DATACP interest group proposes to improve the traceability of data
queried through the Virtual Observatory by highlighting the origin
of
the Data.</p>
<p style="line-height: 100%; margin-bottom: 0in" lang="en-US"><br>
</p>
<p style="line-height: 100%; margin-bottom: 0in" lang="en-US">A
short
list of basics metadata that allows to trace the data origin has
been
published in an IVOA note
(<a class="moz-txt-link-freetext" href="https://www.ivoa.net/documents/DataOrigin/">https://www.ivoa.net/documents/DataOrigin/</a>). The document also
proposes a VOTable
serialization, based on existing standards that can be already
used
by softwares like Topcat or Aladin.</p>
<p style="line-height: 100%; margin-bottom: 0in" lang="en-US">The
information include reproducibility such as URL, protocol or
execution date and metadata describing the dataset such as authors
name, sustainable identifier, etc.</p>
<p style="line-height: 100%; margin-bottom: 0in" lang="en-US">We
expect with these metadata to improve the FAIR-VO framework and we
encourage VO implementer to extract and to build the information.

to any VO implementer !</p>
