  32         <p><a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>
  33 keep gaining new users.  Some weeks ago, a person showed up on IRC,
  34 <a href="irc://irc.debian.org/#debian-edu">#debian-edu</a>, with a
  35 wish to contribute, and I managed to get a interview with this great
  36 contributor Roger Marsal to learn more about his background.</p>
  37
  38 <p><strong>Who are you, and how do you spend your days?</strong></p>
  39
  40 <p>My name is Roger Marsal, I'm 27 years old (1986 generation) and I
  41 live in Barcelona, Spain. I've got a strong business background and I
  42 work as a patrimony manager and as a real estate agent.  Additionally,
  43 I've co-founded a British based tech company that is nowadays on the
  44 last development phase of a new social networking concept.</p>
  45
  46 <p>I'm a Linux enthusiast that started its journey with Ubuntu four years
  47 ago and have recently switched to Debian seeking rock solid stability
  48 and as a necessary step to gain expertise.</p>
  49
  50 <p>In a nutshell, I spend my days working and learning as much as I
  51 can to face both my job, entrepreneur project and feed my Linux
  52 hunger.</p>
  53
  54 <p><strong>How did you get in contact with the Skolelinux / Debian Edu
  55 project?</strong></p>
  56
  57 <p>I discovered the <a href="http://www.ltsp.org/">LTSP</a> advantages
  58 with "Ubuntu 12.04 alternate install" and after a year of use I
  59 started looking for an alternative.  Even though I highly value and
  60 respect the Ubuntu project, I thought it was necessary for me to
  61 change to a more robust and stable alternative.  As far as I was using
  62 Debian on my personal laptop I thought it would be fine to install
  63 Debian and configure an LTSP server myself.  Surprised, I discovered
  64 that the Debian project also supported a kind of Edubuntu equivalent,
  65 and after having some pain I obtained a Debian Edu network up and
  66 running.  I just loved it.</p>
  67
  68 <p><strong>What do you see as the advantages of Skolelinux / Debian
  69 Edu?</strong></p>
  70
  71 <p>I found a main advantage in that, once you know "the tips and
  72 tricks", a new installation just works out of the box. It's the most
  73 complete alternative I've found to create an LTSP network. All the
  74 other distributions seems to be made of plastic, Debian Edu seems to
  75 be made of steel.</p>
  76
  77 <p><strong>What do you see as the disadvantages of Skolelinux / Debian
  78 Edu?</strong></p>
  79
  80 <p>I found two main disadvantages.</p>
  81
  82 <p>I'm not an expert but I've got notions and I had to spent a considerable
  83 amount of time trying to bring up a standard network topology. I'm quite
  84 stubborn and I just worked until I did but I'm sure many people with few
  85 resources (not big schools, but academies for example) would have switched
  86 or dropped.</p>
  87
  88 <p>It's amazing how such a complex system like Debian Edu has achieved
  89 this out-of-the-box state. Even though tweaking without breaking gets
  90 more difficult, as more factors have to be considered. This can
  91 discourage many people too.</p>
  92
  93 <p><strong>Which free software do you use daily?</strong></p>
  94
  95 <p>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
  96 Virtualbox.</p>
  97
  98
  99 <p><strong>Which strategy do you believe is the right one to use to
 100 get schools to use free software?</strong></p>
 101
 102 <p>I don't think there is a need for a particular strategy. The free
 103 attribute in both "freedom" and "no price" meanings is what will
 104 really bring free software to schools. In my experience I can think of
 105 the <a href="http://www.r-project.org/">"R" statistical language</a>; a
 106 few years a ago was an extremely nerd tool for university people.
