 I've been attempting to create artifacts against RTC 6.0.x that include links with labels. Questions such as https://jazz.net/forum/questions/151611/using-oslc-api-to-create-a-workitem-with-a-relatedartifact-type-of-link indicate this is possible but I haven't been able to make this work.


An example body of a POST request to a URL like "https://my-server:9443/ccm/oslc/contexts/_4ApvgFlDEeaDHtB25fULWg/workitems/task" (using header "OSLC-Core-Version: 2.0") creating a new artifact with a link:

<rdf:RDF
   xmlns:dcterms="http://purl.org/dc/terms/"
 <j.0:task>
   <dcterms:title rdf:parseType="Literal">Test artifact including a labeled link</dcterms:title>
   <j.2:tracksChangeSet rdf:resource="https://example.com/path/ada74a3d-164c-4a89-b9f2-4fd44fbfe550" j.2:label="special link label"/>
 </j.0:task>
</rdf:RDF>

When I use a Content-Type header value of "application/x-oslc-cm-change-request+xml", I get a 415 response with the message "Content type 'application/x-oslc-cm-change-request+xml' is not supported.".

When I use a content type of "application/rdf+xml" I get a 500 response with the message "null for literals has been illegal since Jena 2.0".

Should something like this be possible? Is there an error in my request, or a workaround?

Cheers

I can include a link in the creation without any problems but not the label. I have the impression that the label is automatically generated. Forget about OSLC for a moment, how can you add a linked item with a custom label?

 Currently you can create links while creating a work item using OSLC apis but you cannot create labeled links, in the xml you have posted, if you remove  j.2:label="special link label" then it creates a new work item with the link for the remote change set. Is this something that would work for you or do you need the label as well?

 Thank you, Sharoon. Being able to write the label is the key functionality I was hoping for; we are already creating work items with unlabeled links. It sounds like writing links with labels is not currently possible; thank you for confirming this.
