I believe that issue-41 does have significant overlap with issue-40. The UC&R now has a UC to cover both <http://www.w3.org/2012/ldp/wiki/Use_Cases_And_Requirements#UC8:_Managing_non-RDF_Resources>. I've used the text of issue-41 as a the beginnings of a scenario - it would be good to put together some RDF for this along the lines of the other UCs.

As per the discussion, there may be two different scenarios here. One with a single asset posted along with the RDF, and another with multiple assets.
Assuming each asset has its own URI, it would be possible to distinguish them by their media type, if this were explicitly added when they were added.

Steve.

Based on that feedback, raising this as a separate user story; if it happens to drive the same technical requirements, fine.