 107 Today it's being increasingly used to teach statistics at many
 108 different level of studies.  I believe free and open software will
 109 increasingly gain popularity, but I'm sure schools will be one of the
 110 first scenarios where this will happen.</p>

 131         <p><a href="http://www.nuug.no/">Foreningen NUUG</a> melder i natt at
 132 NRK nå har bestemt seg for
 133 <a href="http://www.nuug.no/news/NRK_viser_filmen_om_Datalagringsdirektivet_f_rste_gang_2014_03_31.shtml">når
 134 den norske dokumentarfilmen om datalagringsdirektivet skal
 135 sendes</a> (se <a href="http://www.imdb.com/title/tt2832844/">IMDB</a>
 136 for detaljer om filmen) . Første visning blir på NRK2 mandag
 137 2014-03-31 kl. 19:50, og deretter visninger onsdag 2014-04-02
 138 kl. 12:30, fredag 2014-04-04 kl. 19:40 og søndag 2014-04-06 kl. 15:10.
 139 Jeg har sett dokumentaren, og jeg anbefaler enhver å se den selv.  Som
 140 oppvarming mens vi venter anbefaler jeg Bjørn Stærks kronikk i
 141 Aftenposten fra i går,
 142 <a href="http://www.aftenposten.no/meninger/kronikker/Autoritar-gjokunge-7514915.html">Autoritær
 143 gjøkunge</a>, der han gir en grei skisse av hvor ille det står til med
 144 retten til privatliv og beskyttelsen av demokrati i Norge og resten
 145 verden, og helt riktig slår fast at det er vi i databransjen som
 146 sitter med nøkkelen til å gjøre noe med dette.  Jeg har involvert meg
 147 i prosjektene <a href="http://www.dugnadsnett.no/">dugnadsnett.no</a>
 148 og <a href="https://wiki.debian.org/FreedomBox">FreedomBox</a> for å
 149 forsøke å gjøre litt selv for å bedre situasjonen, men det er mye
 150 hardt arbeid fra mange flere enn meg som gjenstår før vi kan sies å ha
 151 gjenopprettet balansen.</p>
 152
 153 <p>Jeg regner med at nettutgaven dukker opp på
 154 <a href="http://tv.nrk.no/program/koid75005313/tema-dine-digitale-spor-datalagringsdirektivet">NRKs
 155 side om filmen om datalagringsdirektivet</a> om fem dager.  Hold et
 156 øye med siden, og tips venner og slekt om at de også bør se den.</p>

 177         <p>Did you ever need to store logs or other files in a way that would
 178 allow it to be used as evidence in court, and needed a way to
 179 demonstrate without reasonable doubt that the file had not been
 180 changed since it was created?  Or, did you ever need to document that
 181 a given document was received at some point in time, like some
 182 archived document or the answer to an exam, and not changed after it
 183 was received?  The problem in these settings is to remove the need to
 184 trust yourself and your computers, while still being able to prove
 185 that a file is the same as it was at some given time in the past.</p>
 186
 187 <p>A solution to these problems is to have a trusted third party
 188 "stamp" the document and verify that at some given time the document
 189 looked a given way.  Such
 190 <a href="https://en.wikipedia.org/wiki/Notarius">notarius</a> service
 191 have been around for thousands of years, and its digital equivalent is
 192 called a
 193 <a href="http://en.wikipedia.org/wiki/Trusted_timestamping">trusted
 194 timestamping service</a>.  <a href="http://www.ietf.org/">The Internet
 195 Engineering Task Force</a> standardised how such service could work a
 196 few years ago as <a href="http://tools.ietf.org/html/rfc3161">RFC
 197 3161</a>.  The mechanism is simple.  Create a hash of the file in
 198 question, send it to a trusted third party which add a time stamp to
 199 the hash and sign the result with its private key, and send back the
 200 signed hash + timestamp.  Both email, FTP and HTTP can be used to
 201 request such signature, depending on what is provided by the service
 202 used. Anyone with the document and the signature can then verify that
 203 the document matches the signature by creating their own hash and
 204 checking the signature using the trusted third party public key.
