                <description>&lt;p&gt;Some years ago, in 2016, I
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Experience_and_updated_recipe_for_using_the_Signal_app_without_a_mobile_phone.html&quot;&gt;wrote
for the first time about&lt;/a&gt; the Ring peer to peer messaging system.
It would provide messaging without any central server coordinating the
system and without requiring all users to register a phone number or
own a mobile phone.  Back then, I could not get it to work, and put it
aside until it had seen more development.  A few days ago I decided to
give it another try, and am happy to report that this time I am able
to not only send and receive messages, but also place audio and video
calls.  But only if UDP is not blocked into your network.&lt;/p&gt;

&lt;p&gt;The Ring system changed name earlier this year to
&lt;a href=&quot;https://en.wikipedia.org/wiki/Jami_(software)&quot;&gt;Jami&lt;/a&gt;.  I
tried doing web search for &#39;ring&#39; when I discovered it for the first
time, and can only applaud this change as it is impossible to find
something called Ring among the noise of other uses of that word.  Now
you can search for &#39;jami&#39; and this client and
&lt;a href=&quot;https://jami.net/&quot;&gt;the Jami system&lt;/a&gt; is the first hit at
least on duckduckgo.&lt;/p&gt;

&lt;p&gt;Jami will by default encrypt messages as well as audio and video
calls, and try to send them directly between the communicating parties
if possible.  If this proves impossible (for example if both ends are
behind NAT), it will use a central SIP TURN server maintained by the
Jami project.  Jami can also be a normal SIP client.  If the SIP
server is unencrypted, the audio and video calls will also be
unencrypted.  This is as far as I know the only case where Jami will
do anything without encryption.&lt;/p&gt;

&lt;p&gt;Jami is available for several platforms: Linux, Windows, MacOSX,
Android, iOS, and Android TV.  It is included in Debian already.  Jami
also work for those using F-Droid without any Google connections,
while Signal do not.
&lt;a href=&quot;https://git.jami.net/savoirfairelinux/ring-project/wikis/technical/Protocol&quot;&gt;The
protocol&lt;/a&gt; is described in the Ring project wiki.  The system uses a
distributed hash table (DHT) system (similar to BitTorrent) running
over UDP.  On one of the networks I use, I discovered Jami failed to
work.  I tracked this down to the fact that incoming UDP packages
going to ports 1-49999 were blocked, and the DHT would pick a random
port and end up in the low range most of the time.  After talking to
the developers, I solved this by enabling the dhtproxy in the
settings, thus using TCP to talk to a central DHT proxy instead of

peering directly with others.  I&#39;ve been told the developers are
working on allowing DHT to use TCP to avoid this problem.  I also ran
into a problem when trying to talk to the version of Ring included in
Debian Stable (Stretch).  Apparently the protocol changed between
beta2 and the current version, making these clients incompatible.
Hopefully the protocol will not be made incompatible in the
future.&lt;/p&gt;

&lt;p&gt;It is worth noting that while looking at Jami and its features, I
came across another communication platform I have not tested yet.  The
&lt;a href=&quot;https://en.wikipedia.org/wiki/Tox_(protocol)&quot;&gt;Tox protocol&lt;/a&gt;
and &lt;a href=&quot;https://tox.chat/&quot;&gt;family of Tox clients&lt;/a&gt;.  It might
become the topic of a future blog post.&lt;/p&gt;

                <description>&lt;p&gt;The first book I published,
&lt;a href=&quot;http://www.free-culture.cc/&quot;&gt;Free Culture by Lawrence
Lessig&lt;/a&gt;, is still selling a few copies.  Not a lot, but enough to
have contributed slightly over $500 to the &lt;a
href=&quot;https://creativecommons.org/&quot;&gt;Creative Commons Corporation&lt;/a&gt;
so far.  All the profit is sent there. Most books are still sold via
Amazon (83 copies), with Ingram second (49) and Lulu (12) and Machette (7) as
minor channels.  Bying directly from Lulu bring the largest cut to
Creative Commons.  The English Edition sold 80 copies so far, the
French 59 copies, and Norwegian only 8 copies.  Nothing impressive,
but nice to see the work we put down is still being appreciated.  The
ebook edition is available for free from
&lt;a href=&quot;https://github.com/petterreinholdtsen/free-culture-lessig&quot;&gt;Github&lt;/a&gt;.&lt;/p&gt;

  &lt;td align=&quot;right&quot;&gt;10&lt;/td&gt;
&lt;/tr&gt;

&lt;/table&gt;

&lt;p&gt;It is fun to see the French edition being more popular than the
English one.&lt;/p&gt;

&lt;p&gt;If you would like to translate and publish the book in your native
language, I would be happy to help make it happen.  Please get in

