I'm not sure what you need exactly but maybe the Annotea topics could 
help here too? They are simple and users can create, publish and share 
them  easily. For instance, 
http://www.annotea.org/mozilla/testdada/tags.rdf has some tag topics 
that can be presented with Annotea Ubimarks e.g. in a topic hierarchy 

Topics can also be related to other topics, so this is a way to make 
connections to other people's tags if so wished.
