REST | OSLC : How to get workitem types, its workflow and then the actions possible in that workflow?
I am looking for some pointers to connect the workitem type --> workitem Workflow.
1. I use the workitem services URL to get the workitem types in a project area.. eg : https://clm.admin.ws/ccm/oslc/contexts/_u4qKYqUSEeOZfPTW9a4EhA/workitems/services.xml 2.1 I am interested in looking at the states / actions available in a particular workitem type. eg: https://clm.admin.ws/ccm/oslc/types/_u4qKYqUSEeOZfPTW9a4EhA/defect 2.2. The URL to which will be : https://clm.admin.ws/ccm/oslc/workflows/_u4qKYqUSEeOZfPTW9a4EhA/actions/com.ibm.team.workitem.defectWorkflow I am looking for pointers on how to get from 2.1 to 2.2 using REST/ OSLC. I tried various ways but somehow the workitem type and links to their workflows dont seem to have a continuum. Is there a sequential step to get from workitem type to its workflow link? -or- 1 place where we can look at both workitem types, and the links to their workflows? Thanks in advance... |

Hi Sunil,
At your step 2.1, check the work item "shape" rather than the type itself, namely https://clm:9443/ccm/oslc/context/_pz7gsD7rEeSp1IF8DHJaNQ/shapes/workitems/defect In the output, look for the "state" attribute and it should contain all the allowed state values <oslc:AllowedValues rdf:about="https://clm:9443/ccm/oslc/context/_pz7gsD7rEeSp1IF8DHJaNQ/shapes/workitems/defect/property/internalState/allowedValues">You also get the workflow id at the same time. Replace the "states" with "actions" in the URL and you will get all the actions in the workflow. https://clm:9443/ccm/oslc/workflows/_pz7gsD7rEeSp1IF8DHJaNQ/actions/com.ibm.team.workitem.defectWorkflow The challenge is to determine the allowed action(s) for a particular state, which does not seem possible with OSLC at this stage. https://jazz.net/forum/questions/152920/how-find-available-actions-to-change-states-in-rtc-with-oslc It is doable using Java API though. http://rsjazz.wordpress.com/2012/11/26/manipulating-work-item-states/ Sunil Kumar R selected this answer as the correct answer
Comments Donald, thank you. But using the 'shapes' URL gives me a 'HTTP 406 Not Acceptable' message with data..
<oslc_cm:status>406</oslc_cm:status>
<oslc_cm:message>OSLC Version '1.0' is not supported.</oslc_cm:message>
Could this be occuring due to missing header..? Thanks in advance.. 1
Yes it looks like an HTTP header is missing. Here are the two HTTP headers that I use most of the time for OSLC requests.
Accept: application/rdf+xmlIf you omit the "OSLC-Core-Version" header, the default "OSLC-Core-Version: 1.0" will be assumed. Thanks a lot Donald! Yes, I am able to get the data as expected using the header, steps above.
