Ah! Thanks. I missed that somehow when the discussion immediately
moved back to DM considerations. It's not quite as concise as the
napkin model, but not too bad. This example undoubtedly doesn't
cover the full range of VOTable flavors that could be returned in
response to different queries. To support this we would likely be
obliged to add full VOTable support.
A productive avenue might be to combine a simple native VOEvent time
series element to cover the proverbial 90% of the cases, and
encourage using <References> to external SSA compliant VOTables for
the more demanding 10%.
A goal with this and the other semantic improvements to VOEvent that
are on the table, e.g., orbital elements, would be to demonstrate
compatibility with GCN (that Scott is already doing and others have
tackled before), and with other such services as SNEWS (ditto Kate),
but also with various types of natural language publications such as
CBAT, MPC and ATEL.