 205 There are several commercial services around providing such
 206 timestamping.  A quick search for
 207 "<a href="https://duckduckgo.com/?q=rfc+3161+service">rfc 3161
 208 service</a>" pointed me to at least
 209 <a href="https://www.digistamp.com/technical/how-a-digital-time-stamp-works/">DigiStamp</a>,
 210 <a href="http://www.quovadisglobal.co.uk/CertificateServices/SigningServices/TimeStamp.aspx">Quo
 211 Vadis</a>,
 212 <a href="https://www.globalsign.com/timestamp-service/">Global Sign</a>
 213 and <a href="http://www.globaltrustfinder.com/TSADefault.aspx">Global
 214 Trust Finder</a>.  The system work as long as the private key of the
 215 trusted third party is not compromised.</p>
 216
 217 <p>But as far as I can tell, there are very few public trusted
 218 timestamp services available for everyone.  I've been looking for one
 219 for a while now. But yesterday I found one over at
 220 <a href="https://www.pki.dfn.de/zeitstempeldienst/">Deutches
 221 Forschungsnetz</a> mentioned in
 222 <a href="http://www.d-mueller.de/blog/dealing-with-trusted-timestamps-in-php-rfc-3161/">a
 223 blog by David Müller</a>.  I then found
 224 <a href="http://www.rz.uni-greifswald.de/support/dfn-pki-zertifikate/zeitstempeldienst.html">a
 225 good recipe on how to use the service</a> over at the University of
 226 Greifswald.</p>
 227
 228 <p><a href="http://www.openssl.org/">The OpenSSL library</a> contain
 229 both server and tools to use and set up your own signing service.  See
 230 the ts(1SSL), tsget(1SSL) manual pages for more details.  The
 231 following shell script demonstrate how to extract a signed timestamp
 232 for any file on the disk in a Debian environment:</p>
 233
 234 <p><blockquote><pre>
 235 #!/bin/sh
 236 set -e
 237 url="http://zeitstempel.dfn.de"
 238 caurl="https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt"
 239 reqfile=$(mktemp -t tmp.XXXXXXXXXX.tsq)
 240 resfile=$(mktemp -t tmp.XXXXXXXXXX.tsr)
 241 cafile=chain.txt
 242 if [ ! -f $cafile ] ; then
 243     wget -O $cafile "$caurl"
 244 fi
 245 openssl ts -query -data "$1" -cert | tee "$reqfile" \
 246     | /usr/lib/ssl/misc/tsget -h "$url" -o "$resfile"
 247 openssl ts -reply -in "$resfile" -text 1>&2
 248 openssl ts -verify -data "$1" -in "$resfile" -CAfile "$cafile" 1>&2
 249 base64 < "$resfile"
 250 rm "$reqfile" "$resfile"
 251 </pre></blockquote></p>
 252
 253 <p>The argument to the script is the file to timestamp, and the output
 254 is a base64 encoded version of the signature to STDOUT and details
 255 about the signature to STDERR.  Note that due to
 256 <a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=742553">a bug
 257 in the tsget script</a>, you might need to modify the included script
 258 and remove the last line.  Or just write your own HTTP uploader using
 259 curl. :) Now you too can prove and verify that files have not been
 260 changed.</p>
 261
 262 <p>But the Internet need more public trusted timestamp services.
