[Wikidata-bugs] [Maniphest] [Updated] T89949: RDF mapping should not assert that .../entity/Q123 is-a Wikidata item

Our primary goal is to encode the JSON information in RDF, and possibly to 
enrich this information where it makes sense in an RDF-context (e.g., by adding 
links to other datasets). The JSON data includes the entity type, so it is 
clear that we want to encode it in RDF in some way. As I said, my understanding 
is that Q42 *is* an item for a suitable sense of "item", just as 
https://phabricator.wikimedia.org/P31 is a "property" in this sense. In neither 
case are we referring to the HTML page or any other electronic document. The 
confusion arises from your preconception of the item class referring to a 
document or "description", which in turn is understandable given our lack of 
up-to-date documentation for this vocabulary.

We can just invent new vocabulary as needed for exporting data about the HTML 
item pages, e.g., by introducing an ItemDocument class to refer to the 
documents. I think including data in RDF that we do not even have in our JSON 
exports is secondary for now. In fact, creating RDF exports for data that is 
collected by MediaWiki for every page seems a much bigger task that is hardly 
addressed in a satisfactory way by the snippet pasted above. Something like the 
SIOC vocabulary should probably be used there, and a suitable linked-data 
interface for accessing all revisions would be needed. I am not in favour of 
creating a makeshift solution now that mixes data that is special to Wikibase 
with data that should be there for all MW installations. MW should have it's 
own linked-data export for page metadata, and Wikidata should merely link to 
the relevant URIs from its data exports.