                <description>&lt;p&gt;Just 15 days ago,
&lt;ahref=&quot;http://people.skolelinux.org/pere/blog/MIME_type__text_vnd_sosi__for_SOSI_map_data.html&quot;&gt;I
mentioned&lt;/a&gt; my submission to IANA to register an official MIME type
for the SOSI vector map format.  This morning, just an hour ago, I was
notified that
&lt;a href=&quot;https://www.iana.org/assignments/media-types/text/vnd.sosi&quot;&gt;the
MIME type &quot;text/vnd.sosi&quot;&lt;/a&gt; is registered for this format.  In
addition to this registration, my
&lt;a href=&quot;https://github.com/file/file/blob/master/magic/Magdir/sosi&quot;&gt;file(1)
patch for a pattern matching rule for SOSI files&lt;/a&gt; has been accepted
into the official source of that program (pending a new release), and
I&#39;ve been told by the team behind
&lt;a href=&quot;https://www.nationalarchives.gov.uk/PRONOM/&quot;&gt;PRONOM&lt;/a&gt; that
the SOSI format will be included in the next release of PRONOM, which
they plan to release this summer around July.&lt;/p&gt;

&lt;p&gt;I am very happy to see all of this fall into place, for use by
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/&quot;&gt;the
Noark 5 Tjenestegrensesnitt&lt;/a&gt; implementations.&lt;/p&gt;

                <pubDate>Sun, 2 Jun 2019 23:55:00 +0200</pubDate>
                <description>&lt;p&gt;A while back a college and friend from Debian and the Skolelinux /
Debian Edu project approached me, asking if I knew someone that might
be interested in helping out with a technology project he was running
as a teacher at &lt;a href=&quot;https://www.ecolefrancodanoise.dk/&quot;&gt;L&#39;école
franco-danoise&lt;/a&gt; - the Danish-French school and kindergarden.  The
kids were building robots, rovers.  The story behind it is to build a
rover for use
&lt;a href=&quot;http://blog.ecolefrancodanoise.dk/first-week-on-the-dark-side&quot;&gt;on
the dark side of the moon&lt;/a&gt;, and remote control it.  As travel cost
was a bit high for the final destination, and they wanted to test the
concept first, he was looking for volunteers to host a rover for the
kids to control in a foreign country.  I ended up volunteering as a
host, and last week the rover arrived.  It took a while to arrive
after &lt;a href=&quot;http://blog.ecolefrancodanoise.dk/model-moms&quot;&gt;it was
built and shipped&lt;/a&gt;, because of customs confusion.  Luckily we were
able fix it quickly with help from my colleges at work.&lt;/p&gt;

&lt;p&gt;This is what it looked like when the rover arrived.  Note the cute
eyes looking up on me from the wrapping&lt;/p&gt;

&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2019-06-02-robot-dark-side-of-moon-esken-med-det-rare-i.jpeg&quot; width=&quot;32%&quot; style=&quot;clear:left&quot;/&gt;
&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2019-06-02-robot-dark-side-of-moon-den-ser-meg.jpeg&quot; width=&quot;32%&quot; style=&quot;clear:left&quot;/&gt;
&lt;img src=&quot;http://people.skolelinux.org/pere/blog/images/2019-06-02-robot-dark-side-of-moon-en-skrue-loes.jpeg&quot; width=&quot;32%&quot; style=&quot;clear:left&quot;/&gt;

&lt;p style=&quot;text-align:left&quot;&gt;Once the robot arrived, we needed to track
down batteries and figure out how to build custom firmware for it with
the appropriate wifi settings.  I asked a friend if I could get two
18650 batteries from his pile of Tesla batteries (he had them from the
wrack of a crashed Tesla), so now the rover is running on Tesla
batteries.&lt;/p&gt;

&lt;p&gt;Building
&lt;a href=&quot;https://gitlab.com/ecolefrancodanoise/arduino-efd/&quot;&gt;the rover
firmware&lt;/a&gt; proved a bit harder, as the code did not work out of the
box with the Arduino IDE package in Debian Buster.  I suspect this is
due to a unsolved
&lt;a href=&quot;https://github.com/arduino/Arduino/pull/2703&quot;&gt; license problem
with arduino&lt;/a&gt; blocking Debian from upgrading to the latest version.
In the end we gave up debugging why the IDE failed to find the
required libraries, and ended up using the Arduino Makefile from the
&lt;a href=&quot;https://tracker.debian.org/pkg/arduino-mk&quot;&gt;arduino-mk Debian
package&lt;/a&gt; instead.  Unfortunately the camera library is missing from
the Arduino environment in Debian, so we disabled the camera support
for the first firmware build, to get something up and running.  With
this reduced firmware, the robot could be controlled via the
controller server, driving around and measuring distance using its
internal acoustic sensor.&lt;/p&gt;

&lt;p&gt;Next, With some help from my friend in Denmark, which checked in the
camera library into the gitlab repository for me to use, we were able
to build a new and more complete version of the firmware, and the
robot is now up and running.  This is what the &quot;commander&quot; web page
look like after taking a measurement and a snapshot:&lt;/p&gt;

