It is gratifying to see all of the traffic about extension schemas on this listserve!! And I echo the good words of Bartek Plichta from MSU: the meeting last month at Harvard was a big help to all of us. (Thank you again, Robin Wendler!) Since we plan to start a new round of data capture next week, we have cooked up our seven revised schemas, and will freeze them until June: (1) audio (big debt to Dave Ackerman at Harvard) (2) image (NISO, sort of, but with some added stuff) (3) text (4) video (5) descriptive (for the moment a variant on qualified Dublin Core -- read the explanation) (6) rights (7) digiprov (another big debt to Dave Ackerman). Get to them from this page: http://lcweb.loc.gov/rr/mopic/avprot/metsmenu2.html. You will see references to the Harvard meeting in the text and in some added notes in the linked data dictionary. Comments and corrections much appreciated. Meanwhile, for those interested in our in-development metadata capture database, see the links from the "About Capturing" menu item here: http://lcweb.loc.gov/rr/mopic/avprot/avlcdocs.html#md. Later, when ready, we plan to make more tools and elements available for those who are interested. Best wishes from Carl Fleischhauer and the LC audio-visual team, much aided by our contractor User Technology Associates.
