Provenance issues

[ptgolden]

In the provenance graph we currently have, there are statements like this one:

"specializationOf": "http://n2t.net/ark:/99152/p086kj9kr9q",
"wasRevisionOf": 
{
    "id": "http://n2t.net/ark:/99152/p086kj9kr9q?version=0"
}

Couple questions:

1. Does wasRevisionOf need to be a JSON object? Can it be a simple string, with the mapping to id done in the JSON-LD context?
2. Should we have wasRevisionOf values for new assertions/collections? wasRevisionOf only makes sense to me when the new version was actually a revision of something that already existed.

Also, we're not currently including type information (i.e. prov:Activity and prov:Entity). Was the on purpose? Are those implied by the relationships between things?
