Simple Example for RQM through OSLC
One answer
Since the RQM REST API does not support filtering on any of the ID related fields, you are out of luck here with the field filtering. You may have to construct the resource URI to the test suite directly based on the ID. If you can GET this resource (with an HTTP 200 OK response), the test suite exists. If you get an HTTP 404 (Not Found) instead, the test suite does not exist.
If the test suite is imported from Excel or Word, it should have an external ID, then the resource URI is
https://clm/qm/service/com.ibm.rqm.integration.service.IIntegrationService/resources/<project>/<external ID>
Otherwise, the URI is
https://clm/qm/service/com.ibm.rqm.integration.service.IIntegrationService/resources/<project>/testsuite/urn:com.ibm.rqm:testsuite:<ID>
