Hi Mark & Francois,

If there is time I would like to discuss the proposal from Francois to
"extend" ObsCore with Radio-specific information by using a separate
table for these properties and doing an ADQL JOIN operation on an
existing ObsCore column.

There are some challenges for VLBI visibility data with that approach
since the underlying data sets of most VLBI arrays contain multiple
targets which have to be represented as multiple rows in ObsTAP.  My
proposal would be that I give a short (<5min) presentation sketching
the problem and possible solutions and then have a (short) discussion
to fill the remainder of a 10 minute timeslot.

(Already briefly discussed within the ESCAPE context)

Thanks,

Mark