                <pubDate>Wed, 22 May 2019 11:30:00 +0200</pubDate>
                <description>&lt;p&gt;This morning,  a new release of 
&lt;a href=&quot;https://gitlab.com/OsloMet-ABI/nikita-noark5-core/&quot;&gt;Nikita
Noark 5 core project&lt;/a&gt; was
&lt;a href=&quot;https://lists.nuug.no/pipermail/nikita-noark/2019-May/000468.html&quot;&gt;announced
on the project mailing list&lt;/a&gt;.  The Nikita 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 0.4
since version 0.3, see the email link above for links to a demo site:&lt;/p&gt;

&lt;ul&gt;

  &lt;li&gt;Roll out OData handling to all endpoints where applicable&lt;/li&gt;
  &lt;li&gt;Changed the relation key for &quot;ny-journalpost&quot; to the official one.&lt;/li&gt;
  &lt;li&gt;Better link generation on outgoing links.&lt;/li&gt;
  &lt;li&gt;Tidy up code and make code and approaches more consistent throughout
   the codebase&lt;/li&gt;
  &lt;li&gt;Update rels to be in compliance with updated version in the
   interface standard&lt;/li&gt;
  &lt;li&gt;Avoid printing links on empty objects as they can&#39;t have links&lt;/li&gt;
  &lt;li&gt;Small bug fixes and improvements&lt;/li&gt;
  &lt;li&gt;Start moving generation of outgoing links to @Service layer so access
   control can be used when generating links&lt;/li&gt;
  &lt;li&gt;Log exception that was being swallowed so it&#39;s traceable&lt;/li&gt;
  &lt;li&gt;Fix name mapping problem&lt;/li&gt;
  &lt;li&gt;Update templated printing so templated should only be printed if it
   is set true. Requires more work to roll out across entire
   application.&lt;/li&gt;
  &lt;li&gt;Remove Record-&gt;DocumentObject as per domain model of n5v4&lt;/li&gt;
  &lt;li&gt;Add ability to delete lists filtered with OData&lt;/li&gt;
  &lt;li&gt;Return NO_CONTENT (204) on delete as per interface standard&lt;/li&gt;
  &lt;li&gt;Introduce support for ConstraintViolationException exception&lt;/li&gt;
  &lt;li&gt;Make Service classes extend NoarkService&lt;/li&gt;
  &lt;li&gt;Make code base respect X-Forwarded-Host, X-Forwarded-Proto and
   X-Forwarded-Port&lt;/li&gt;
  &lt;li&gt;Update CorrespondencePart* code to be more in line with Single
   Responsibility Principle&lt;/li&gt;
  &lt;li&gt;Make package name follow directory structure&lt;/li&gt;
  &lt;li&gt;Make sure Document number starts at 1, not 0&lt;/li&gt;
  &lt;li&gt;Fix isues discovered by FindBugs&lt;/li&gt;
  &lt;li&gt;Update from Date to ZonedDateTime&lt;/li&gt;
  &lt;li&gt;Fix wrong tablename&lt;/li&gt;
  &lt;li&gt;Introduce Service layer tests&lt;/li&gt;
  &lt;li&gt;Improvements to CorrespondencePart&lt;/li&gt;
  &lt;li&gt;Continued work on Class / Classificationsystem&lt;/li&gt;
  &lt;li&gt;Fix feature where authors were stored as storageLocations&lt;/li&gt;
  &lt;li&gt;Update HQL builder for OData&lt;/li&gt;
  &lt;li&gt;Update OData search capability from webpage&lt;/li&gt;
  
&lt;/ul&gt;

                <description>&lt;p&gt;As part of my involvement in the work to
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard&quot;&gt;standardise
a REST based API for Noark 5&lt;/a&gt;, the Norwegian archiving standard, I

and &lt;a href=&quot;https://www.nationalarchives.gov.uk/PRONOM/&quot;&gt;PRONOM
code&lt;/a&gt; for the SOSI file format.  The background is that there is a
set of formats approved for long term storage and archiving in Norway,
and among these formats, SOSI is the only format missing a MIME type
and PRONOM code.&lt;/p&gt;

