If you don't want to change the title, that's also fine by me, but please close this matter either way (for me) via a clear Yes/No response. Interpreting  silence is eternally challenging  :-)

The title "RDF Data Spaces and Datasets" rather strongly suggests, I think, that these spaces could also hold _datasets_.   It even seems to be making the point that RDF data is triples *or* quads.

Sandro --

I'm OK with the implicit suggestions you seem not to like, because I think that RDF data *does* include both triples *and* quads, and that RDF Data Spaces *can* hold RDF Datasets (and vice versa!) ... 

"and" is ambiguously commutative.  This title should mean the same with a bit of word shifting -- but none of these permutations I can think of seem to me to communicate quite the same meaning as any of the others --

- "RDF Spaces and Datasets"
- "RDF Spaces and RDF Datasets"
- "RDF Datasets and Spaces"
- "RDF Datasets and Data Spaces"
- "Datasets and RDF Spaces"
- "RDF Data Spaces and Datasets"
- "RDF Data Spaces and RDF Datasets"
- "RDF Datasets and RDF Data Spaces"

I would suggest title rev to "RDF Datasets and RDF Data Spaces".  

I think this breaks (some, most, all?) of the implications you don't like (and breaks more of these than its closest cousin, "RDF Data Spaces and RDF Datasets"), and easily leads into definition of the two terms, and then discussion of how they interact and otherwise operate...

I'm sure one of those (I think g-snap?) was meant to be "== graph state".  I'm fairly sure the other was meant to be something else, but I'm not sure what that would be...

> I think that matches current usage much better than the current "RDF Graph" definition.   If we do this, then the title might be "RDF Graph Spaces and Datasets" or some such. Also, as I get more familiar with the document, I see spaces coming up in less and less of the text, so maybe the title is just "RDF Datasets" or something.   OR maybe there is no document, and all this stuff ends up in other places.    Long discussion.

The need for "[Data] Spaces" or *some* new term comes because "dataset" and "graph" are both overused, overloaded, and confusing (and yes, that effect is still felt on "RDF graph").

"[Data] Spaces" is a new term in this arena -- and thus we get to define it clearly.

I think dropping it because you're familiar with the conversation will just bring us back to where we were before this document... and that's not a win for anyone.
