Re: PROV-ISSUE-65 (domain-specific-info): How is domain specific data combined with the generic model [Conceptual Model]

I'd like to add:

I think it is important that when domain specific information is added, it 
appears in such a way that applications that do not understand it can safely 
ignore it and still be able to use the underlying generic provenance information.

This shouldn't be hard to achieve, but I think it's an important principle to 
underpin extensibility.

It is not clear in the current document where this domain-specific information goes.

The attribute names might be domain-specific, as I don't think "type", "location", "creator" or "content" are defined in the model, but that might be a mistake in the model. Can attribute types be domain-specific?

I'm not clear whether the list of examples, "coordinate, address..." are examples of attribute types or something else. It is said that "Location is an OPTIONAL characteristics of BOB". I'm not sure if "characteristic" is related to "attribute", and if this is implying a generic attribute type called "location".