&lt;p&gt;What is SOSI, you might ask?  To quote Wikipedia: SOSI is short for
Samordnet Opplegg for Stedfestet Informasjon (literally &quot;Coordinated
Approach for Spatial Information&quot;, but more commonly expanded in
English to Systematic Organization of Spatial Information).  It is a
text based file format for geo-spatial vector information used in
Norway.  Information about the SOSI format can be found in English
from &lt;a href=&quot;https://en.wikipedia.org/wiki/SOSI&quot;&gt;Wikipedia&lt;/a&gt;.  The
specification is available in Norwegian from
&lt;a href=&quot;https://www.kartverket.no/geodataarbeid/Standarder/SOSI/&quot;&gt;the
Norwegian mapping authority&lt;/a&gt;.  The SOSI standard, which originated
in the beginning of nineteen eighties, was the inspiration and formed the
basis for the XML based
&lt;a href=&quot;https://en.wikipedia.org/wiki/Geography_Markup_Language&quot;&gt;Geography
Markup Language&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;I have so far written
&lt;a href=&quot;https://github.com/file/file/pull/67&quot;&gt;a pattern matching
rule&lt;/a&gt; for the file(1) unix tool to recognize SOSI files, submitted
a request to the PRONOM project to have a PRONOM ID assigned to the
format (reference TNA1555078202S60), and today send a request to IANA
to register the &quot;text/vnd.sosi&quot; MIME type for this format (referanse
&lt;a href=&quot;https://tools.iana.org/public-view/viewticket/1143144&quot;&gt;IANA
#1143144&lt;/a&gt;).  If all goes well, in a few months, anyone implementing
the Noark 5 Tjenestegrensesnitt API spesification should be able to
use an official MIME type and PRONOM code for SOSI files.  In
addition, anyone using SOSI files on Linux should be able to
automatically recognise the format and web sites handing out SOSI
files can begin providing a more specific MIME type.  So far, SOSI
files has been handed out from web sites using the
&quot;application/octet-stream&quot; MIME type, which is just a nice way of
stating &quot;I do not know&quot;.  Soon, we will know. :)&lt;/p&gt;

                <title>PlantUML for text based UML diagram modelling - nice free software</title>
                <link>http://people.skolelinux.org/pere/blog/PlantUML_for_text_based_UML_diagram_modelling___nice_free_software.html</link>
                <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/PlantUML_for_text_based_UML_diagram_modelling___nice_free_software.html</guid>
                <pubDate>Mon, 25 Mar 2019 09:35:00 +0100</pubDate>
                <description>&lt;p&gt;As part of my involvement with the
&lt;a href=&quot;https://gitlab.com/OsloMet-ABI/nikita-noark5-core/&quot;&gt;Nikita
Noark 5 core project&lt;/a&gt;, I have been proposing improvements to the
API specification created by &lt;a href=&quot;https://www.arkivverket.no/&quot;&gt;The
National Archives of Norway&lt;/a&gt; and helped migrating the text from a
version control system unfriendly binary format (docx) to Markdown in
git.  Combined with the migration to a public git repository (on
github), this has made it possible for anyone to suggest improvement
to the text.&lt;/p&gt;

&lt;p&gt;The specification is filled with UML diagrams.  I believe the
original diagrams were modelled using Sparx Systems Enterprise
Architect, and exported as EMF files for import into docx.  This
approach make it very hard to track changes using a version control
system.  To improve the situation I have been looking for a good text
based UML format with associated command line free software tools on
Linux and Windows, to allow anyone to send in corrections to the UML
diagrams in the specification.  The tool must be text based to work
with git, and command line to be able to run it automatically to
generate the diagram images.  Finally, it must be free software to
allow anyone, even those that can not accept a non-free software
license, to contribute.&lt;/p&gt;

&lt;p&gt;I did not know much about free software UML modelling tools when I
started.  I have used dia and inkscape for simple modelling in the
past, but neither are available on Windows, as far as I could tell.  I
came across a nice
&lt;a href=&quot;https://modeling-languages.com/text-uml-tools-complete-list/&quot;&gt;list
of text mode uml tools&lt;/a&gt;, and tested out a few of the tools listed
there.  &lt;a href=&quot;http://plantuml.com/&quot;&gt;The PlantUML tool&lt;/a&gt; seemed
most promising.  After verifying that the packages
&lt;a href=&quot;https://tracker.debian.org/pkg/plantuml&quot;&gt;is available in
Debian&lt;/a&gt; and found &lt;a href=&quot;https://github.com/plantuml/plantuml&quot;&gt;its
Java source&lt;/a&gt; under a GPL license on github, I set out to test if it
could represent the diagrams we needed, ie the ones currently in
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/&quot;&gt;the
Noark 5 Tjenestegrensesnitt specification&lt;/a&gt;.  I am happy to report
that it could represent them, even thought it have a few warts here
and there.&lt;/p&gt;

&lt;p&gt;After a few days of modelling I completed the task this weekend.  A
temporary link to the complete set of diagrams (original and from
PlantUML) is available in
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/issues/76&quot;&gt;the
github issue discussing the need for a text based UML format&lt;/a&gt;, but
please note I lack a sensible tool to convert EMF files to PNGs, so
the &quot;original&quot; rendering is not as good as the original was in the
publised PDF.&lt;/p&gt;

&lt;p&gt;Here is an example UML diagram, showing the core classes for
keeping metadata about archived documents:&lt;/p&gt;

