    Standards profile

    The candidate records both what it targets and what it does not yet claim. This avoids turning an implementation compatibility result into an unsupported conformance claim.

    Profile claims

    Full Union profile
    not claimed until a qualified implementation passes the required feature matrix
    RDF
    RDF 1.2 Basic authoring profile with explicit VERSION labels
    SHACL
    SHACL 1.2 Core target; emitted constraints use the implementation-tested Core subset
    SPARQL
    SPARQL 1.2 target; competency queries use the portable basic graph-pattern subset

    Assurance boundary

    No full Union-profile claim

    not claimed until a qualified implementation passes the required feature matrix

    The technical validation page records the actual tested implementation and subset. Standards targets can be broader than the features exercised by one candidate corpus.
