WP4 Provenance Workshop


Provenance information helps to explore the traceability of products, find contact information and acknowledge people. Providing provenance information allows a user to assess the quality and reliability of the products. If the stored information is sufficiently fine grained, it is possible to enable the reproducibility of an activity or sequence of activities.

Recently the IVOA released a standard to structure provenance metadata and several implementations are in development in order to capture, store, access and visualize the provenance of astronomy data products. This meeting will focus on technical solutions with presentations, demonstrations, hands-on sessions and discussions. The objective is also to collect the requirements of ESFRI projects in order to build the road map of future developments.

The IVOA Provenance data model can be found here:

This workshop was accessible online through the Zoom visioconference system.

        HEK database: solar events using VOEvent

        The SPoCA-suite provide two modules, one for Active Region (AR) detection, and one for Coronal Holes(CH) detection, to the SDO Event Detection System (EDS). It runs in near-real times at Lockheed Martin Solar and Astrophysics Laboratory. Every four hours, the EDS generates and uploads the SPoCA entries into the AR and CH Catalogs of the HEK or Heliophysics Events Knowledgebase.

        The VOEvent standard of 2006 is used in the HEK. In this talk, we analyze the provenance information that is encoded in the field of the VOEvent for the SPoCA-AR and SPoCA-CH event, and discuss how this information could be completed or reorganized in view the proposed provenance data model.

        European VLBI Network (EVN) Archive

        In this use-case presentation the EVN Archive and its provenance challenges will be presented.

        The EVN is a proposal-driven open-access instrument for VLBI astronomy. There is considerable interest -- not least from funding agencies -- about the conversion of the data taken into papers published in the scientific literature (which in our case can be restricted to those registered in the Harvard-hosted register, ADS). JIVE is currently working on schemas to record this information and investigating tooling to harvest it (semi-)automatically.

        Speakers: Des Small (JIVE) , Harro Verkouter (Joint Institute for VLBI ERIC) , Mark Kettenis (JIVE)
