We are wondering whether it is possible to configure Wikibase and/or JsonConfig for using the local wiki as a source of the values for Wikibase properties with type 'tabular data'. Our current configuration is
$wgJsonConfigModels['JsonConfig.TabularContent.local'] = 'JsonConfig\JCTabularContent';
$wgJsonConfigs['JsonConfig.TabularContent.local'] = array(
'namespace' => 486,
'nsName' => 'Data',
// pattern for page name
'pattern' => '/^[A-Z]*[a-z]*\.tab$/',
'isLocal' => true,
);
but this does not work as desired. Wikibase still searches for *.tab pages in commons.mediawiki.org rather than in the local wiki.
