Provenance in Astronomy: data model and implementations

Aug 28, 2018, 12:00 PM → Aug 30, 2018, 2:00 PM Europe/Paris

Salle du Conseil (Observatoire de Paris)

The objective of this meeting is to finalize the IVOA Provenance Data Model working draft before entering the promotion process to make it an IVOA recommendation. A session of the meeting will be dedicated to the presentation of the different implementations (and use cases) based on this standard.

Tuesday, August 28

2:00 PM → 6:00 PM IVOA data model open discussions

2:00 PM Core data model and diagrams

2:20 PM Definition of specialized entitities

Our Astronomy use cases generally require some information on the activities : description, configuration (config file, parameters) and context (ambient conditions, execution environment, ...)

document IVOA_Entities.pdf

2:40 PM New relations to specialized entities

Activity description, configuration and context would require specialized relations : hadDescription, hadConfiguration, hadContext

3:00 PM Mapping with PROV

Following the requirements, we should be able to serialize our model in the W3C PROV formats, e.g. by defining specific values for prov:type for the different entities and relations

3:20 PM Mapping with ProvONE for workflows

Some concepts relevant for astronomy may already exist in the ProvONE extension to PROV, we should ensure that our concepts are compatible. We also have the example of UniProv that uses partially PROV, ProvONE and internal concepts

3:40 PM ActivityFlow status?

4:00 PM Coffee break

4:20 PM ProvSAP

4:40 PM ProvTAP

5:00 PM Preparation of ADASS in College Park

François will have a talk on ProvTAP, we should propose posters on ProvDM and ProvSAP as well to advertize more widely the IVOA Provenance data model
