    Ontology contexts

    Contexts provide a domain-oriented way to enter the extracted corpus. Each page gathers the classes, object properties, datatype properties, SHACL shapes and SKOS schemes assigned to one graph-derived module, while keeping links to resources owned by neighbouring modules.

    PDTF schema contexts, not SPDTF authority

    These are module groupings in the draft schema-derived ontology. They are not approved SPDTF bounded-context models and do not confer working-group ownership. Read the SPDTF context method for the current evidence-up approach.

    How to read a context page

    LayerWhat membership tells you
    ClassesThe primary kinds, roles, relators and information objects documented in the module.
    PropertiesThe relationships and literal attributes assigned to the module; their targets may cross a context boundary.
    ShapesThe constraints grouped with the module. Shape membership does not turn a closed-world check into OWL semantics.
    SchemesThe controlled value spaces associated with the module, represented separately from OWL class hierarchies.

    Context membership is a navigation lens

    The pages expose how the committed model is partitioned; they do not assert that every relationship is local or that every resource has only one professional interpretation. Cross-context links are expected. The historical PDTF modelling record explains the earlier DDD framing, while SPDTF working groups must review meaning from attributed domain evidence rather than inherit this partition uncritically.
