> Jerry McDonough has completed a new version of the METS schema. > The new > version is is available at: > http://www.loc.gov/standards/mets/mets.xsd > and is ready for review. Please submit comments to the METS listserv. > The new schema has comments on specific changes in the comments at the top. The major change is the addition of a new section for METS object behaviors, courtesy of Sandy Payette at Cornell and the Fedora gang. This seems a good time to report on some issues that came up at the Pittsburgh meeting. One question which arose was whether the use of ##any element declarations on the mdWrap element could be modified to allow for more than one root element beneath mdWrap. It turns out that this is possible. However, doing so means that the various root elements can come from different namespaces/extension schema. My personal feeling is that this is, if not bad, at least not elegant. I would rather have the elements within any given mdWrap all come from a single extension schema. However, I can see benefits for greater flexibility here as well. I think we should try to discuss this on the list; if the consensus is that opening up mdWrap for multiple schema subelements is a good idea, I'll make that change. Another issue that arose was whether it was possible to alter the METS schema to allow for attributes from other namespaces within METS elements. While this is possible, it turns out that the changes necessary to enable foreign namespace attributes on METS elements compromise validation software's ability to ensure ID/IDREF matching on any element where attributes from other namespaces are allowed. While there are potential work arounds, they are rather ugly. For the moment, I have decided to forego enabling foreign namespace attributes in METS. Hope everyone has a happy holidays!
