins, and adjust it to compare desktop files -instead, to try to figure out which multimedia player in Debian -support most file formats.

- -

The result can be seen on the Debian Wiki, as -a -table listing all MIME types supported by one of the packages included -in the table, with the package supporting most MIME types being -listed first in the table.

- -

The best multimedia player in Debian? It is totem, followed by -parole, kplayer, mpv, vlc, smplayer mplayer-gui gnome-mpv and -kmplayer. Time for the other players to update their announced MIME -support?

Epost inn som arkivformat i Riksarkivarens forskrift?

27th April 2017

I disse dager, med frist 1. mai, har Riksarkivaren ute en hÃ¸ring pÃ¥ +sin forskrift. Som en kan se er det ikke mye tid igjen fÃ¸r fristen +som gÃ¥r ut pÃ¥ sÃ¸ndag. Denne forskriften er det som lister opp hvilke +formater det er greit Ã¥ arkivere i +Noark +5-lÃ¸sninger i Norge.

+ +

Jeg fant hÃ¸ringsdokumentene hos +Norsk +ArkivrÃ¥d etter Ã¥ ha blitt tipset pÃ¥ epostlisten til +fri +programvareprosjektet Nikita Noark5-Core, som lager et Noark 5 +Tjenestegresesnitt. Jeg er involvert i Nikita-prosjektet og takket +vÃ¦re min interesse for tjenestegrensesnittsprosjektet har jeg lest en +god del Noark 5-relaterte dokumenter, og til min overraskelse oppdaget +at standard epost ikke er pÃ¥ listen over godkjente formater som kan +arkiveres. HÃ¸ringen med frist sÃ¸ndag er en glimrende mulighet til Ã¥ +forsÃ¸ke Ã¥ gjÃ¸re noe med det. Jeg holder pÃ¥ med +egen +hÃ¸ringsuttalelse, og lurer pÃ¥ om andre er interessert i Ã¥ stÃ¸tte +forslaget om Ã¥ tillate arkivering av epost som epost i arkivet.

+ +

Er du igang med Ã¥ skrive egen hÃ¸ringsuttalelse allerede? I sÃ¥ fall +kan du jo vurdere Ã¥ ta med en formulering om epost-lagring. Jeg tror +ikke det trengs sÃ¥ mye. Her et kort forslag til tekst:

+ +

+ +
Viser til hÃ¸ring sendt ut 2017-02-17 (Riksarkivarens referanse + 2016/9840 HELHJO), og tillater oss Ã¥ sende inn noen innspill om + revisjon av Forskrift om utfyllende tekniske og arkivfaglige + bestemmelser om behandling av offentlige arkiver (Riksarkivarens + forskrift).
+ +
SvÃ¦rt mye av vÃ¥r kommuikasjon foregÃ¥r i dag pÃ¥ e-post.Â Vi + foreslÃ¥r derfor at Internett-e-post, slik det er beskrevet i IETF + RFC 5322, + https://tools.ietf.org/html/rfc5322. bÃ¸r + inn som godkjent dokumentformat.Â Vi foreslÃ¥r at forskriftens + oversikt over godkjente dokumentformater ved innlevering i Â§ 5-16 + endres til Ã¥ 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 pÃ¥ Ã¥ skrive et +forslag om hvordan dette kan gjÃ¸res som vil bli sendt over til +arkivverket sÃ¥ snart det er ferdig. De som er interesserte kan +fÃ¸lge +fremdriften pÃ¥ web.

+ +

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

The Pyra - handheld computer with Debian preinstalled

4th May 2016

A friend of mine made me aware of -The Pyra, a -handheld computer which will be delivered with Debian preinstalled. I -would love to get one of those for my birthday. :)

- -

The machine is a complete ARM-based PC with micro HDMI, SATA, USB -plugs and many others connectors, and include a full keyboard and a 5" -LCD touch screen. The 6000mAh battery is claimed to provide a whole -day of battery life time, but I have not seen any independent tests -confirming this. The vendor is still collecting preorders, and the -last I heard last night was that 22 more orders were needed before -production started.

- -

As far as I know, this is the first handheld preinstalled with -Debian. Please let me know if you know of any others. Is it the -first computer being sold with Debian preinstalled?

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 Ã¥ blokkerer enkelte typer webklienter fra Ã¥ fÃ¥ tilgang. Vet +ikke hvor mange det gjelder, men det gjelder i hvert fall libwww-perl +og curl. For Ã¥ teste selv, kjÃ¸r fÃ¸lgende:

+ +

+% 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 Â«404 Not FoundÂ» for curl i +standardoppsettet, mens den gir Â«200 OKÂ» hvis curl hevder Ã¥ vÃ¦re Opera +versjon 12.0. Offentlig elektronisk postjournal startet blokkeringen +2017-03-02.

+ +

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

+ +

Finnes det juridisk grunnlag for det offentlige Ã¥ diskriminere +webklienter slik det gjÃ¸res 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 +aktÃ¸rene man kan be om innsyn i for Ã¥ forstÃ¥ hva som har skjedd. Men +postjournalen +til DIFI viser kun to dokumenter det siste Ã¥ret mellom DIFI og +Basefarm. +Mimes brÃ¸nn neste, +tenker jeg.

NUUG contests Norwegian police DNS seizure of popcorn-time.no

18th April 2016

It is days like today I am really happy to be a member of -the Norwegian Unix User group, a -member association for those of us believing in free software, open -standards and unix-like operating systems. NUUG announced today it -will -try -to bring the seizure of the DNS domain popcorn-time.no as -unlawful, to stand up for the principle that writing about a -controversial topic is not infringing copyrights, and censuring web -pages by hijacking DNS domain should be decided by the courts, not the -police. The DNS domain was seized by the Norwegian National Authority -for Investigation and Prosecution of Economic and Environmental Crime -a month ago. I hope this bring more paying members to NUUG to give -the association the financial muscle needed to bring this case as far -as it must go to stop this kind of DNS hijacking.

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.
