Not sure it is the correct place to discuss that, but I am working on the installation of Wikibase alongside SemanticMediaWiki in the same Mediawiki instance.
(not sure the 'Semantic' is useful for the rest of that mail, but anyway...)
To allow human-readable links from (Semantic)MediaWiki pages to Wikibase pages, I plan to use the DisplayTitle extension.
I would need Wikibase to have an additional feature when saving the (english?) label of a page: also save it as the 'displaytitle' of that page in the 'page_props' table.
The question is: how can I add this hook in Wikibase saving process?
Any help is welcome.
