RDF, SPARQL and Ontology Interfaces

Verification boundary: This page combines platform design guidance with static evidence from the release. It does not prove that every detected interface is enabled, reachable, secure, or operational in the deployed environment.

SPARQL service contract

• Query endpoint, update endpoint and graph naming/version policy.
• Authentication and separate authorization for read, write and ontology administration.
• Timeout, row/result limits, expensive-query controls and audit.
• RDF serialization/content types and stable namespace registry.
• SHACL/constraint validation behavior and treatment of invalid statements.
• Backup/export, provenance and ontology migration procedures.

Example query pattern

PREFIX op: <https://example.invalid/openc5isr/ontology/>
SELECT ?entity ?observation ?time
WHERE {
  ?observation a op:Observation ;
               op:observes ?entity ;
               op:observationTime ?time .
}
ORDER BY DESC(?time)
LIMIT 100
