Thanks, Andy. I'll be there.

Yr "query" and "lang" are equivalent IMO to the protocol draft's
"query" and "query-lang". I prefer "query-lang" because it's more
explicit than "lang", which could mean natural language, programming
language, etc. But I take that they have the same semantics.

It is in the protocol, where it's spelled "graph-id". It's listed in
the HTTP Query Parameters table. The cardinality is wrong and I need
to remove the reference to the query language spec, but it's there.

I don't either. I'll mark "query-lang" as optional.

Hope this helps.
