  14                 <description>&lt;p&gt;It is pleasing to see that the work we put down in publishing new
  15 editions of the classic &lt;a href=&quot;http://www.free-culture.cc/&quot;&gt;Free
  16 Culture book&lt;/a&gt; by the founder of the Creative Commons movement,
  17 Lawrence Lessig, is still being appreciated.  I had a look at the
  18 latest sales numbers for the paper edition today.  Not too impressive,
  19 but some buyers still exist.  All the revenue from the books are sent
  20 to the &lt;a href=&quot;https://creativecommons.org/&quot;&gt;Creative Commons
  21 Corporation&lt;/a&gt;, and they receive the largest cut if you buy directly
  22 from Lulu.  Most books are sold via Amazon, with Ingram second and
  23 only a small fraction directly from Lulu.  The ebook edition is
  24 available for free from
  25 &lt;a href=&quot;https://github.com/petterreinholdtsen/free-culture-lessig&quot;&gt;Github&lt;/a&gt;.&lt;/p&gt;

  57 &lt;/tr&gt;
  58
  59 &lt;/table&gt;
  60
  61 &lt;p&gt;A bit sad to see the low sales number on the Norwegian edition, and
  62 a bit surprising the English edition still selling so well.&lt;/p&gt;
  63
  64 &lt;p&gt;If you would like to translate and publish the book in your native
  65 language, I would be happy to help make it happen.  Please get in
  66 touch.&lt;/p&gt;

  74                 <pubDate>Sat, 10 Jun 2017 00:40:00 +0200</pubDate>

  86    correspondencepartInternal&lt;/li&gt;
  87  &lt;li&gt;Applied for coverity coverage and started submitting code on
  88    regualr basis.&lt;/li&gt;
  89  &lt;li&gt;Started fixing bugs reported by coverity&lt;/li&gt;
  90  &lt;li&gt;Corrected and completed HATEOAS links to make sure entire API is

  92  &lt;li&gt;Corrected all relation URLs to use trailing slash.&lt;/li&gt;
  93  &lt;li&gt;Add initial support for storing data in ElasticSearch.&lt;/li&gt;
  94  &lt;li&gt;Now able to receive and store uploaded files in the archive.&lt;/li&gt;
  95  &lt;li&gt;Changed JSON output for object lists to have relations in _links.&lt;/li&gt;
  96  &lt;li&gt;Improve JSON output for empty object lists.&lt;/li&gt;
  97  &lt;li&gt;Now uses correct MIME type application/vnd.noark5-v4+json.&lt;/li&gt;
  98  &lt;li&gt;Added support for docker container images.&lt;/li&gt;
  99  &lt;li&gt;Added simple API browser implemented in JavaScript/Angular.&lt;/li&gt;
 100  &lt;li&gt;Started on archive client implemented in JavaScript/Angular.&lt;/li&gt;
 101  &lt;li&gt;Started on prototype to show the public mail journal.&lt;/li&gt;
 102  &lt;li&gt;Improved performance by disabling Sprint FileWatcher.&lt;/li&gt;
 103  &lt;li&gt;Added support for &#39;arkivskaper&#39;, &#39;saksmappe&#39; and &#39;journalpost&#39;.&lt;/li&gt;

 105  &lt;li&gt;Added support for Cross-origin resource sharing (CORS).&lt;/li&gt;
 106  &lt;li&gt;Changed login method from Basic Auth to JSON Web Token (RFC 7519)
 107    style.&lt;/li&gt;
 108  &lt;li&gt;Added support for GET-ing ny-* URLs.&lt;/li&gt;
 109  &lt;li&gt;Added support for modifying entities using PUT and eTag.&lt;/li&gt;
 110  &lt;li&gt;Added support for returning XML output on request.&lt;/li&gt;
 111  &lt;li&gt;Removed support for English field and class names, limiting ourself
 112    to the official names.&lt;/li&gt;
 113  &lt;li&gt;...&lt;/li&gt;
 114
 115 &lt;/ul&gt;

