We talked about something like this at the Open Library meeting last Friday. The ol list is [log in to unmask] (join at http://mail.archive.org/cgi-bin/mailman/listinfo/ol-lib). I think of this as a (or one or more) translate service between IDs. It's a realization that we will never have a unique ID that everyone agrees on, that most bibliographic items are really more than one thing, but that since we have data about the bibliographic item we have many opportunities to make connections even though people have used different identifiers. So we could use an "ID-switcher" to move among data stores and services. Is that the kind of thing you are thinking of? kc > > Tim Shearer wrote: >> Howdy folks, >> >> I've been playing and thinking.