 263 Perhaps something for <a href="http://www.uninett.no/">Uninett</a> or
 264 my work place the <a href="http://www.uio.no/">University of Oslo</a>
 265 to set up?</p>

 286         <p>Keeping your DVD collection safe from scratches and curious
 287 children fingers while still having it available when you want to see a
 288 movie is not straight forward.  My preferred method at the moment is
 289 to store a full copy of the ISO on a hard drive, and use VLC, Popcorn
 290 Hour or other useful players to view the resulting file.  This way the
 291 subtitles and bonus material are still available and using the ISO is
 292 just like inserting the original DVD record in the DVD player.</p>
 293
 294 <p>Earlier I used dd for taking security copies, but it do not handle
 295 DVDs giving read errors (which are quite a few of them).  I've also
 296 tried using
 297 <a href="http://people.skolelinux.org/pere/blog/Ripping_problematic_DVDs_using_dvdbackup_and_genisoimage.html">dvdbackup
 298 and genisoimage</a>, but these days I use the marvellous python library
 299 and program
 300 <a href="http://bblank.thinkmo.de/blog/new-software-python-dvdvideo">python-dvdvideo</a>
 301 written by Bastian Blank.  It is
 302 <a href="http://packages.qa.debian.org/p/python-dvdvideo.html">in Debian
 303 already</a> and the binary package name is python3-dvdvideo. Instead
 304 of trying to read every block from the DVD, it parses the file
 305 structure and figure out which block on the DVD is actually in used,
 306 and only read those blocks from the DVD.  This work surprisingly well,
 307 and I have been able to almost backup my entire DVD collection using
 308 this method.</p>
 309
 310 <p>So far, python-dvdvideo have failed on between 10 and
 311 20 DVDs, which is a small fraction of my collection.  The most common
 312 problem is
 313 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831">DVDs
 314 using UTF-16 instead of UTF-8 characters</a>, which according to
 315 Bastian is against the DVD specification (and seem to cause some
 316 players to fail too).  A rarer problem is what seem to be inconsistent
 317 DVD structures, as the python library
 318 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim
 319 there is a overlap between objects</a>.  An equally rare problem claim
 320 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878">some
 321 value is out of range</a>.  No idea what is going on there.  I wish I
 322 knew enough about the DVD format to fix these, to ensure my movie
 323 collection will stay with me in the future.</p>
 324
 325 <p>So, if you need to keep your DVDs safe, back them up using
 326 python-dvdvideo. :)</p>

 347         <p>Det offentlige Norge har mye kunnskap og informasjon.  Men hvordan
 348 kan en få tilgang til den på en enkel måte?  Takket være et lite
 349 knippe lover og tilhørende forskrifter, blant annet
 350 <a href="http://lovdata.no/dokument/NL/lov/2006-05-19-16">offentlighetsloven</a>,
 351 <a href="http://lovdata.no/dokument/NL/lov/2003-05-09-31">miljøinformasjonsloven</a>
 352 og
 353 <a href="http://lovdata.no/dokument/NL/lov/1967-02-10/">forvaltningsloven</a>
 354 har en rett til å spørre det offentlige og få svar.  Men det finnes
 355 intet offentlig arkiv over hva andre har spurt om, og dermed risikerer en
 356 å måtte forstyrre myndighetene gang på gang for å få tak i samme
 357 informasjonen på nytt.  <a href="http://www.mysociety.org/">Britiske
 358 mySociety</a> har laget tjenesten
 359 <a href="http://www.whatdotheyknow.com/">WhatDoTheyKnow</a> som gjør
 360 noe med dette.  I Storbritannia blir WhatdoTheyKnow brukt i
 361 <a href="http://www.mysociety.org/2011/07/01/whatdotheyknows-share-of-central-government-foi-requests-q2-2011/">ca
 362 15% av alle innsynsforespørsler mot sentraladministrasjonen</a>.
