How to search tag element of Rhapsody model on RDM 4.0.2 using OSLC API?

Hello,

When I find e.g. a class  by its class name in Rhapsody model on RDM 4.0.2 using OSLC API,
it works using following parameters.

oslc.select=*
oslc.where=rdf:type=<http://jazz.net/ns/dm/rhapsody/uml#Class> and dcterms:title="class_0"

But it does not work in case of tag.
oslc.select=*
oslc.where=rdf:type=<http://jazz.net/ns/dm/rhapsody/uml#Tag> and dcterms:title="tag_0"

And also does anyone know the way to search by tag value?

Thank you in advance,
Yukihiro
