March 13 Data Usage Vocabulary Status Report

Hi all,

I'm hoping to provide period updates via email on the status of where the
data usage vocabulary is headed.  Attached is a slide show presentation
that provides a list of the requirements taken from the use case document
and proposed use cases that "might" be use to illustrate data usage
principles in the vocabulary document.

We've also drawn up a "conceptual model".  I lacked the tools on the road
to put together a UML diagram so interconnected bubbles will have to
suffice until next week.  A bubble may be a generalization representing
many classes or a single class.

A few observations that I thought was worth noting:

   - The proposed model is a "glue" model intersecting with existing
   vocabularies and new (data quality).
   - I've got a concern about using to many science oriented use cases to
   illustrate points in the document because the desire is to appeal to a
   wider audience.
   - This right now is describing  data usage for Agents (Person,
   Organizations) and is devoid of supporting feedback from machines.
   - I'm not sure if we should show provenance in the model.  I put it in
   as a bubble, but it could certainly be used to track any activities.
   - What should we do with citations?  Many different approaches out
   there.  I feel like we should at least suggest alternatives.

Your questions and comments are most welcome. Please point out anything
that you feel might be missing.

Thanks,

Eric and Bernadette
