As an example, we use a fictitious language with code "xx" and Wikipedia rank 44.

Note: more code changes will be needed for the first language code that contains a dash "-". Please update this guide.


Get language code and rank

Get the wiki language code and rank from http://s23.org/wikistats/wikipedias_html.php

namespace number: multiply the rank by 2 and add 200

talk namespace number: add 1 to the namespace number

Example: language code "xx", rank 44, namespace number 288, talk namespace number 289

CAUTION: If the calculated namespace number already exists for another language (because the ranking has changed) do not change the existing namespace number. Please find a neighboring or close enough number that works.

If 288 is in use, we choose other numbers, let's say 298 and 299.


Update the extraction framework

Edit core/org.dbpedia.extraction.wikiparser.Namespace.scala

Edit core/org.dbpedia.extraction.wikiparser.Namespace.scala. Add something like this at the appropriate position:

"xx"->288

Edit dump/extract.default.properties

Edit dump/extract.default.properties. Add something like this at the appropriate position:

extractors.xx=MappingExtractor

Commit changes

Commit and push the changes to default branch.

Update and restart the mapping server

Log onto the machine that's serving http://mappings.dbpedia.org/server/ URLs.

Stop the server:

ps axfu | grep java

Look for class ...server.Server, and then:

kill <process id>

Then update, compile and start the server:

cd /home/dbpedia-server/dbpedia/extraction_framework
hg pull
hg update
mvn clean install --projects core,server
cd server
../run server &>server-<YYYY>-<MM>-<DD>.01.log &


Update mappings wiki

Update the MediaWiki settings

Log onto the machine that is serving http://mappings.dbpedia.org/index.php URLs.

Open htdocs/mappings/LocalSettings.php

Add the following line at the right position in the code:

"xx" => 288

Restart the Apache server.

Edit mappings wiki sidebar

Edit MediaWiki:Sidebar. Add a link for the new language:

** {{fullurl:Special:AllPages|namespace=288}}|Mappings (xx)

Edit DBpedia datasets

e) generate statistics for new language run RedirectExtractor, InfoboxExtractor, TemplateParameterExtractor (see dump/extraction.server.properties) run CreateMappingStats (launcher ‘stats’ in server/pom.xml) copy src/main/statistics/mappingstatistics_bg.txt to same folder on server Update and deploy sprint stuff.
