Annotating realworld objects

Hi All,

I've been reading the webpages and the specs and it seems that the oa 
ontology looks very usable for my use case, I can make statements and 
classify these statements.
The only issue I have is that I want to make the annotations on real world 
objects, e.g. buildings. These real world objects do have a RDF Resource 
describing them.
My questions are: 
- Does os allow to annotate real world objects which have a RDF 
representation?
- Are there some hints / tips or best practices that would fit such a 
case?

Looking forward to the answer / discussion already

Met Vriendelijke Groet / With Kind Regards
