ObsTAP.creator_name multiplicity

[Guillaume Mella]

Hi,

Sorry for the confusion, there is no aggregating mecanism on data. At 
the present time, we do not process data and only have to register in 
the same database single observation references coming from multiple 
sources.

We encountered this case when we asked for the PI information per record 
and get two people as result.

Final question could be:  how to fill the creator_name for a dataproduct 
associated to a program handled by two persons ?

Cheers,