 363 Prosjektet heter <a href="http://www.alaveteli.org/">Alaveteli</A>, og
 364 er takk i bruk en rekke steder etter at løsningen ble generalisert og
 365 gjort mulig å oversette.  Den hjelper borgerne med å be om innsyn,
 366 rådgir ved purringer og klager og lar alle se hvilke henvendelser som
 367 er sendt til det offentlige og hvilke svar som er kommet inn, i et
 368 søkpart arkiv.  Her i Norge holder vi i foreningen NUUG på å få opp en
 369 norsk utgave av Alaveteli, og her trenger vi din hjelp med
 370 oversettelsen.</p>
 371
 372 <p>Så langt er 76 % av Alaveteli oversatt til norsk bokmål, men vi
 373 skulle gjerne vært oppe i 100 % før lansering.  Oversettelsen gjøres
 374 på <a href="https://www.transifex.com/projects/p/alaveteli/">Transifex,
 375 der enhver som registrerer seg</a> og ber om tilgang til
 376 bokmålsoversettelsen får bidra.  Vi har satt opp en test av tjenesten
 377 (som ikke sender epost til det offentlige, kun til oss som holder på å
 378 sette opp tjenesten) på maskinen
 379 <a href="http://alaveteli-dev.nuug.no/">alaveteli-dev.nuug.no</a>, der
 380 en kan se hvordan de oversatte meldingen blir seende ut på nettsiden.

 410         <p>The <a href="https://wiki.debian.org/FreedomBox">Freedombox
 411 project</a> is working on providing the software and hardware for
 412 making it easy for non-technical people to host their data and
 413 communication at home, and being able to communicate with their
 414 friends and family encrypted and away from prying eyes.  It has been
 415 going on for a while, and is slowly progressing towards a new test
 416 release (0.2).</p>
 417
 418 <p>And what day could be better than the Pi day to announce that the
 419 new version will provide "hard drive" / SD card / USB stick images for
 420 Dreamplug, Raspberry Pi and VirtualBox (or any other virtualization
 421 system), and can also be installed using a Debian installer preseed
 422 file.  The Debian based Freedombox is now based on Debian Jessie,
 423 where most of the needed packages used are already present.  Only one,
 424 the freedombox-setup package, is missing.  To try to build your own
 425 boot image to test the current status, fetch the freedom-maker scripts
 426 and build using
 427 <a href="http://packages.qa.debian.org/vmdebootstrap">vmdebootstrap</a>
 428 with a user with sudo access to become root:
 429
 430 <pre>
 431 git clone http://anonscm.debian.org/git/freedombox/freedom-maker.git \
 432   freedom-maker
 433 sudo apt-get install git vmdebootstrap mercurial python-docutils \
 434   mktorrent extlinux virtualbox qemu-user-static binfmt-support \
 435   u-boot-tools
 436 make -C freedom-maker dreamplug-image raspberry-image virtualbox-image
 437 </pre>
 438
 439 <p>Root access is needed to run debootstrap and mount loopback
 440 devices.  See the README for more details on the build. If you do not
 441 want all three images, trim the make line.  But note that thanks to <a
 442 href="https://bugs.debian.org/741407">a race condition in
 443 vmdebootstrap</a>, the build might fail without the patch to the
 444 kpartx call.</p>
 445
 446 <p>If you instead want to install using a Debian CD and the preseed
 447 method, boot a Debian Wheezy ISO and use this boot argument to load
 448 the preseed values:</p>
 449
 450 <pre>
 451 url=<a href="http://www.reinholdtsen.name/freedombox/preseed-jessie.dat">http://www.reinholdtsen.name/freedombox/preseed-jessie.dat</a>
 452 </pre>
 453
 454 <p>But note that due to <a href="https://bugs.debian.org/740673">a
 455 recently introduced bug in apt in Jessie</a>, the installer will
 456 currently hang while setting up APT sources.  Killing the
 457 '<tt>apt-cdrom ident</tt>' process when it hang a few times during the
 458 installation will get the installation going.  This affect all