&lt;/pre&gt;

&lt;p&gt;&lt;a href=&quot;http://plantuml.com/class-diagram&quot;&gt;The format&lt;/a&gt; is quite
compact, with little redundant information.  The text expresses
entities and relations, and there is little layout related fluff.  One
can reuse content by using include files, allowing for consistent
naming across several diagrams.  The include files can be standalone
PlantUML too.  Here is the content of
&lt;tt&gt;media/uml-class-arkivskaper.iuml&lt;tt&gt;:&lt;/p&gt;

&lt;pre&gt;
@startuml
class Arkivstruktur.Arkivskaper &lt;Arkivenhet&gt; {
  +arkivskaperID : string
  +arkivskaperNavn : string
  +beskrivelse : string [0..1]
}
@enduml
&lt;/pre&gt;

&lt;p&gt;This is what the complete diagram for the PlantUML notation above
look like:&lt;/p&gt;

&lt;p&gt;&lt;img width=&quot;80%&quot; src=&quot;http://people.skolelinux.org/pere/blog/images/2019-03-25-noark5-plantuml-diagrameksempel.png&quot;&gt;&lt;/p&gt;

&lt;p&gt;A cool feature of PlantUML is that the generated PNG files include
the entire original source diagram as text.  The source (with include
statements expanded) can be extracted using for example
&lt;tt&gt;exiftool&lt;/tt&gt;.  Another cool feature is that parts of the entities
can be hidden after inclusion.  This allow to use include files with
all attributes listed, even for UML diagrams that should not list any
attributes.&lt;/p&gt;

&lt;p&gt;The diagram also show some of the warts.  Some times the layout
engine place text labels on top of each other, and some times it place
the class boxes too close to each other, not leaving room for the
labels on the relationship arrows.  The former can be worked around by
placing extra newlines in the labes (ie &quot;\n&quot;).  I did not do it here
to be able to demonstrate the issue.  I have not found a good way
around the latter, so I normally try to reduce the problem by changing
from vertical to horizontal links to improve the layout.&lt;/p&gt;

&lt;p&gt;All in all, I am quite happy with PlantUML, and very impressed with
how quickly its lead developer responds to questions.  So far I got an
answer to my questions in a few hours when I send an email.  I
definitely recommend looking at PlantUML if you need to make UML
diagrams.  Note, PlantUML can draw a lot more than class relations.
Check out the documention for a complete list. :)&lt;/p&gt;

                <pubDate>Sun, 24 Mar 2019 14:30:00 +0100</pubDate>
                <description>&lt;p&gt;Yesterday,  a new release of 
&lt;a href=&quot;https://gitlab.com/OsloMet-ABI/nikita-noark5-core/&quot;&gt;Nikita
Noark 5 core project&lt;/a&gt; was
&lt;a href=&quot;https://lists.nuug.no/pipermail/nikita-noark/2019-March/000451.html&quot;&gt;announced
on the project mailing list&lt;/a&gt;.  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 0.3
since version 0.2.1 (from NEWS.md):&lt;/p&gt;

&lt;ul&gt;
  &lt;li&gt;Improved ClassificationSystem and Class behaviour.&lt;/li&gt;
  &lt;li&gt;Tidied up known inconsistencies between domain model and hateaos links.&lt;/li&gt;
  &lt;li&gt;Added experimental code for blockchain integration.  &lt;/li&gt;
  &lt;li&gt;Make token expiry time configurable at upstart from properties file.&lt;/li&gt;
  &lt;li&gt;Continued work on OData search syntax.&lt;/li&gt;
  &lt;li&gt;Started work on pagination for entities, partly implemented for Saksmappe.&lt;/li&gt;
  &lt;li&gt;Finalise ClassifiedCode Metadata entity.&lt;/li&gt;
  &lt;li&gt;Implement mechanism to check if authentication token is still
   valid.  This allow the GUI to return a more sensible message to the
   user if the token is expired.&lt;/li&gt;
  &lt;li&gt;Reintroduce browse.html page to allow user to browse JSON API using
   hateoas links.&lt;/li&gt;
  &lt;li&gt;Fix bug in handling file/mappe sequence number.  Year change was
   not properly handled.&lt;/li&gt;
  &lt;li&gt;Update application yml files to be in sync with current development.&lt;/li&gt;
  &lt;li&gt;Stop &#39;converting&#39; everything to PDF using libreoffice.  Only
   convert the file formats doc, ppt, xls, docx, pptx, xlsx, odt, odp
   and ods.&lt;/li&gt;
  &lt;li&gt;Continued code style fixing, making code more readable.&lt;/li&gt;
  &lt;li&gt;Minor bug fixes.&lt;/li&gt;
  
&lt;/ul&gt;

