I've been using the
<http://wikidata.org/ontology#> namespace for
datatype properties for some time (more than a year).
Now I can see everywhere only the <http://wikiba.se/ontology#> ns.
Was there some reason for change? Are these two somehow compatible? Will
the first one be deprecated?
The items in wikiba.se/ontology hierarchy are those that would be
relevant and would have the same meaning for any Wikibase install - i.e.
individual statements, ranks, properties, etc., basic data type
predicates. They do not depend on particular Wikibase instance, thus
they were moved to wikiba.se. If you have your own Wikibase install,
your items and properties would carry your domain name, since they are
not Wikidata items. But Wikibase ontology would stay the same. Thus the
And yes, the old form of the ontology URLs will not be used anymore on
Wikidata or Wikibase code.