 125                 <title>Idea for storing trusted timestamps in a Noark 5 archive</title>
 126                 <link>http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html</link>
 127                 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html</guid>
 128                 <pubDate>Wed, 7 Jun 2017 21:40:00 +0200</pubDate>
 129                 <description>&lt;p&gt;&lt;em&gt;This is a copy of
 130 &lt;a href=&quot;https://lists.nuug.no/pipermail/nikita-noark/2017-June/000297.html&quot;&gt;an
 131 email I posted to the nikita-noark mailing list&lt;/a&gt;.  Please follow up
 132 there if you would like to discuss this topic.  The background is that
 133 we are making a free software archive system based on the Norwegian
 134 &lt;a href=&quot;https://www.arkivverket.no/forvaltning-og-utvikling/regelverk-og-standarder/noark-standarden&quot;&gt;Noark
 135 5 standard&lt;/a&gt; for government archives.&lt;/em&gt;&lt;/p&gt;
 136
 137 &lt;p&gt;I&#39;ve been wondering a bit lately how trusted timestamps could be
 138 stored in Noark 5.
 139 &lt;a href=&quot;https://en.wikipedia.org/wiki/Trusted_timestamping&quot;&gt;Trusted
 140 timestamps&lt;/a&gt; can be used to verify that some information
 141 (document/file/checksum/metadata) have not been changed since a
 142 specific time in the past.  This is useful to verify the integrity of
 143 the documents in the archive.&lt;/p&gt;
 144
 145 &lt;p&gt;Then it occured to me, perhaps the trusted timestamps could be
 146 stored as dokument variants (ie dokumentobjekt referered to from
 147 dokumentbeskrivelse) with the filename set to the hash it is
 148 stamping?&lt;/p&gt;
 149
 150 &lt;p&gt;Given a &quot;dokumentbeskrivelse&quot; with an associated &quot;dokumentobjekt&quot;,
 151 a new dokumentobjekt is associated with &quot;dokumentbeskrivelse&quot; with the
 152 same attributes as the stamped dokumentobjekt except these
 153 attributes:&lt;/p&gt;
 154
 155 &lt;ul&gt;
 156
 157 &lt;li&gt;format -&gt; &quot;RFC3161&quot;
 158 &lt;li&gt;mimeType -&gt; &quot;application/timestamp-reply&quot;
 159 &lt;li&gt;formatDetaljer -&gt; &quot;&amp;lt;source URL for timestamp service&amp;gt;&quot;
 160 &lt;li&gt;filenavn -&gt; &quot;&amp;lt;sjekksum&amp;gt;.tsr&quot;
 161
 162 &lt;/ul&gt;
 163
 164 &lt;p&gt;This assume a service following
 165 &lt;a href=&quot;https://tools.ietf.org/html/rfc3161&quot;&gt;IETF RFC 3161&lt;/a&gt; is
 166 used, which specifiy the given MIME type for replies and the .tsr file
 167 ending for the content of such trusted timestamp.  As far as I can
 168 tell from the Noark 5 specifications, it is OK to have several
 169 variants/renderings of a dokument attached to a given
 170 dokumentbeskrivelse objekt.  It might be stretching it a bit to make
 171 some of these variants represent crypto-signatures useful for
 172 verifying the document integrity instead of representing the dokument
 173 itself.&lt;/p&gt;
 174
 175 &lt;p&gt;Using the source of the service in formatDetaljer allow several
 176 timestamping services to be used.  This is useful to spread the risk
 177 of key compromise over several organisations.  It would only be a
 178 problem to trust the timestamps if all of the organisations are
 179 compromised.&lt;/p&gt;
 180
 181 &lt;p&gt;The following oneliner on Linux can be used to generate the tsr
 182 file.  $input is the path to the file to checksum, and $sha256 is the
 183 SHA-256 checksum of the file (ie the &quot;&lt;sjekksum&gt;.tsr&quot; value mentioned
 184 above).&lt;/p&gt;
 185
 186 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 187 openssl ts -query -data &quot;$inputfile&quot; -cert -sha256 -no_nonce \
 188   | curl -s -H &quot;Content-Type: application/timestamp-query&quot; \
 189       --data-binary &quot;@-&quot; http://zeitstempel.dfn.de &gt; $sha256.tsr
 190 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 191
 192 &lt;p&gt;To verify the timestamp, you first need to download the public key
 193 of the trusted timestamp service, for example using this command:&lt;/p&gt;
 194
 195 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 196 wget -O ca-cert.txt \
 197   https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
 198 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 199
 200 &lt;p&gt;Note, the public key should be stored alongside the timestamps in
 201 the archive to make sure it is also available 100 years from now.  It
 202 is probably a good idea to standardise how and were to store such
 203 public keys, to make it easier to find for those trying to verify
 204 documents 100 or 1000 years from now. :)&lt;/p&gt;
 205
 206 &lt;p&gt;The verification itself is a simple openssl command:&lt;/p&gt;
 207
 208 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
 209 openssl ts -verify -data $inputfile -in $sha256.tsr \
 210   -CAfile ca-cert.txt -text
 211 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
 212
 213 &lt;p&gt;Is there any reason this approach would not work?  Is it somehow against
 214 the Noark 5 specification?&lt;/p&gt;

