RTC OSLC query to filter only tasks from workitem

Question

How to filter workitems by tasks in OSLC api, I've tried the following queries but none of them is working

https://rtcserver/ccm/oslc/contexts/somekey/workitems.json?oslc_cm.query=dcterms:type=task

https://rtcserver/ccm/oslc/contexts/somekey/workitems.json?oslc_cm.query=dc:type=task

https://rtcserver/ccm/oslc/contexts/somekey/workitems.json?oslc_cm.query=type=task

Answer 1

You need to URL quote the query content, for example your attempted/hypothetical query URL:

https://rtcserver/ccm/oslc/contexts/somekey/workitems.json?oslc_cm.query=dcterms:type=task

Has to be encoded for actual use as:

https://rtcserver/ccm/oslc/contexts/somekey/workitems.json?oslc_cm.query=dcterms%3Atype%3Dtask

For more details/background see the OSLC query specification https://open-services.net/bin/view/Main/OSLCCoreSpecQuery - look for the section at the bottom "URL Encoding"

The example there, just for the parameter part of the URL is::

Not encoded:

?oslc.where=dcterms:title="test case 1" and dcterms:modified>="2008-12-02T18:42:30"

Encoded:

?oslc.where=dcterms%3Atitle%3D%22test%20case%201%22%20and%20dc%3Amodified%3E%3D%222008-12-02T18%3A42%3A30%22
