What cool stuff have we done?

Tomorrow evening [1] I'm presenting about all the cool new stuff in RDF 
1.1.   What should I put on the list?   (I'll also be doing this in June 
at SemTech.)

Here are the things I can think of, that I can say proudly to this 
audience, which I think has lots of SPARQL experience and some OWL 
experience:

- Turtle now meticulously defined, with extensive test suite (will be 
joining RDF/XML and RDFa as "Recommended" syntax for RDF)
- Turtle no longer sometimes needs a space before the period
- JSON-LD allows nice-looking JSON to be read/written as RDF (another 
"Recommended" syntax for RDF)
- standard way to replace blank nodes with IRIs (genid)
- rdf:HTML datatype provides a practical way to put HTML fragments in RDF
- plain literals (w/o lang) and xs:string literals are now the same thing
- sparql's named graph / dataset model is now clarified and part of RDF
- trig provides a syntax for datasets (collections of separable graphs)
- in general, documents are being rewritten to be simpler and clearer - 
for now, see http://www.w3.org/TR/rdf11-concepts/

What am I missing?   What else are you really pleased about or proud 
that we've done?   I only have 20 minutes, so I think the above list, 
with one slide per item, is about the right length.

Also, depending on time and the mood of the audience, I might ask about 
some of our remaining issues (really the At Risk ones).  The two that I 
think I can explain very clearly:

- should turtle have PREFIX & BASE like SPARQL or @prefix & @base like 
n3?  (Currently we're allowing both styles)

- can you use a blank node as the graph label in a dataset, or do you 
have to invent a URL for each graph?  (Currently JSON-LD and some SPARQL 
engines allow them, but the Trig and Concepts spec disallow them)

Input before 2pm Boston Time most welcome.
