calling a label name

Hi guys!

I think I have a pretty easy question for you. While I'm in a blog, there are a list of topics that I can click on. If I click on the topic, the page returns only articles related to that topic.  At the bottom of the entry is the text "Topic:" plus the name of the current topic - which is related to the label, correct? is there a way to return the name of the current topic through REST? Something similiar to coreNode.id? Maybe something like currentTopic.id?

Thanks so much! I appreciate your time.
