Discussion

• Last-step flat provenance in more details
  • requirements
  • mandatory fields?
  • FITS keywords?
  • map with other standards (OGIP?)
• Discuss logprov Python package
  • demo
  • doc topics
  • associated coding guidelines
• voprov improvement 
  • should simplify the declaration of descriptions and configuration
  • example of internal OPUS code to autogenerate the prov graph
  • doc and debugging
• Provenance and workflows
  • connector to workflow in last-step provenance
  • mapping CWL to Provenance descriptions
  • workflow attributes: ref to file, and format 
• Storage
  • what is a "provenance record"
  • specifications for a DB ingestion system: from a file, ingest in a relational database structured with the IVOA ProvDM
  • test of NoSQL solution / graph databases
• Query provenance
  • ProvTAP views: should answer use cases
  • query an element of a graph?

Road-map

• logprov
  • create tutorial to build an interface that executes any code (outside Python) with prov tracking
  • documentation
  • dev:
    • use voprov instead of prov
    • to be tested with last version of gammapy
• voprov
  • publish notebook on voprov github
    • use generic filenames
    • add location
    • add EntityDescription.content_type
  • documentation
  • link in doc to the OPUS function that auto generates a graph
  • bugs:
    • update dependency to prov==2.0
  • dev:
    • shortcuts to declare parameter and descriptions
    • shortcut to prov:label
    • YAML output
      • to be defined (IVOA Note?)
    • JSON schema?
    • serializations proposed in voprov
• Last-step flat provenance
  • Prepare an IVOA Note
  • based on ids
  • important to include used and generated ids
  • How to resolve those ids?
    • ProvURL: link to a ProvSAP that can resolve the ids
      • PROVURL keyword in FITS
      • ServiceDescriptor in VOTable?
• ProvTAP
  • Draft before Christmas
  • Discussion in January on IVOA draft
  • Discussion with Gilles on ProvTAP usage
• Provenance and workflows
  • test CWL on a use case, check mapping with prov
    • HESS DR1
    • CTA data challenge
  • internship?
• Domain specific discussions
  • to take place in January-February within ESCAPE
  • SKA (with SKAO, Jesus and IAA, Lourdes, Julian, etc.) 
  • Solar data (with ROB)
  • CTA