                <pubDate>Mon, 11 Mar 2019 16:00:00 +0100</pubDate>
                <description>&lt;p&gt;Et virksomhetsarkiv for meg, er et arbeidsverktøy der en enkelt kan
finne informasjonen en trenger når en trenger det, og der
virksomhetens samlede kunnskap er tilgjengelig. Det må være greit å
finne frem i, litt som en bibliotek. Men der et bibliotek gjerne tar
vare på offentliggjort informasjon som er tilgjengelig flere steder,
tar et arkiv vare på virksomhetsintern og til tider personlig
informasjon som ofte kun er tilgjengelig fra et sted.&lt;/p&gt;

&lt;p&gt;Jeg mistenker den eneste måten å sikre at arkivet inneholder den
samlede kunnskapen i en virksomhet, er å bruke det som virksomhetens
kunnskapslager. Det innebærer å automatisk kopiere (brev, epost,
SMS-er etc) inn i arkivet når de sendes og mottas, og der filtrere
vekk det en ikke vil ta vare på, og legge på metadata om det som er
samlet inn for enkel gjenfinning. En slik bruk av arkivet innebærer at
arkivet er en del av daglig virke, ikke at det er siste hvilested for
informasjon ingen lenger har daglig bruk for. For å kunne være en del
av det daglige virket må arkivet enkelt kunne integreres med andre
systemer.  I disse dager betyr det å tilby arkivet som en
nett-tjeneste til hele virksomheten, tilgjengelig for både mennesker
og datamaskiner.  Det betyr i tur å både tilby nettsider og et
maskinlesbart grensesnitt.&lt;/p&gt;

&lt;p&gt;For noen år siden erkjente visjonære arkivarer fordelene med et
standardisert maskinlesbart grensesnitt til organisasjonens arkiv.  De
gikk igang med å lage noe de kalte
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/&quot;&gt;Noark
5 Tjenestegrensesnitt&lt;/a&gt;.  Gjort riktig, så åpner slike maskinlesbare
grensesnitt for samvirke på tvers av uavhengige programvaresystemer.
Gjort feil, vil det blokkere for samvirke og bidra til
leverandørinnlåsing.  For å gjøre det riktig så må grensesnittet være
klart og entydig beskrevet i en spesifikasjon som gjør at
spesifikasjonen tolkes på samme måte uavhengig av hvem som leser den,
og uavhengig av hvem som tar den i bruk.&lt;/p&gt;

&lt;p&gt;For å oppnå klare og entydige beskrivelser i en spesifikasjon, som
trengs for å kunne få en fri og åpen standard (se
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Fri_og__pen_standard__slik_Digistan_ser_det.html&quot;&gt;Digistan-definisjon&lt;/a&gt;),
så trengs det en åpen og gjennomsiktig inngangsport med lav terskel,
der de som forsøker å ta den i bruk enkelt kan få inn korreksjoner,
etterlyse klargjøringer og rapportere uklarheter i spesifikasjonen.
En trenger også automatiserte datasystemer som måler og sjekker at et
gitt grensesnitt fungerer i tråd med spesifikasjonen.&lt;/p&gt;

&lt;p&gt;For Noark 5 Tjenestegrensesnittet er det nå etablert en slik åpen
og gjennomsiktig inngangsport på prosjekttjenesten github.  Denne
inngangsporten består først og fremst av en åpen portal som lar enhver
se hva som er gjort av endringer i spesifikasjonsteksten over tid, men
det hører også med et åpent &amp;quot;diskusjonsforum&amp;quot; der en kan
komme med endringsforslag og forespørsler om klargjøringer.  Alle
registrerte brukere på github kan bidra med innspill til disse
henvendelsene.&lt;/p&gt;

&lt;p&gt;I samarbeide med Arkivverket har jeg fått opprettet et git-depot
med spesifikasjonsteksten for tjenestegrensesnittet, der det er lagt
inn historikk for endringer i teksten de siste årene, samt lagt inn
endringsforslag og forespørsler om klargjøring av teksten.  Bakgrunnen
for at jeg bidro med dette er at jeg er involvert i
&lt;a href=&quot;https://gitlab.com/OsloMet-ABI/nikita-noark5-core&quot;&gt;Nikita-prosjektet&lt;/a&gt;,
som lager en fri programvare-utgave av Noark 5 Tjenestegrensesnitt.
Det er først når en forsøker å lage noe i tråd med en spesifikasjon at
en oppdager hvor mange detaljer som må beskrives i spesifikasjonen for
å sikre samhandling.&lt;/p&gt;

&lt;p&gt;Spesifikasjonen vedlikeholdes i et rent tekstformat, for å ha et
format egnet for versjonskontroll via versjontrollsystemet git.  Dette
gjør det både enkelt å se konkret hvilke endringer som er gjort når,
samt gjør det praktisk mulig for enhver med github-konto å sende inn
endringsforslag med formuleringer til spesifikasjonsteksten.  Dette
tekstformatet vises frem som nettsider på github, slik at en ikke
trenger spesielle verktøy for å se på siste utgave av
spesifikasjonen.&lt;/p&gt;

