| 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. |
