Hello, I just gave that talk earlier today.  :)

My reason for wanting to query by position, time, and concept is that I'm 
working on a VOTech science case to match VOEvent packets with 
observations from Aladin described by the Characterization schema. I have 
VOEvents and Characterization files stored in a Sesame knowledgebase for 
test queries. I'm testing first against spatial matches and second against 
spatial and temporal matches since those are the two easiest test cases 
for me to visualize.

I would definitely like to explore a simple event access protocol - I 
started to jot some thoughts down last autumn at 
http://wiki.astrogrid.org/bin/view/Astrogrid/SimpleEventAccessProtocol, 
but I'm currently using the AstroGrid STAP service implementation since 1) 
it already does most of what I want for my first test queries (RA, Dec, 
time, plus assorted optional parameters), and 2) Kevin Benson has already 
written the code.

I would like to attend the VOEvent workshop in June - will there be a 
chance to discuss SEAP then?

cheers,
Elizabeth