 459 installations in Jessie, and I expect it will be fixed soon.</p>
 460
 461 <p>Give it a go and let us know how it goes on the mailing list, and help
 462 us get the new release published. :) Please join us on

 486       <div class="body">
 487         <p>On larger sites, it is useful to use a dedicated storage server for
 488 storing user home directories and data.  The design for handling this
 489 in <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, is
 490 to update the automount rules in LDAP and let the automount daemon on
 491 the clients take care of the rest.  I was reminded about the need to
 492 document this better when one of the customers of
 493 <a href="http://www.slxdrift.no/">Skolelinux Drift AS</a>, where I am
 494 on the board of directors, asked about how to do this.  The steps to
 495 get this working are the following:</p>
 496
 497 <p><ol>
 498
 499 <li>Add new storage server in DNS.  I use nas-server.intern as the
 500 example host here.</li>
 501
 502 <li>Add automoun LDAP information about this server in LDAP, to allow
 503 all clients to automatically mount it on reqeust.</li>
 504
 505 <li>Add the relevant entries in tjener.intern:/etc/fstab, because
 506 tjener.intern do not use automount to avoid mounting loops.</li>
 507
 508 </ol></p>
 509
 510 <p>DNS entries are added in GOsa², and not described here.  Follow the
 511 <a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted">instructions
 512 in the manual</a> (Machine Management with GOsa² in section Getting
 513 started).</p>
 514
 515 <p>Ensure that the NFS export points on the server are exported to the
 516 relevant subnets or machines:</p>
 517
 518 <p><blockquote><pre>
 519 root@tjener:~# showmount -e nas-server
 520 Export list for nas-server:
 521 /storage         10.0.0.0/8
 522 root@tjener:~#
 523 </pre></blockquote></p>
 524
 525 <p>Here everything on the backbone network is granted access to the
 526 /storage export.  With NFSv3 it is slightly better to limit it to
 527 netgroup membership or single IP addresses to have some limits on the
 528 NFS access.</p>
 529
 530 <p>The next step is to update LDAP.  This can not be done using GOsa²,
 531 because it lack a module for automount.  Instead, use ldapvi and add
 532 the required LDAP objects using an editor.</p>
 533
 534 <p><blockquote><pre>
 535 ldapvi --ldap-conf -ZD '(cn=admin)' -b ou=automount,dc=skole,dc=skolelinux,dc=no
 536 </pre></blockquote></p>
 537
 538 <p>When the editor show up, add the following LDAP objects at the
 539 bottom of the document.  The "/&" part in the last LDAP object is a
 540 wild card matching everything the nas-server exports, removing the
 541 need to list individual mount points in LDAP.</p>
 542
 543 <p><blockquote><pre>
 544 add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no
 545 objectClass: automount
 546 cn: nas-server
 547 automountInformation: -fstype=autofs --timeout=60 ldap:ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
 548
 549 add ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
 550 objectClass: top
 551 objectClass: automountMap
 552 ou: auto.nas-server
 553
 554 add cn=/,ou=auto.nas-server,ou=automount,dc=skole,dc=skolelinux,dc=no
 555 objectClass: automount
 556 cn: /
 557 automountInformation: -fstype=nfs,tcp,rsize=32768,wsize=32768,rw,intr,hard,nodev,nosuid,noatime nas-server.intern:/&
 558 </pre></blockquote></p>
 559
 560 <p>The last step to remember is to mount the relevant mount points in
 561 tjener.intern by adding them to /etc/fstab, creating the mount
 562 directories using mkdir and running "mount -a" to mount them.</p>
 563
 564 <p>When this is done, your users should be able to access the files on
 565 the storage server directly by just visiting the
 566 /tjener/nas-server/storage/ directory using any application on any