&lt;p&gt;Fra dette rene tekstformatet kan det så avledes ulike formater, som
HTML for websider, PDF for utskrift på papir og ePub for lesing med
ebokleser.  Avlednings-systemet (byggesystemet) bruker i dag
verktøyene pandoc, latex, docbook-xsl og GNU make til
transformasjonen.  Tekstformatet som brukes dag er
&lt;a href=&quot;https://www.markdownguide.org/&quot;&gt;Markdown&lt;/a&gt;, men det vurderes
å
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/issues/9&quot;&gt;endre
til formatet RST&lt;/a&gt; i fremtiden for bedre styring av utseende på
PDF-utgaven.&lt;/p&gt;

&lt;p&gt;Versjonskontrollsystemet git ble valgt da det er både fleksibelt,
avansert og enkelt å ta i bruk. Github ble valgt (foran f.eks. Gitlab
som vi bruker i Nikita), da Arkivverket allerede hadde tatt i bruk
Github i andre sammenhenger.&lt;/p&gt;

&lt;p&gt;Enkle endringer i teksten kan gjøres av priviligerte brukere
direkte i nettsidene til Github, ved å finne aktuell fil som skal
endres (f.eks. kapitler/03-konformitet.md), klikke på den lille
bokstaven i høyre hjørne over teksten. Det kommer opp en nettside der
en kan endre teksten slik en ønsker. Når en er fornøyd med endringen
så må endringen &amp;quot;sjekkes inn&amp;quot; i historikken. Det gjøres ved
å gi en kort beskrivelse av endringen (beskriv helst hvorfor endringen
trengs, ikke hva som er endret), under overskriften &amp;quot;Commit
changes&amp;quot;. En kan og bør legge inn en lengre forklaring i det
større skrivefeltet, før en velger om endringen skal sendes direkte
til &#39;master&#39;-grenen (dvs. autorativ utgave av spesifikasjonen) eller
om en skal lage en ny gren for denne endringen og opprette en
endringsforespørsel (aka &amp;quot;Pull Request&amp;quot;/PR). Når alt dette
er gjort kan en velge &amp;quot;Commit changes&amp;quot; for å sende inn
endringen. Hvis den er lagt inn i &amp;quot;master&amp;quot;-grenen så er den
en offisiell del av spesifikasjonen med en gang.  Hvis den derimot er
en endringsforespørsel, så legges den inn i
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/pulls&quot;&gt;listen
over forslag til endringer&lt;/a&gt; som venter på korrekturlesing og
godkjenning.&lt;/p&gt;

&lt;p&gt;Større endringer (for eksempel samtidig endringer i flere filer)
gjøres enklest ved å hente ned en kopi av git-depoet lokalt og gjøre
endringene der før endringsforslaget sendes inn. Denne prosessen er
godt beskrivet i dokumentasjon fra github.  Git-prosjektet som skal
&amp;quot;klones&amp;quot; er
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/&quot;&gt;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;For å registrere nye utfordringer (issues) eller kommentere på
eksisterende utfordringer benyttes nettsiden
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/issues&quot;&gt;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/issues&lt;/a&gt;.
I skrivende stund er det 48 åpne og 11 avsluttede utfordringer.  Et
forslag til hva som bør være med når en beskriver en utfordring er
tilgjengelig som utfordring
&lt;a href=&quot;https://github.com/arkivverket/noark5-tjenestegrensesnitt-standard/issues/14&quot;&gt;#14&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;For å bygge en PDF-utgave av spesifikasjonen så bruker jeg i dag en
Debian GNU/Linux-maskin med en rekke programpakker installert.  Når
dette er på plass, så holder det å kjøre kommandoen &#39;make pdf html&#39; på
kommandolinjen, vente ca. 20 sekunder, før spesifikasjon.pdf og
spesifikasjon.html ligger klar på disken. Verktøyene for bygging av
PDF, HTML og ePub-utgave er også tilgjengelig på Windows og
MacOSX.&lt;/p&gt;

&lt;p&gt;Github bidrar med rammeverket.  Men for at åpent vedlikehold av
spesifikasjonen skal fungere, så trengs det folk som bidrar med sin
tid og kunnskap.  Arkivverket har sagt de skal bidra med innspill og
godkjenne forslag til endringer, men det blir størst suksess hvis alle
som bruker og lager systemer basert på Noark 5 Tjenestegrensesnitt
bidrar med sin kunnskap og kommer med forslag til forebedringer.  Jeg
stiller.  Blir du med?&lt;/p&gt;

