Hi Pete, You are correct. The new schemas need to be reloaded. It's on my list of things to do, but will likely be sometime in January before I can look at it. Cheers! h -----Original Message----- From: DCMI Registry Community [mailto:[log in to unmask]] On Behalf Of Pete Johnston Sent: Thursday, December 21, 2006 5:09 AM To: [log in to unmask] Subject: DCMES data in DCMI Registry I'm not sure whether to send this here or to the DCMI Web site admin folk, but as it raises some broader issues, I think it's probably worth sending it here. This week the content of the "namespace document" describing the terms of the DCMES was updated to reflect changes made by the Usage Board. See news item http://dublincore.org/news/documents.shtml#dcmi20061218terms However, I notice that the views of the descriptions of the DCMES terms provided by the DCMI Registry are still based on the old data e.g. http://dublincore.org/dcregistry/detailServlet?reqType=detail&item=http% 3A%2F%2Fpurl.org%2Fdc%2Felements%2F1.1%2Fsubject > Definition: The topic of the content of the resource. cf. http://purl.org/dc/elements/1.1/subject i.e. the DCMI registry database has the old RDF data stored. I guess someone needs to "crank the handle" which gets it to reload the data from the "namespace document", which is the authoritative source. I guess the same is probably true of various other "metadata registries" out there. And I guess some thought needs to be given as to how that mechanism works in a distributed environment i.e. the DCMI registry is only reading data provided by DCMI, but other such applications may be reading data sources from around the Web, owned by many different agencies. Is it the data source owner's responsibility to ping a registry to say the data source has changed and the registry should reload/reindex? What if the data source owner doesn't even know that some registry has loaded their data? (Could data source owners provide RSS/Atom feeds to do this?) Or does a registry periodically re-GET all its current data sources to check for changes from the version that was stored? Are there other implications of doing that? I seem to recall Harry did some work on mechanisms whereby multiple instances of the DCMI Registry could exchange data, though I'm afraid I can't recall the details. But in any case, that only addresses dissemination between those systems, not how data gets into those systems in the first place.
