Meeting Summary 17 December 2007

The meeting began with a discussion of the new Open Archives Initiative's Object Reuse Exchange specification. Like POWDER, this seeks to create aggregations of resources. However, the similarity is not as great as it seems at first: resources are included in the aggregation through explicit enumeration; and ORE does not provide a way to apply metadata to members of the aggregation. It allows you to create an aggregation and declare who you are, when (and presumably why) you made the aggregation etc. but it doesn't allow you to say 'all the resources in the set are blue.' The POWDER WG will send a formal response to the OAI in the near future. The group discussed recent and very welcome input from members of the Semantic Web community and the imminent meeting with Jeremy Carroll, Dan Brickley and Stuart Williams. The expert opinion has swung from the model published originally to one based on OWL and reification and in recent posts by Jeremy back to the original. The WG is generally of the opinion that what matters is meeting the use cases and that is more important than developing the Semantic Web. We need to be able to freeze the basic data structure as soon as practical and move on. Work has begun on the Primer which will seek to answer 5 questions:
  1. What is it (and why is it better than what I have already)?
  2. What can I do with it (as a producer or consumer of POWDER)?
  3. What do I need for it?
  4. How do I use it?
  5. Is there something I need to worry about?
The group agreed that these were the questions it felt should be answered! Finally, the group briefly discussed plans for an event similar to that held in July. This will be held in London, probably on 18th march 2008 with a strong mobile-element. And with that, the group's work for 2007 was over. Next meeting 7 January.
