Hi Kittipat,

So glad you're interested in the project!  Hi Peter, too.

There's a reason I proposed to limit the lowest tier to the Dublin  
Core Abstract Model.  There are metadata encodings in XML and RDF, and  
both have their uses and consumers, but roundtripping between them is  
neither trivial nor lossless [in particular, I'm interested in  
Learning Object Metadata, which has an accepted XML binding but not  
RDF yet].  So I proposed DCAM, from which XML and RDF could be  

Your other question was about a way to provide new methods should new  
metadata applications arise.  I'm thinking in terms of tiered  
architecture (PGF and TikZ is a good example).  I don't want authors  
to have to be metadata experts or to understand the underlying data  
structure.  If it's too complicated, nobody will use it.
