Data Type Registries WG & #2

Case Statement: 
WGs Maintaining deliverables (maintenance group)

DTR WG activity is currently paused while the topic of data type registries is under consideration by ISO as a potential standard. The next step in DTR work is clearly governance, regardless of the outcome of the ISO work, but if and when an ISO group comes into focus it will strongly influence the proper next steps for the RDA group. A likely outcome is the creation of the third version of the DTR group to work on governance, either in collaboration with ISO or independent of it.


The first two iterations of the DTR WG developed the concept, drafted a data model and expression for types, and then collected use cases to analyze the results. A number of data type registries are currently in use in prototype efforts, details of which can be found in the reports of WG sessions at prior plenaries, the last one of which was P11 in Berlin.



The output of DTR Groups 1 & 2 was approved as an RDA endorsed recommendation and was then accepted as an ICT Technical specification.

New Scholar for the Working Group


I'm happy to note that Mostafa Elag - a postdoc from UIUC - is going to be part of our group for roughly six weeks. He is a scholar assigned to our group by RDA as part of the RDA Intern Program.

I've asked Mostafa to have technical discussions on this group list versus communicating one-on-one with me or others. This way the whole group can be involved.

Here's what I have asked Mostafa to aim for in the next six weeks:

DTR at P4 (Amsterdam)


The DTR breakout session(s) in Amsterdam will close this group and the co-Chairs welcome any comments on what we should try to accomplish in that session or sessions. It may seem early to discuss this, but the P4 organizers are soliciting this information now.

A few things to consider:

Data Type Registry First Prototype


Here's a link to the first instance of the Data Type Registry: An example of a type record is here:

The documentation menu has links to the REST API document and the Q&A document I forwarded a few weeks ago. A few items to note:

ITU-T X.1255

I've just uploaded to the RDA File Depot a recently approved ITU standard relevant to this group. Its title, "Framework for Discovery of Identity Management Information' does not convey the relevance so I'm adding this note. It lays out the Digital Object Architecture, including types and type registries, as the underpining of the 'Framework' which puts it into a referenceable techncial standard. It also includes a number of definitions which I will add to the mediawiki.
