One Open Question “What constitutes a registered searchable registry for the RofR?” We tell clients to look for: A vg:Registry record with RISearch OR A vg:Registry record with AUX RegTAP capability OR A RegTAP service (somehow associate it back as registered) Oct 2016 IVOA Interoperability Meeting -- Trieste
