Semantic Mediawiki: Using semantics in a different namespace?

Question

I have one page (called PageA) created in the default Main namespace where I used {{#set:var=val}} syntax to set a property in the page. I'm able to see that property in the "browse properties" page.

Now, I need to move this page to a different namespace called NewSpace:PageA. It seems like that semantic is now broken because I'm not able to see that property in the "browse properties" page. This causes the #ask query to fail too.

Is there a way for me to add semantic to pages in different namespaces?

Thanks much.
