You may have encountered the COinS-PMH idea in Dan Chudnov’s presentation at Access last week. This blog now contains COinS-PMH links; if you don’t have a COinS-PMH client (i.e. if you’re not Dan Chudnov), view source and search for Z3988 to see them. These links allow a suitable client to retrieve simple Dublin Core records for every posting using the OAI-PMH protocol. You can see one thing they’re good for in a screenshot of the view from Dan’s Firefox extension, and read some more discussion. As clients emerge and develop, this will be a mechanism for providing good metadata to any external service, with no more overhead than is required to run an OAI server (which everybody does, right?). I’ll package this as a Wordpress plugin shortly.
