Data Type Registries WG & #2


Group details

Chair (s): 
Secretariat Liaison:

TAB Liaison: 
Francoise Genova
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.

CODATA Data Science Journal Call For Papers: Research Data Alliance Results Special Collection

Dear members,

I’m writing on behalf of the editorial board of the CODATA Data Science Journal. I would like to recall the possibility to submit the outputs produced by this group for the special collection of CODATA DSJ on RDA Results. Publication fees will be covered by the EC project "RDA Europe 4.0".

Discussion document for DTR Breakout at P11


Attached is an updated version of the 'informal spec' document on Types and Type Registries that Giridhar sent around last fall for comment. I propose that we use this document to support discussion at the Breakout on Thursday (Session #6).

There will be a brief update on ISO interest in this topic at the Thursday Plenary session on Recommendations and Outputs.

Fwd: Form submission from: 11th Plenary Group Session Application Form

See below for the proposed agenda for a single breakout session at P11 for DTR2, submitted as a session request a few minutes ago. This is quite flexible and comments are welcome on the details. We are coming to the end of this group and need to discuss future RDA activities, if any, in this area. There has been a fair amount of uptake of the concepts, but more work is needed on standardization and best practices.
Thanks and I hope to see many of you in Berlin in March.

Informal spec on Types and Type Registries - soliciting comments

Hi All,

Thanks for attending the call held on Oct 9, 2017. And specifically for sharing your views on the technical direction question I raised. I have uploaded to this site a specification of sorts for types and type registries. Here's a link to that document:

Informal spec on Types and Type Registries - soliciting comments

The document is informal in nature and also has a few gaps to be filled. We will formalize the document in the next few weeks.
