    SPDTF working groups

    Working groups are one canonical family inside SPDTF. Practitioners contribute evidence, language, examples and judgement; facilitators make that meaning reviewable and machine-readable. Registration or a generated page does not confer membership, consensus or standards authority.

    How the groups work

    The working-group member guide explains joining and access, Teams discussions, SharePoint source intake, meetings, model review and decision boundaries. It distinguishes current operating guidance from proposed lifecycle rules.

    A common workspace shape

    Each group works through the same review path, while retaining ownership of its local meaning:

    • charter, scope, competency questions and decision owner;
    • participation routes, evidence register and source handling;
    • glossary, dictionary, taxonomies, controlled vocabularies, resources and relationships;
    • candidate versions, open questions, feedback dispositions and change history;
    • coverage assessment, technical views and generated exports.

    Interoperability Working Group

    Interoperability is a peer of the domain and scheme groups, not a child of one group. Representatives agree only the boundary arrangements needed for exchange: a small common boundary, a context map, qualified mappings, and shared identifier, provenance, versioning and change conventions.

    The DBT Smart Data group is OPDA-internal, not government-established and cannot confer statutory status.
