Should triple terms be allowed in subject and object position of triples and triple terms or only in object position.

The issue in question is if triple terms should be only allowed in object position or also in subject position. The Abstract Grammar as defined in the "liberal baseline" allows them in both positions. However, it is an open discussion if allowing them in subject position is harmful in practice. This discussion has so far mainly taken place in the Semantics TF, but it is of general concern, as its outcome determines if a whole class of use cases can be tackled with triple terms, or not.

The discussion is spread over several Github issues, but the most recent thread is triple terms in subject position - issues with RDF/XML?. For a tl;dr just scroll down to the last two comments to get Niklas' and my position.

Please excuse that so far this is a rather sparse description of the issue. I hope to update it with a more thorough treatment and more links after today's Semantics TF meeting.

This discussion depends on the WG's decision to adopt the "liberal baseline" semantics as suggested by the Semantics TF.
