Hello all,
Thanks to Lucas who filled the necessary requirements, Wikidata now appears in the LOD cloud graph: http://lod-cloud.net
Currently, the graph doesn't display all the actual connections of Wikidata. The only connections that show up are the properties that link to other projects or databases, and having a specific statement on them to link to an RDF endpoint.
If you see something missing, you can contribute by adding the statement “formatter URI for RDF resource” on properties where the resource supports RDF (example https://www.wikidata.org/wiki/Property:P214#P1921).
You can learn more about the procedure to update the graph and a list of the existing and missing datasets here https://www.wikidata.org/wiki/User:Lucas_Werkmeister_(WMDE)/LOD_Cloud,
Thanks to Lucas and John for making this happening!
