		| Abstract: | 
		In the astronomical Virtual Observatory, provenance metadata provide
 information on the processing history of the data. This is important to
 assert quality and truthfulness of the data, and  potentially be able
 to replay some of the processing steps. The ProvTAP specification is an IVOA Working draft
 defining how to serve provenance metadata via TAP, the Table Acces
 Protocol, which allows to query table and catalog services via the Astronomical Data Query Language (ADQL). ProvTAP services should allow
 finding out all activities, entities, or agents that fulfill certain
 conditions. Several implementations and developments are presented. The CDS
 ProvTAP service describes provenance metadata for the generation of HiPS image datasets. The
 CTA ProvTAP service will provide access to metadata describing the
 processing of CTA event lists. ARI-GAVO prototyped specialized query
 functions that could facilitate accomplishing the goals of ProvTAP users. |