 567 workstation, LTSP client or LTSP server.</p>

 585          7th March 2014
 586       </div>
 587       <div class="body">
 588         <p>For noen uker siden ble NXCs fri programvarelisenserte
 589 NOARK5-løsning
 590 <a href="http://www.nuug.no/aktiviteter/20140211-noark/">presentert hos
 591 NUUG</a> (video
 592 <a href="https://www.youtube.com/watch?v=JCb_dNS3MHQ">på youtube
 593 foreløbig</a>), og det fikk meg til å titte litt mer på NOARK5,
 594 standarden for arkivhåndtering i det offentlige Norge.  Jeg lurer på
 595 om denne kjernen kan være nyttig i et par av mine prosjekter, og for ett
 596 av dem er det mest aktuelt å lagre epost.  Jeg klarte ikke finne noen
 597 anbefaling om hvordan RFC 822-formattert epost (aka Internett-epost)
 598 burde lagres i NOARK5, selv om jeg vet at noen arkiver tar
 599 PDF-utskrift av eposten med sitt epostprogram og så arkiverer PDF-en
 600 (eller enda værre, tar papirutskrift og lagrer bildet av eposten som
 601 PDF i arkivet).</p>
 602
 603 <p>Det er ikke så mange formater som er akseptert av riksarkivet til
 604 langtidsoppbevaring av offentlige arkiver, og PDF og XML er de mest
 605 aktuelle i så måte.  Det slo meg at det måtte da finnes en eller annen
 606 egnet XML-representasjon og at det kanskje var enighet om hvilken som
 607 burde brukes, så jeg tok mot til meg og spurte
 608 <a href="http://samdok.com/">SAMDOK</a>, en gruppe tilknyttet
 609 arkivverket som ser ut til å jobbe med NOARK-samhandling, om de hadde
 610 noen anbefalinger:
 611
 612 <p><blockquote>
 613 <p>Hei.</p>
 614
 615 <p>Usikker på om dette er riktig forum å ta opp mitt spørsmål, men jeg
 616 lurer på om det er definert en anbefaling om hvordan RFC
 617 822-formatterte epost (aka vanlig Internet-epost) bør lages håndteres
 618 i NOARK5, slik at en bevarer all informasjon i eposten
 619 (f.eks. Received-linjer).  Finnes det en anbefalt XML-mapping ala den
 620 som beskrives på
 621 &lt;URL: <a href="https://www.informit.com/articles/article.aspx?p=32074">https://www.informit.com/articles/article.aspx?p=32074</a> &gt;?  Mitt
 622 mål er at det skal være mulig å lagre eposten i en NOARK5-kjerne og
 623 kunne få ut en identisk formattert kopi av opprinnelig epost ved
 624 behov.</p>
 625 </blockquote></p>
 626
 627 <p>Postmottaker hos SAMDOK mente spørsmålet heller burde stilles
 628 direkte til riksarkivet, og jeg fikk i dag svar derfra formulert av
 629 seniorrådgiver Geir Ivar Tungesvik:</p>
 630
 631 <p><blockquote>
 632 <p>Riksarkivet har ingen anbefalinger når det gjelder konvertering fra
 633 e-post til XML.  Det står arkivskaper fritt å eventuelt definere/bruke
 634 eget format.  Inklusive da - som det spørres om - et format der det er
 635 mulig å re-etablere e-post format ut fra XML-en.  XML (e-post)
 636 dokumenter må være referert i arkivstrukturen, og det må vedlegges et
 637 gyldig XML skjema (.xsd) for XML-filene. Arkivskaper står altså fritt
 638 til å gjøre hva de vil, bare det dokumenteres og det kan dannes et
 639 utrekk ved avlevering til depot.</p>
 640
 641 <p>De obligatoriske kravene i Noark 5 standarden må altså oppfylles -
 642 etter dialog med Riksarkivet i forbindelse med godkjenning. For
 643 offentlige arkiv er det særlig viktig med filene loependeJournal.xml
 644 og offentligJournal.xml. Private arkiv som vil forholde seg til Noark
 645 5 standarden er selvsagt frie til å bruke det som er relevant for dem
 646 av obligatoriske krav.</p>
 647 </blockquote></p>
 648
 649 <p>Det ser dermed ut for meg som om det er et lite behov for å
 650 standardisere XML-lagring av RFC-822-formatterte meldinger.  Noen som
 651 vet om god spesifikasjon i så måte?  I tillegg til den omtalt over,
 652 har jeg kommet over flere aktuelle beskrivelser (søk på "rfc 822
 653 xml", så finner du aktuelle alternativer).</p>
