## 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

```sparql
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
```
