Right now Commons are able to produce RDF, but prefixes are all wrong:
wdata:M40538870 a schema:Dataset ; schema:about wd:M40538870 ; ... wd:M40538870 p-d:P180 wds:M40538870-D3B1F1D8-C2E4-4C7B-B562-721D6C94CF25 . wds:M40538870-D3B1F1D8-C2E4-4C7B-B562-721D6C94CF25 a wikibase:Statement ; wikibase:rank wikibase:NormalRank ; ps-d:P180 wd-d:Q818891 .
Instead, it should be:
sdcdata:M40538870 a schema:Dataset ; schema:about sdc:M40538870 ; ... sdc:M40538870 p:P180 sdcs:M40538870-D3B1F1D8-C2E4-4C7B-B562-721D6C94CF25 . sdcs:M40538870-D3B1F1D8-C2E4-4C7B-B562-721D6C94CF25 a wikibase:Statement ; wikibase:rank wikibase:NormalRank ; ps:P180 wd:Q818891 .
Note that underlying URIs are good, just the prefix names are wrong. We need to set up configs so that they are correct.
