Proposed change of name for ProvDAL --> ProvSAP (François Bonnarel):

During the TCG meeting, it has been objected that the name ProvDAL was confusing. Just because in DAL WG, everything is .... DAL !!! I (FB must confess that I think that I was the one who introduced the name ProvDAL, by proximity with "SimDAL". Just because SimDAL is strongly bound to a model and has a PARAMETER based interface. But actually this name (SimDAL) is very atypical in the VO and not really appropriate.

On the other side, everything which has a parameter-based interface, is called Simple Access Protocol in the VO (SSAP, SIAP 1 or 2, SLAP, SCS,...) thus marking an opposition with using ADQL based interface which offers much more query complexity. So after thinking to it and eliminating other bad options we made a consensus on ProvSAP for "Provenance simple access protocol"). I hope that everybody in the group is happy with that. ProvSAP and ProvTAP are easily distinguished this way.

Proposed restructuration of the ProvDM draft:

  • section on the core model (without Descriptions, Parameters, ActivityFlow), so fully W3C compliant,
  • section for the Descriptions, that are only linked through the Activity-ActivityDescription relation (this would go well with the serialization as a Bundle in the W3C context, that influences the Activity instance)
  • section for Parameter (connection of Configuration with Provenance), for which the main use case would be the compatibility with web services in the VO framework, i.e. a Parameter class directly linked to the Activity Class, seen as a simplified Entity that influences the Activity instance. If it is Used, it should then be seen as a general Entity.
  • the relation Entity-EntityDescription relation will not be part of the first standard, paragraph in the Appendices (it could be a way to connect Data Structuration with Provenance)
  • section on ActivityFlow (connection of Workflows with Provenance), but moved to the Appendices and out of the standard for now (still not well understood)
