This does have the side-effect that annnotations of version n are not naturally retrieved with version n+1. That's true, of course, for all annotated resources that are versioned if the version identifier is part of the URI. > 2.

This is solvable potentially by > increasing the cardinality for 'context'. We did talk about this use case quite extensively and did plan to permit multiple context triples exactly as you suggest. -Ralph
