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...

Activity feeds fixed

Posted by: Jon at 20:54 on Friday, September 19, 2014 GMT
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

Password reset fixed

Posted by: Jon at 21:50 on Thursday, September 18, 2014 GMT
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

Server move in progress

Posted by: Jon at 21:02 on Friday, August 15, 2014 GMT
…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

Server issues

Posted by: Jon at 17:52 on Wednesday, July 23, 2014 GMT
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

Still here, folks

Posted by: Jon at 20:36 on Saturday, February 16, 2013 GMT
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

Whoops

Posted by: Jon at 23:32 on Wednesday, September 28, 2011 GMT
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

SPARQL queries

Posted by: Jon at 14:55 on Thursday, April 14, 2011 GMT
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

Check Your Bookmarks!

Posted by: Diane Hillmann at 19:20 on Tuesday, October 05, 2010 GMT
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!

Announcing the New Open Metadata Registry

Posted by: Diane Hillmann at 21:52 on Tuesday, July 20, 2010 GMT
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

Readable URIs

Posted by: Jon at 12:52 on Thursday, April 08, 2010 GMT
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
