rtc_cm:ownedBy is not returned in the results of oslc.select

Hi,

Please give me a suggestion about OSLC.

Environment:
RTC 3.0 ifix1.

I run sent query by GET method.

https://server:9443/ccm/oslc/contexts/_HrD3wJMXEeC_7KEYV0gOaQ/workitems?oslc.searchTerms="aaa2"&oslc.select=dcterms:identifier,dcterms:title,rtc_cm:ownedBy,rtc_cm:resolvedBy,rtc_cm:plannedFor,rtc_cm:state

Then following Response Body was returned.

Could anyone let me know what is considered as the cause that rtc_cm:ownedBy is not returned in the Response Body?
