I have requirement artifact URI when fetch details of it using oslc i am not finding any details related to where it is getting used .
I want to find the Module where it is been used .
Similarly another scenario with Test case. I have Test case URI I want to find the Test Plan details of it.

Hi Vijayakumar,

At present we dont have any facility in Repotable REST APIs to show test plan details in the TestCase xml. Reverse is present. If you have the testplan uri then you can get the list of testcase uris linked to that TestPlan

Which RM provider are you using? Is it DOORS or Requirement Management or some other RM provider?

I am not so sure but that might not be possible directly from the requirement uri.
But you might use the OSLC queries to do that. If you are implementing this in DXL, then you can actually find out the module from URI. Standard OSLC query should allow that.
Check
http://open-services.net/bin/view/Main/OSLCCoreSpecQuery . Depending on query support of DWA, it might work

Reverse should be possible
. Requirement Collection should have list of requirements

Thanks a lot for the info :)

I am using DOORS .


vijayakumar ramesh commented Aug 18 '15, 8:12 a.m.

Just to be specific I am using DOORS next generation.

Similar to RM & CM oslc api's is it possible to program for the RQM. Because till now I have used REST Client in firefox to send OSLC API queries for RQM .I have got the results. 
I got this doubt because why there is only  RQM Utility Jar for RQM and not for CM or RM. Without using utility jar is it possible to program based on OSLC api's .

Is it same case with Requirement or any DNG artifact.
I know requirement artifact , from which I want to find the Module.

Thanks for the above info.

My example code might look like this: This is possible via REST Client in firefox why not I am getting same results here please share if you have sample code or suggestions where I have misunderstood something.I checked online couldnt find some workshop related to RQM for OSLC API's
