Known issues to work on:
- For very large aggregations, it would be useful to have some way to split between multiple resource maps.
- For very large and regular aggregations, it would also be useful to have some way to include resource without enumerating all of them explicitly. For example via a query or URI pattern.
- dc:extent
dc:extent's object is a SizeOrDuration resource, not a literal. We need a new extent vocabulary entry, or to use a blank node and rdf:value.