&lt;p&gt;Det er viktig å legge til rette for åpen diskusjon blant alle
interesserte, som ikke krever at en må godta lange kontrakter med
vilkår for deltagelse. Inntil Arkivverket dukker opp på IRC har vi
laget en IRC-kanal der interesserte enkelt kan orientere seg og
diskutere tjenestegrensesnittet. Alle er velkommen til å ta turen
innom
&lt;a href=&quot;https://webchat.freenode.net/?channels=nikita&quot;&gt;#nikita&lt;/a&gt;
(f.eks. via irc.freenode.net) for å møte likesinnede.&lt;/p&gt;

&lt;p&gt;Det holder dog ikke å ha en god spesifikasjon, hvis ikke de som tar
den i bruk gjør en like god jobb. For å automatisk teste om et konkret
tjenestegrensesnitt følger (min) forståelse av
spesifikasjonsdokumentet, har jeg skrevet et program som kobler seg
opp til et Noark 5v4 REST-tjeneste og tester alt den finner for å se
om det er i henhold til min tolkning av spesifikasjonen.  Dette
verktøyet er tilgjengelig fra
&lt;a href=&quot;https://github.com/petterreinholdtsen/noark5-tester&quot;&gt;https://github.com/petterreinholdtsen/noark5-tester&lt;/a&gt;,
og brukes daglig mens vi utvikler Nikita for å sikre at vi ikke
introduserer nye feil.  Hvis en skal sikre samvirke på tvers av ulike
systemer er det helt essensielt å kunne raskt og automatisk sjekke at
tjenestegrensesnittet oppfører seg som forventet.  Jeg håper andre som
lager sin utgave av tjenestegrensesnittet vi bruke dette verktøyet,
slik at vi tidlig og raskt kan oppdage hvor vi har tolket
spesifikasjonen ulikt, og dermed få et godt grunnlag for å gjøre
spesifikasjonsteksten enda klarere og bedre.&lt;/p&gt;

&lt;p&gt;Dagens beskrivelse av Noark 5 Tjenestegrensesnitt er et svært godt
utgangspunkt for å gjøre virksomhetens arkiv til et dynamisk og
sentralt arbeidsverktøy i organisasjonen.  Blir du med å gjøre den
enda bedre?&lt;/p&gt;

                <description>&lt;p&gt;&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Er_billettautomatene_til_kollektivtrafikken_i_Oslo_uten_sikkerhetsoppdateringer_.html&quot;&gt;For
syv år siden&lt;/a&gt; oppdaget jeg at billettautomater for
kollektivtrafikken i Oslo kjørte
&lt;a href=&quot;http://en.wikipedia.org/wiki/Windows_2000&quot;&gt;Windows 2000
Professional&lt;/a&gt;.  Operativsystemet har ikke fått sikkerhetsfikser fra
Microsoft siden 2010-07-13 i følge dem selv.  Den samme versjonen av
operativsystemet var i bruk
&lt;a href=&quot;http://people.skolelinux.org/pere/blog/Fortsatt_ingen_sikkerhetsoppdateringer_for_billettautomatene_til_kollektivtrafikken_i_Oslo_.html&quot;&gt;for
to og et halvt år siden&lt;/a&gt;, og jammen er det ikke også i bruk den dag
i dag:&lt;/p&gt;

&lt;p align=&quot;center&quot;&gt;&lt;a href=&quot;http://people.skolelinux.org/pere/blog/images/2019-02-13-ruter-win2000pro.jpeg&quot;&gt;&lt;img width=&quot;40%&quot; src=&quot;http://people.skolelinux.org/pere/blog/images/2019-02-13-ruter-win2000pro.jpeg&quot; alt=&quot;[Bilde av Ruters billettautomat med Windows 2000-feilmelding]&quot;&gt;&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Kanskje det hadde vært
&lt;a href=&quot;https://www.aftenposten.no/osloby/i/awqgO/Her-kjorer-du-gratis-trikk-og-buss&quot;&gt;bedre
med gratis kollektivtrafikk&lt;/A&gt;, slik at vi slapp å stole på
datakompetansen til Ruter for å verne våre privatliv samt holde
personopplysninger og betalingsinformasjon unna uvedkommende.  Eneste
måten å sikre at hvor en befinner seg ikke kan hentes ut fra Ruters
systemer er å betale enkeltbilletter med kontanter.  Jeg vet at Ruter
har en god historie om hvor personvernvennlige mobil-app og
RFID-kortene er, men den historien er ikke mulig å uavhengig
kontrollere uten priviligert tilgang til interne system og blir dermed
bare nok en god historie basert på tillit til de som forteller
historien.  Det er ikke slik en sikrer privatsfæren.  Det gjør en ved
å sikre at det ikke (kan) registreres informasjon om ens person.&lt;/p&gt;

&lt;p&gt;Som vanlig, hvis du bruker Bitcoin og ønsker å vise din støtte til
det jeg driver med, setter jeg pris på om du sender Bitcoin-donasjoner
til min adresse
&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.
Merk, betaling med bitcoin er ikke anonymt. :)&lt;/p&gt;
