Aside from simple entailment, I'd expect all the entailment URIs to be capitalized simply because they are acronyms.

OK. I'm updating this along with the capitalization issue. Does anyone have a preference on the tense of feature URIs ("dereference" versus "dereferences")?

I'll consider these for the new IRIs:

sd:DereferencesURIs
sd:UnionDefaultGraph

OK. I'll put that on my todo list, but may not get it in for this draft.


Also, I wanted to mention that I'm going to try to flesh out the modeling of the sd:availableGraphDescriptions property as it's currently rather under-specified.
