Welcome to The Registry!
This is the home page for the National Science Digital Library Metadata Registry.
The Metadata Registry provides services to developers and consumers of controlled vocabularies and is one of the first production deployments of the RDF-based Semantic Web Community's Simple Knowledge Organization System (SKOS)
How to begin
Step-by-step illustrated instructions...
If you just want to experiment and play around a bit, go on over to the Metadata Registry Sandbox. The code is exactly the same, but it's using a non-production database. (Please be careful not to kick any sand out of the box)
NOTE: The sandbox has its own domain now. If you had bookmarked the beta site thinking that it was the sandbox (and we did say that), it will shortly be a real beta site again complete with broken code, wacky ideas, and disappearing data.
Please change your sandbox bookmarks to point to the Metadata Registry Sandbox. Any of the sandcastles that you had built in the beta, back when you thought it was the sandbox, are still there.

We’ve been thinking for some time about how to implement multi-lingual (and multi-script) vocabularies in the Registry. Some Registry users have been experimenting with language and script capability for some time (see Daniel Lovins’ Sandbox Hebrew GMD’s). But it was really when we started working with the RDA vocabularies that we got serious about [ ... ]

Those of you who have actually discovered the Registry and tried to add stuff to it have (I hope) already realized that we had Step-by-step Instructions for doing so. They were old, and we’d added new things (mostly Jon added new things—I just rant, nag and test), so I finally re-did the instructions. [ ... ]

It’s been a busy summer, but not on the Registry front.
We’re currently working on integrating the ARC library so we can handle RDF a bit more intelligently. This will give us import capability, a SPARQL endpoint, and the ability to express vocabularies in more RDF serializations. We’ve also made some improvements to our URI-building [ ... ]

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 [ ... ]

I was talking with Diane this morning about building the schema portion of the Registry and I feel the need to write down some of what we discussed.
For purposes of discussion, we have a draft schema property interface that defines some basic metadata schema property properties. We started the conversation because I was trying [ ... ]

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.rdf or http://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 [ ... ]

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.

The registry database was updated last week, in both the sandbox and the registry, to support history tracking. This is in preparation for finally enabling timeslice retrieval and versioning.We also made some significant changes to the site layout and css, so if things still look a little funky, try refreshing your browser — most browsers [ ... ]
