Context

Data origin is required for end users to understand data, for citation and for reusability.

We propose to list meta-data required to provide sufficient traceability to end-users in order to improve the understanding of the resultsets and enabling its reuse and its.

Use cases

  • To get provenance information easier (for instance: author, publication dates, provider, ...) example: Query the Gaia catalogue using VO services (for instance with topcat or any other VO-software). The registry lists Data Center (eg: Gavo, VizieR, ESA) which provides Gaia tables using TAP. The results returns VOTable having information in the header. However, the information depends of the implementation.
  • Relevant meta-data for final users to cite resources.
  • Fill the AAS citation template (G.Muench) Example : "we searched optical astrometric data of these sources from the Gaia (Gaia Collaboration et al. 2016) Early Data Release 3 (Gaia Collaboration et al. 2021) via the Gaia archive (Gaia Collaboration 2020)."
  • Relevant meta-data for final users to understand Data Origin.
    Table provided by a Data Center can be a copy of an existing resource. For instance, a table published in a journal or by a Space Agency is also hosted in a Data Center like CDS, GAVO, etc. The data curation depends of the Data Center which can add associated data, enrich meta-data (eg: add filter for magnitude) or make a sub-selection of Columns.
  • Give me a bibliography of everything I’ve used in the workflow (M.Demleitner)

Expected Medata

Metadata that can enrich a VOTable output:

  • Author(s) / Space agency
  • Editor(s), Journal
  • Article ref.
  • Institute
  • Provider, Datacenter, Creator
  • Date(s)
  • DOI, bibcode...
  • Access protocol
  • Licences
  • Curation level
  • Any additional information in text plain that complete the result
