Provenance Working Draft

[Kristin Riebe]

Dear Data Modelers,

the working draft for the Provenance Data Model is now available at
http://www.ivoa.net/documents/ProvenanceDM/

We are still about to implement the model and test serialisations in our
different use cases. You are very welcome to try it for your own use
cases and give us some feedback!

There are some remaining issues which we will discuss in our Provenance
meetings; the next one is scheduled for 13th December 2016 in
Strasbourg, see
http://wiki.ivoa.net/twiki/bin/view/IVOA/ObservationProvenanceDataModel
(where you can also find upcoming events in the future and a link to the
volute repository)
and
http://wiki.ivoa.net/twiki/bin/view/IVOA/ProvDayDec2016

Please put your name there if you want to participate as well!

Here are some of the main discussion points which need to be addressed
in the future:

* Description classes
- Which projects need them, which don't

* "ActivityFlow"
- Class for grouping activities or whole parts of a provenance graph
  (of a workflow) together
- When introducing this class we needed to allow multiple
wasGeneratedBy-activities for one entity, though logically there should
be only one "true" activity that generated an entity; but if activities
can be grouped, then it must be allowed to have wasGeneratedBy-links to
the activity-groups (ActivityFlow) as well

* VO-DML representation
- We are working on this. It seems that we have included many double
compositions (at the relation-classes in between), which seem not to be
allowed by VO-DML. We have to carefully check this.

* Links to other data models
- We have identified links with the Dataset Metadata Model, but we need
to further investigate the other data models (e.g. SimDM)

You are very welcome to join us and help/give advice on one or more of
the points above!

Cheers,

Kristin Riebe, Mathieu Servillat and the Provenance Working Group
