RDF ingestion is problematic for Wikidata, because importing a dataset to Wikidata requires reconciling existing entities so as to avoid duplicare entries. The easiest way to achieve that is to publish your dataset online, create a linking Wikidata property for it, then ask for it to be imported in https://mix-n-match.toolforge.org where reconciliation can be done by the crowd.

Last I checked mix-n-match was using CSV, while this is okay, it still would be nicer to have direct RDF ingestion. And yes, I realize the reason why Wikidata does not have it, but it is not impossible to provide, just really difficult. I would work on it if I had more time and would likely sometime in the future.
