Dear METS members, Maybe my question is naive but keeping track of all the work done in metadata area is difficult. I can't understand the relation between the Core metadata element set effort and METS. It seems to me that there are some ovarlapping areas. And of course there are evident ovarlapping areas between Core element set and NISO/MIX. It looks like the fomer was a first step toward the latter, but maybe I' wrong. Thanks in advance for any advice and explanation. Fabio Ciotti
