2025 Metadata Models and Services Typologies in Digital Resource-Sharing Frameworks

Topics and Working groups

A continuation of the work started at last years’ Dagstuhl workshop. This will be led by Franck Cotton (the proposed co-chair of the W3C working group together with Albert Meroño Peñuela) and Darren Bell, the liaison between the DDI Alliance and the W3C.

Tools and Implementation

This group will be an umbrella group covering several different topics, some focused on documenting implementation approaches to the stand and others more focused on the development of tools. The group will be jointly led by Steve McEachern and Hilde Orten. It is expected that several sub-groups will emerge, but the degree of coordination between and among them demands suggests that managing them as a single larger group makes sense.

DDI-CDI and Other Standards

There are several initiatives ongoing which will address this general topic. Within the Modern Stats community, a major effort is now being made to map DDI-CDI and SDMX; the advent of CDIF requires coordinated use of a number of different standards in support of FAIR, and there is a need to have published mappings of DDI-CDI to other flavors of DDI as well. This group will be led by Flavio Rizzolo due to his involvement in many of these different efforts.

Qualitative Data

This group will essentially continue the work which has been ongoing since the Dagstuhl workshop last year, in a more intensive way. The group will be led by Noemi Betancort, the chair of the related DDI working group.
