Hi,
I'm using DOORS NG (V5.0.2) and I'm trying to get requirements referenced by a RequirementCollection using OSLC.

I tried the query given on:

https://jazz.net/library/article/1197

which is:

&oslc.prefix=rdf=<http://www.w3.org/1999/02/22-rdf-syntax-ns%23>,dcterms=<http://purl.org/dc/terms/>&oslc.select=*&oslc.where=rdf:type=<http://open-services.net/ns/rm%23Requirement>

But this query only returns the RequirementCollection itself.

So, is the query correct?

Hi Carlos,

My understanding of the DOORS OSLC support is limited, but it looks like the query you're using returns all requirements for the entire project. So you're probably getting a collection that contains everything. You'll probably need to query based on the collection to get the requirements for that collection. The following query returns all requirements for a specific collection:

&oslc.prefix=oslc_rm=<http://open-services.net/ns/rm%23>,dcterms=<http://purl.org/dc/terms/>&oslc.select=oslc_rm:uses&oslc.where=dcterms:identifier=1

Hello Jim,

In fact, as you say, that query returns all requirements on a project. I was wrong with the query that I posted and the correct one is the query that you posted, i.e.:

&oslc.prefix=oslc_rm=<http://open-services.net/ns/rm%23>,dcterms=<http://purl.org/dc/terms/>&oslc.select=oslc_rm:uses&oslc.where=dcterms:identifier=1

However, this query only returns the RequirementCollection whose identifier is 1 and it does not return its requirements.

The solution that I found and it was supported by Jazz forum (https://jazz.net/forum/questions/200343/oslc-query-for-getting-requirements-from-a-requirement-collection) is to get the RequirementCollection and using the "uses" attributes (links to the associated requirements), which contain the requirement URL, we access to requirement info. by using REST commands.

I do not have better answer than this one. If someone has a better idea, I would appreciate.

Cordially,

Carlos
