ProvDM:

• Parameter as an Entity, or as an independent class?
  • Parameter class
    • specific concept in IVOA (and in general)
    • link to configuration of an Activity (though it is not in the main requirement for IVOA Provenance)
    • no history needed in this context
    • exist in SimDB
    • However
      • What if we want the history of a parameter?
      • Some Parameters may in fact be listed as Entities
        • so one need to collect both Parameters and Entities to have a list of input parameters
  • ParameterEntity class
    • logical place in the W3C system
    • specializationOf an Entity with PARAM attributes
    • However
      • Inherits complex relations and attributes
      • Not directly linked to the Activity
        • so what is the difference with a basic Entity?
  • + UWS system use of parameters as a use case
    • All inputs to a UWS job are uws:param objects
    • Need to map Parameters and Input Entities to uws:param
    • The list of inputs with their nature must be given (e.g. as an ActivityDescription + roles for input)
    • Parameters and Entities are very similar, but:
      • A parameter can be written more simply (e.g. PARAM in VOTable, uws:param, POST/GET parameters)
      • An Entity is more complex, one need to store the relation and role in addition to the parameter attributes
  • => The concept of Parameter exist and should appear in the Provenance DM
    • propose two solutions for a use case to discuss the best representation
    • in any case, in the W3C context, Parameters are Entities
• Descriptions: stored as Bundles? link with specializationOf?
  • Seems to be logical
  • Is it an abuse of what is a Bundle ?
  • Note that Bundle is an extension of the W3C core concepts
  • The proposed ActivityDescription serialization as an extended DataLink service descriptor corresponds to this Bundle
• W3C serialization (do we really need an IVOA format?)
  • Mathieu : write a section to describe the serialization of the DM with W3C concepts
  • Parameter as W3C Entity
  • Descriptions as W3C Bundle
  • use specializationOf relation
• ActivityFlow: still issues with the wasGeneratedBy multiplicity (add level attribute?)
  • not in the core model
  • as an extension, different scopes, additional section ?
  • Mireille : Summarize and see how to integrate this to the draft

• status of ProvDAL
• status of ProvTAP
  • new draft
  • example included

• IVOA Victoria : Mireille, François, Ole, Michèle, Mathieu
  • http://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpMay2018MeetingtPage
  • DM: release a new version (good in the context of ASTERICS)
    • with W3C representation
    • with open questions on Parameter
    • discussion in the DM group
  • DAL:
    • discuss the Access documents with the DAL group
• Provenance Week participation (though deadline for posters was in April it seems...)
  • http://provenanceweek2018.org/
  • TaPP Track seems better suited for discussions on Astronomy needs
  • Anastasia may have a poster there
• ASTERICS EDP Forum meeting in Heidelberg, end of June
  • http://www.g-vo.org/edp-forum-2018/
  • plan a provenance discussion there ?
