Reading RTC data from Focal Point using OSLC

I've linked an element in Focal Point to two elements in RTC and I want to display the state of the RTC elements in Focal Point by fetching the data through oslc.
The output should be something like:
RTC_elem1_title: state1
RTC_elem2_title: state2

So far I've managed to get either e.g. a combination of the titles and description of the elements
(using: "https://10.31.10.20:9443/ccm/oslc/workitems/10/?oslc_cm.properties" and XPath "concat(string(//dc:title),': ',string(//dc:description))"
or the state of the elements by itself, which is an enumeration
("https://10.31.10.20:9443/ccm/oslc/workitems/10/rtc_cm:state/?oslc_cm:properties" and XPath "concat(string(//dc:title),' ')"

So the question is, how can I get a result combining the title of the element and its state?

In the element, the state is expressed as:
rtc_cm:state rdf:resource="https://10.31.10.20:9443/ccm/oslc/workflows/_v7FCYLHgEd-doYgDpyNgaw/states/com.ibm.team.workitem.planitemWorkflow/51"
