Hi Everyone,
Here are some comments on the TAP 1.1 proposal.
1) The text proposes
INTERSECTS and CONTAINS are required. POINT, CIRCLE, and POLYGON
are required. POINT (and point-valued columns) cannot be used as
an argument to INTERSECTS.
What is the rationale for not allowing POINT's in INTERSECTS?
2) The text says
A query with MAXREC=0 can be used with a simple query
(e.g. SELECT * FROM some_table) to extract and examine the
VOTable metadata (assuming FORMAT=votable). Note: in this version
of TAP, this is the only mechanism to learn some of the detailed
metadata, such as coordinate systems used.
I thought that TAP_SCHEMA.columns has all of that metadata?
3) I would really like to add a requirement that TAP/async jobs run
immediately if the parameter PHASE=RUN is passed during the initial
submission. As I understand it, this was always intended to be
true, but was never specified. I can work on the text if needed.
Cheers,
Walter Landry
