"Title proper" is like "main entry" -- it tells you the role the title is playing in the record, not what the title actually is. We could have: - title page title - cover title - title from jewel case insert etc., if that information is important to capture, rather than calling one of them the "title proper" and essentially losing key information about the source of the title. In a situation where you want to display just one title you would have an algorithm in your display code that selects the one to display from a list: first title page, then cover, then supplied.... If you look at AACR/2 it's easy to see that the cataloger is selecting data elements to fit into certain display roles, and in that process losing the meaning of the data elements themselves. This is one of the difficulties in then transforming the current data into something that is based on the meaning of the data rather than its position in the record. Essentially the rule would be: "say what it is, not where you want it to display" And of course, notes about data elements are virtually useless in a data environment. The data elements themselves need to carry that information. As for the dates or versions on a data element, and the entity that created the data, that is being considered by the W3C provenance working group. http://www.w3.org/2011/prov/wiki/Main_Page It might be interesting to offer some use cases from library cataloging as test cases for their work. kc -- Karen Coyle [log in to unmask] http://kcoyle.net ph: 1-510-540-7596 m: 1-510-435-8234 skype: kcoylenet
