[closed] Using OSLC API to create a workitem with a relatedartifact type of link

RTC405 used

Referring to https://jazz.net/wiki/bin/view/Main/ResourceOrientedWorkItemAPIv2#Adding
a_Comment_to_a_Work_Item

We want to use POST to create a new workitem with a relatedartifact(in this case build result).
We tried the below xml file
===
<oslc_cm:ChangeRequest
    xmlns:oslc_cm="http://open-services.net/xmlns/cm/1.0/"

curl command:
> curl -D - -k -b %COOKIES% -H
"Content-Type:application/x-oslc-cm-change-request+xml" -H "Accept:
text/xml" -X POST --data-binary
"@.\ConfigBuildTrackingWI_with_relatedArtifact.xml" %URL%
>new_task_temp.txt

When running, got the error like
<oslc_cm:status>400</oslc_cm:status>
<oslc_cm:message>missing the required parameters:

http://www.w3.org/1999/02/22-rdf-syntax-ns#resource</oslc_cm:message>

It seems the error is related to the link we tried to add:

<rtc_cm:com.ibm.team.workitem.linktype.relatedartifact.relatedArtifact
rdf:resouce="
https://%HOST%:9443/ccm/resource/itemOid/com.ibm.team.build.BuildResult/_Cs_FodwrEeOQYtqUlaSvVg"
oslc_cm:label="my label"/>

The question is:
1) Does OSLC API allow the user to add link to the workitem when it is created using POST or we have to create WI with POST first and then use PUT to add the link to the created WI?
2) If link can be added to WI when it is created, what could be wrong in the above XML?"
Appreciate if anyone can shed some lights on this questions. Thanks a lot.
