OK, thanks to mortenf, I have one each of select, construct, and ask.
I think these are suitable for pasting into proto-wd after
- fixing the \t artifact from TCPWatch
- prolly get rid of the <!-- executing query... -->
comments from the server
- changing the domain to something.example
- getting rid of query-lang=sparql&
- getting rid of &format=xml
- changing &data= to &default-graph-uri=
I'm not sure the construct answer is right; I don't
think the bnode ids line up right. Maybe those details
can be elided.
I haven't found/made an implementation that has named-graph-uri
or a work-alike, so I don't have a trace for that yet.
Eric is building one with a built-in dataset, but he went
to sleep before we could work the kinks out of it.
Here are the params used by the client and the full
trace for select, construct, and ask...