 220                 <link>http://people.skolelinux.org/pere/blog/N_r_nynorskoversettelsen_svikter_til_eksamen___.html</link>

 222                 <pubDate>Sat, 3 Jun 2017 08:20:00 +0200</pubDate>
 223                 <description>&lt;p&gt;&lt;a href=&quot;http://www.aftenposten.no/norge/Krever-at-elever-ma-fa-annullert-eksamen-etter-rot-med-oppgavetekster-622459b.html&quot;&gt;Aftenposten
 224 melder i dag&lt;/a&gt; om feil i eksamensoppgavene for eksamen i politikk og
 225 menneskerettigheter, der teksten i bokmåls og nynorskutgaven ikke var
 226 like.  Oppgaveteksten er gjengitt i artikkelen, og jeg ble nysgjerring
 227 på om den fri oversetterløsningen
 228 &lt;a href=&quot;https://www.apertium.org/&quot;&gt;Apertium&lt;/a&gt; ville gjort en bedre
 229 jobb enn Utdanningsdirektoratet.  Det kan se slik ut.&lt;/p&gt;
 230
 231 &lt;p&gt;Her er bokmålsoppgaven fra eksamenen:&lt;/p&gt;
 232
 233 &lt;blockquote&gt;
 234 &lt;p&gt;Drøft utfordringene knyttet til nasjonalstatenes og andre aktørers
 235 rolle og muligheter til å håndtere internasjonale utfordringer, som
 236 for eksempel flykningekrisen.&lt;/p&gt;
 237
 238 &lt;p&gt;Vedlegge er eksempler på tekster som kan gi relevante perspektiver
 239 på temaet:&lt;/p&gt;
 240 &lt;ol&gt;
 241 &lt;li&gt;Flykningeregnskapet 2016, UNHCR og IDMC
 242 &lt;li&gt;«Grenseløst Europa for fall» A-Magasinet, 26. november 2015
 243 &lt;/ol&gt;
 244
 245 &lt;/blockquote&gt;
 246
 247 &lt;p&gt;Dette oversetter Apertium slik:&lt;/p&gt;
 248
 249 &lt;blockquote&gt;
 250 &lt;p&gt;Drøft utfordringane knytte til nasjonalstatane sine og rolla til
 251 andre aktørar og høve til å handtera internasjonale utfordringar, som
 252 til dømes *flykningekrisen.&lt;/p&gt;
 253
 254 &lt;p&gt;Vedleggja er døme på tekster som kan gje relevante perspektiv på
 255 temaet:&lt;/p&gt;
 256
 257 &lt;ol&gt;
 258 &lt;li&gt;*Flykningeregnskapet 2016, *UNHCR og *IDMC&lt;/li&gt;
 259 &lt;li&gt;«*Grenseløst Europa for fall» A-Magasinet, 26. november 2015&lt;/li&gt;
 260 &lt;/ol&gt;
 261
 262 &lt;/blockquote&gt;
 263
 264 &lt;p&gt;Ord som ikke ble forstått er markert med stjerne (*), og trenger
 265 ekstra språksjekk.  Men ingen ord er forsvunnet, slik det var i
 266 oppgaven elevene fikk presentert på eksamen.  Jeg mistenker dog at
 267 &quot;andre aktørers rolle og muligheter til ...&quot; burde vært oversatt til
 268 &quot;rolla til andre aktørar og deira høve til ...&quot; eller noe slikt, men
 269 det er kanskje flisespikking.  Det understreker vel bare at det alltid
 270 trengs korrekturlesning etter automatisk oversettelse.&lt;/p&gt;
