I'm not sure we'll need it right away but it'll be good to know its there. > The use of Reification Done Right (RDR) as an extension for arbitrary > statements about properties: > http://wiki.bigdata.com/wiki/index.php/Reification_Done_Right. For those playing along at home this extension to RDF should allow us to fully represent Wikidata in RDF (well, with the extension) and it'd support SPARQL. I'm not really a fan of SPARQL as a language _but_ it has the advantage of, at least in the case of BigData, having a nice optimizer and exposing several extension points. Those extension points would allow us to make a language dependant property just like we did with Gremlin (the label one) and would allow us to rewrite properties like country to perform the appropriate traversals. Theoretically, at least. TASK DETAIL https://phabricator.wikimedia.org/T88717 REPLY HANDLER ACTIONS Reply to comment or attach files, or !close, !claim, !unsubscribe or !assign <username>.
