How to get list of all changesets using oslc-cm or oslc-scm
One answer
Guys got some general way of achieving the above problem, but I'm not sure it is using OSLC concept in it.
.com/ccm/service/com.ibm.team.scm.common.internal.rest.IScmRestService2/historyPlus?n=25&path=workspaceId%2F_Dh7kMAHIEeSZzL8CZgHcOQ%2FcomponentId%2F_j7JnAbl2EeOYP5vHPrH3vA
It returns the change sets without the need of workitem.
if any one find any other (using OSLC & not using API) way please post it here
