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 →

On Wed Mar 23 2016 at 20:27:12 UTC, Daniel Lovins, working on the Concept: Value Vocabulary, added the definition (en) Property: Vocabularies used to express concepts or values in instance data. DCMI uses the term Vocabulary Encoding Scheme for these vocabularies, which assumes more internal structure than a term list in text.
On Wed Mar 23 2016 at 20:25:22 UTC, Daniel Lovins, working on the Concept: Data Types, added the definition (en) Property: Syntax Encoding Schemes (SES) are the rules that specify how a value has to be structured. Dublin Core defined Syntax Encoding Schemes as DCMI Metadata Terms - e.g. dcterms:W3CDTF for date specification. The relationship between Dublin Core datatypes and properties is as follows:
Certain properties - e.g. date, identifier, etc. - may be typed by a Syntax Encoding Scheme, where the Syntax Encoding Scheme dictates the syntax of the values used with that property.

On Wed Mar 23 2016 at 20:24:04 UTC, Daniel Lovins, working on the Concept: Controlled Vocabulary, added the definition (en) Property: Prescribed list of terms, headings or codes, each representing a concept.
NOTE: Controlled vocabularies are designed for applications in which it is useful to identify each concept with one consistent label, for example when classifying documents,
indexing them and/or searching them. Thesauri, subject heading schemes and name authority lists are examples of controlled vocabularies.
Definition from ISO 25964
Information and documentation — Thesauri and interoperability with other vocabularies
Part 2: Interoperability with other vocabularies
First Edition, 2013-03-15
On Wed Mar 23 2016 at 20:22:55 UTC, Daniel Lovins, working on the Concept: Controlled Vocabulary, added the definition (en) Property: A list of terms that have been enumerated explicitly. This list is controlled by and is available from a controlled vocabulary registration authority. All terms in a controlled vocabulary must have an unambiguous, non-redundant definition.
NOTE: This is a design goal that may not be true in practice; it depends on how strict the controlled vocabulary registration authority is regarding registration of terms into a controlled vocabulary.
At a minimum, the following two rules must be enforced:
1. If the same term is commonly used to mean different concepts, then its name is explicitly qualified to resolve this ambiguity. NOTE: This rule does not apply to synonym rings.
2. If multiple terms are used to mean the same thing, one of the terms is identified as the preferred term in the controlled vocabulary and the other terms are listed as synonyms or aliases.
(From ANSI/NISO Z39.19-2015)
On Wed Mar 23 2016 at 20:21:21 UTC, Daniel Lovins, working on the Concept: Classification Scheme, added the definition (en) Property: Schedule of concepts and pre-coordinated combinations of concepts, arranged by classification (classification: activity involving the components of grouping similar or related things together, separating dissimilar or unrelated things, and arranging the resulting classes in a logical and helpful sequence).
NOTE: A classification scheme often also includes an index.
On Wed Mar 23 2016 at 20:20:43 UTC, Daniel Lovins, working on the Concept: Classification Scheme, added the definition (en) Property: A method of organization according to a set of pre-established principles, usually characterized by a notation system and a hierarchical structure of relationships among the entities. (From ANSI/NISO Z39.19-2015)
On Wed Mar 23 2016 at 20:18:21 UTC, Daniel Lovins, working on the Concept: Classes, added the definition (en) Property: are groups of resources having certain properties in common and therefore put together as members of one concept. Dublin Core Classes are the terms of the DCMI Type Vocabularies - e.g. dcmitype:Collection, dcmitype:dataset, etc. Dublin Core also defined [ http://dublincore.org/documents/dcmi-terms/#H6 Classes as DCMI Metadata Terms] - e.g. dcterms:Agent, dcterms:BibliographicResource, etc. Relationships between Dublin Core Classes and Properties are the following:Each property may be related to one or more classes by a has domain relationship, where the domain indicates the class of resources that the property should be used to describe.; Each property may be related to one or more classes by a has range relationship, where the range indicates the class of resources that should be used as values for that property.; For further information about domains and ranges used with DCMI Properties see Domains and Ranges for DCMI Properties Source: Dublin Core
On Wed Mar 23 2016 at 20:16:12 UTC, Daniel Lovins, working on the Concept: Authority file, updated the definition (en) Property To: A set of established headings and the cross-references to be made to and from each heading, often citing the authority for the preferred form or variants. Types of authority files include name authority files and subject authority files. (From ANSI/NISO Z39.19-2015) From: A set of established headings and the cross-references to be made to and from each heading, often citing the authority for the preferred form or variants. Types of authority files include name authority files and subject authority files.

Types of authority files include name authority files and subject authority files.
On Fri Mar 18 2016 at 19:50:43 UTC, Daniel Lovins, working on the Concept: Archive, added the definition (en) Property: Noun - Place where documents and/or records are retained
Verb - To place or store something in an archive
