Open Provenance Model Workshop: Towards Provenance Challenge 3

Aims

We released the first version of the Open Provenance Model (OPM). Teams have commented on the document, have recently published papers related to OPM, or have begun implementation work around OPM. It would be beneficial for the community to share this experience in a focused workshow, with the following goals:

• share feedback on the OPM specification
• share practical experience with OPM
• identify issues to be addressed in second draft of the OPM (or other documents)
• plan an inter-operability activity (provenance challenge 3) based on OPM

This workshop will be held on Thursday June 19th, in Salt Lake City, right after IPAW'2008.

Programme

The workshop is aiming at discussions, and the programme allows plenty of time for these. Please contact l.moreau@ecs.soton.ac.uk if you wish to be contribute to the programme.

• 8.00-8.30: Breakfast

• 8.30-10.15: Session 1: OPM: Overview and Feedback In this session, participants are invited to make a short statement about comments they have on the OPM specification or experience they have gained with OPM. The format of presentation should be very brief, a couple of slides, 5 minutes maximum, to allow for discussions.

• • What are agents in OPM? (Luc Moreau)

Registration

A small registration fee will cover the cost of breakfast/lunch/coffee. Details will follow shortly.

Results

The workshop covered a range of issues with the initial specification of OPM. These issues are documented in the FirstOPMWorkshopMinutes. To further improve the OPM, it was decided that the best course of action was to put the OPM into practice through a Third Provenance Challenge.

Third Provenance Challenge

The broad aim of the next provenance challenge will be to test OPM as a means of interoperability between systems. Specifically, the community is interested in:

• identifying what is missing in the OPM as an interoperability layer,
• what is good about the OPM as interoperability layer
• how well the OPM works in various serializations
• expanding the number and variety of workflows used from the Provenance Challenge 2 in order to stretch the kinds of information that must be represented in the OPM.

In addition to these aims, it was suggested that in conjunction with the challenge the following also be done as non-core tasks:

• Identification of useful ontologies to use for data, people, etc. to be used with OPM
• Highlight the "coolest" tools that make use of the OPM

Schedule

The schedule leading up to the Third Provenance Challenge is as follows (dates are due dates):

1. July 15, 2008 - Version 1.01 of OPM
   • Upload the minutes of the meeting expressing the rationale for changes (Paul)
   • Revise the document according to the "easy" comments from the workshop today (OPM 1.01) (Luc)
   • Wikifying the new OPM document (Paul)
2. July 15, 2008 onwards - Review of OPM 1.01
3. Aug 1, 2008 - Submit workflows for the next challenge
   • Volunteers to contribute workflows.
   • Volunteers include Juliana, Paolo, Yogesh, Sergio, David
   • Create a page for a place to upload proposed workflows
   • Submissions should include a paragraph describing why the workflow is particularly novel
   • Submissions can be linked to from here: ThirdProvenanceChallengeWorkflowProposals
4. Sept 1, 2008 = Review workflows for selection
   • Reviews will be judged by the following criteria
     • expressed in english
     • has figures
     • component parts are available for download / source
     • intermediate data made available for all components in the workflow
     • workflows will be reviewed for novelty and new test cases (e.g. collections, iterations)
5. Sept. 30, 2008 - Finalize selected workflows for provenance challenge
6. Sept. 30, 2008 - Serializations posted
7. Oct. 1, 2008 - Specify the challenge (e.g. queries, tasks, etc.
8. Christmas 2008 - Export of data and opm provenance
9. Spring 2009 (around easter...) - Importing and Queries and Provenance Challenge Meeting
