Even tougher question would be what happens if there's a redirect on property. Is this even possible? owl:sameAs may not even accept properties as parameters, at least in some meanings of OWL. And as for support in inference, no idea at all.

daniel mentioned this in T96590: [Task] Include additional entity IDs (redirects) in entities returned from the API..Apr 20 2015, 6:23 PM

See also T96590, which asks for redirect info to be included the the JSON rendering of entities.

Wikibase currently does not allow properties to be redirected or merged, but we have not committed to a guarantee that we will never allow this.

owl:sameAs may not even accept properties as parameters, at least in some meanings of OWL. And as for support in inference, no idea at all.

Wikibase properties are not OWL properties, and should never be used as if they were. So I see no problem there.

As to support for inference... I would have expected triple stores / SPARQL engines to cater to basic needs like this. Seems like we are further away from a functioning semantic web than I thought...

Blazegraph has a step where IRI can be converted to internal representation, and we could plug in there and implement aliasing that way (see also T96490). That probably would work for properties too, but of course it's not portable. I'm ok with the fact that we don't allow it now and we'll cross that bridge when we come to it.

Tobi_WMDE_SW set Security to None.

The cases we're looking for in RDF, assuming Q6 is a redirect to Q4:

If the output is for /wiki/Special:EntityData/Q6.rdf?flavor=dump, there should be Q6 owl:sameAs Q4. Data on Q4 is optional.
If the output is for /wiki/Special:EntityData/Q6.rdf?flavor=somethingelse, there should be Q6 owl:sameAs Q4 present in the data, and the data on Q4.
For dump, there should be data for Q4 and the data for Q6 should be included as Q6 owl:sameAs Q4. No other data about Q6 (i.e. not duplicate of Q4 data) should be present.

NOTE: above patches only include info about redirects that were followed to the data. Including info about ALL redirects is still pending. Perhaps we should split the ticket.
