Welcome to The Registry Sandbox!
This is the playground sandbox for the National Science Digital Library Metadata Registry
The Registry Sandbox uses it's own database and login, so you can make a fine mess (please try not to kick the sand out of the sandbox).
If you want to really register a vocabulary, head on over to the Production Metadata Registry
How to begin
The best place to get started might be to see what other folks are doing. Click on 'Browse Vocabularies' over there on the right.
When you're ready to play yourself, here are some Step-by-step illustrated instructions...
If you want to know more about what's going on here, you can see all of the relevant documentation over at the Production Metadata Registry
Complaint (and kudos) department
If you encounter a bug, or would like to make a suggestion, please create a ticket.
Or you can always send us an email...

Part of our server move was prompted by the ever-increasing indexing of our many, many activity feeds. In addition to the overall history feed on the front page, each vocabulary has a history feed: Metadata Registry Change History for Element Set: ‘MARC 21 Elements 00X’ Each element or concept also has its own history feed: … Continue reading Activity feeds fixed →

One of the side effects of our server move was the need to reconfigure our locally-hosted transactional email services, which were always a little flaky — if you have tried to reset your password lately you will no doubt have noticed that the promised email never arrived. That’s fixed now. We switched from self-hosted to … Continue reading Password reset fixed →

…from Rackspace to Digital Ocean and from one large-ish server to several smaller ones, from a relatively prehistoric version of RedHat to the latest Ubuntu 14LTS, from Zend Server+Apache to nginx (openresty actually), and from PHP5.2 to PHP5.5. It really wasn’t as painful as it sounds like it should have been. As part of the move, … Continue reading Server move in progress →

Normally the Registry just hums along quietly and doesn’t demand too much attention. But the last system update we performed seems to have altered our memory usage pretty dramatically and we’re quite suddenly having out-of-memory issues and some heavy swapping. We’ve expanded the server capacity twice already as a stopgap while we investigate, but before … Continue reading Server issues →

When we first designed the NSDL Registry, part of the requirements was that it be able to run in Lynx (seriously) and be usable without JavaScript in all browsers including all versions of IE. As you will probably have noticed, the world of web development has changed a bit in the last 8 years. Lately … Continue reading Still here, folks →

Until lately we’ve been pretty happy with our ISP, Dreamhost. But a few months ago, after several during-the-presentation meltdowns of the Registry we determined that we needed to move to a higher-performing, more reliable server. We could have done the easy thing and moved to a Virtual Private Server at Dreamhost. Instead, we setup an … Continue reading Whoops →

We’re using Benjamin Nowack‘s excellent ARC libraries for a tiny bit of our RDF management. It may surprise you to know that we don’t use a triple store as our primary data store, but we do too many things with the data that we think are cumbersome at best when managed exclusively in a triple store (a subject … Continue reading SPARQL queries →

As of today, the link to Step-by-Step instruction on the Registry front page has been updated (and not a moment too soon). The new link still goes to the Registry Wiki, but the link itself is different, so those of you eager users who have bookmarked the old instructions might want to take a look … Continue reading Check Your Bookmarks! →

As of this week, the familiar NSDL Regisry has a new name–the Open Metadata Registry–and a new logo. The name change reflects the fact that we’re no longer receiving funding from the National Science Foundation on behalf of the National Science Digital Library (NSDL), but also recognizes that the Registry has become one of the … Continue reading Announcing the New Open Metadata Registry →

Over the years we’ve been engaged in a number of discussions in which the ‘readability’ of URIs was raised, either as an issue with non-readable URIs or as a requirement in new URI schemes. At the Registry, we understand and are sensitive to the desire for human readability in URIs. However embedding a language-specific label … Continue reading Readable URIs →
