The DDI Alliance and CODATA sponsored a workshop titled “Aligning Technology Architectures with Cross-Domain Metadata Models” held at Schloss Dagstuhl – Leibniz Center for Informatics in Wadern, Germany from October 6 to October 11, 2024. The main focus of the workshop was on the DDI-CDI specification, which is now going through the approval process at the DDI Alliance for its 1.0 release. Main topics focused on tools development and support for the specification, and future work within the group. This included some initial discussions with the W3C liaison regarding prospects for collaboration. The event was attended by 24 experts, including members of the DDI-CDI Working Group and the Qualitative Subgroup, members of the broader DDI community, and invited experts from the Dataverse community and relevant W3C committees. The work was organized around topical subgroups, which are described below. Overall, the event was a major success – each of the groups was able to meet their goals in terms of substantive outputs, and plans for further work established.
