WG Data Type Registries 1 & 2 - RDA 11th Plenary meeting

Meeting title

DTR2 - Conclusions and Future Steps (Remote Access Instructions)

Collaborative session notes:


Short introduction describing the scope of the group and if any previous activities

The DTR2 group has followed up on the work of the initial DTR group. The published output of that group, released at the end of 2016, is available as


The executive summary of that report states:

"The basic goal of this group was to aid data sharing efforts through improved data typing, specifically to make clear the details and assumptions buried in other peoples’ data. This was seen primarily as a problem in defining a data model appropriate to a wide potential collection of data types, prototyping that model in a registry, and developing a federation strategy across multiple registry instances, all following an analysis of use cases and related efforts."

Over the last 18 months or so the DTR2 WG has looked at various adoption efforts and the standardization of the concepts agreed to at the end of the initial WG, not yet coming to any conclusions. While this has gone on an ISO working group, one associated with the well-known ISO11179 metadata standard, began discussing the standardization of type records and has concluded that a new ISO Group will be started in 2018 to pursue this topic.
