Jeepers, no posts for 3+ months and then two in one day! The truth is that I hadn’t realized the last post was still sitting in my drafts folder more than a month after I wrote it.
Moving on…
A number of folks have been interested in installing the Registry, especially since we’ve talked before about […]

If you’ve been watching the Registry closely (and we know you have), you’ll have noticed that a few weeks ago we started supporting the registration of metadata schemas. It’s not finished and far from perfect, but the perfect can often be the enemy of the good and at the moment it’s, well, good enough for […]

You can now retrieve a snapshot in time of the RDF or XSD serialization of a Concept/Scheme/Vocabulary by appending a ‘TimeSlice’ to the URI. For example:
http://metadataregistry.org/uri/NSDLEdLvl/ts/20060422200002.rdforhttp://metadataregistry.org/uri/NSDLEdLvl/ts/20060422200002.xsd
will always and forever retrieve the SKOS/RDF or XML Schema representation of the NSDL Ed Level Vocabulary as it appeared at 2 seconds after 8PM on April 22, 2006 (2006-04-22 […]

We’ve been promising for a while now that we’d make it easier, actually a better word is ‘possible’, for Vocabulary Owners to add ‘Members’ to Owner/Agents and ‘Maintainers’ to Vocabularies. We finally implemented it today! It’s unfortunate that it has taken us so long, since one of the primary goals of the Registry is to […]

We’ve updated the front page of the Registry to include a Registry-specific news feed from the Registry blog. You can subscribe to it right from (t)here and stay up-to-date with the Registry as we move it forward. Notes like this will be typical and probably pretty frequent over the next few months.

If you tried to access some of the links on this blog and discovered they were broken, they’re fixed now (dropped a .htaccess file on the floor).

Since the beginning of the Metadata Registry project, we’ve been running our own web server. After a significant number of service outages this year, we finally decided that had to change…

If you tried to request your password and nothing happened, it’s because mail was broken on the server. Actually I had closed the port in the firewall a very long time ago and since a password request is the only thing that normally uses mail on the Registry, I hadn’t noticed.
Today I needed to register […]

What does cooking have to do with registries? Quite a lot, as it turns out. In this first guest appearance, Tom Baker describes the “cookbook” drafted by Alistair Miles that enables Apache HTTP servers to provide different responses for serving RDFS/OWL vocabularies, depending on the nature of the requestor.

There was a discussion about the possibility of creating copies of the dc namespace elements in the dcterms namespace. Despite my personal strong support, Andy decided that there wasn’t a strong consensus for or against and that it might be best to table the suggestion until some of the other architecture ‘earthquakes’ subsided.
