Hi Merlijn, these updates are normaly made by /maintenance/update_namespaces.py bot script which calls the namespace via api. I've modified that script to be able dealing with all namespace aliases too. Anyway the order of ja: namespace and namespace alias has been changed and there is a difference between ja-wiki (1) and other projects like ja-wikinews (2). This caused me to change the family.py in r8236 as default (3) which has valid namespace aliases for all related mediawiki families in the right order (<namespace> first, <namespacealiases> behind in that list) and to override it in wikipedia_family (4). I do recommend not to change the family.py but the related wikia family file. Otherwise all mediawiki family files must have these override assignments you can find in wikipedia_family.py now. (1) look at http://ja.wikipedia.org/w/api.php?action=query&meta=siteinfo&siprop… (2) look at http://ja.wikinews.org/w/api.php?action=query&meta=siteinfo&siprop=… (3) http://svn.wikimedia.org/viewvc/pywikipedia/trunk/pywikipedia/family.py?r1=… (4) http://svn.wikimedia.org/viewvc/pywikipedia/trunk/pywikipedia/families/wiki… I hope this explanation was understandable.
