VOEvent query language (SEAP?)

[Doug Tody]

Elizabeth -

I took a quick look at the SEAP page you reference below.  In addition
to STAP/SIAP, you may also want to look at the new SSAP query protocol.
Although events would seem to have little to do with spectra, most
of the SSAP protocol is actually generic, and it does allow general
queries by spatial/spectral/time ranges, by ID etc., can support solar
or planetary coordinate systems, plus the query response is based on
the Characterization model.  This is probably a better basis for a
SEAP protocol than the older SIAP V1 protocol.
