All but one of those repos no longer exist...

@Addshore is https://github.com/wmde/WikibaseDataModelJavaScript still used? Should it be included in codesearch?

Wikibase-DataModel-JavaScript exists so I'd say that WikibaseDataModelJavaScript should be included in codesearch.

Some other repos might have been renamed, e.g. to https://github.com/wmde/WikibaseDataModelSerialization (?)

All are used AFAIK but some are moved to gerrit.
