Calling the operation of creating an RDF (or XML or HTML or SGML ...) tree 
from "parsing" is a gross distortion from what really is going on. As Dmitry 
says, it is much more a deserialization operation, since you don't need any 
sort of traditional parser to implement it. You just need text operations 
(lexical analysis) and a stack of pending tree nodes (both of which are 
needed even if you had used a traditional parser anyway). In general, any 
"language" where the node types are immediately determined (as in all of the 
above, the prefix determines the type of node) does not need parsing, 
because there are never any situations where the choice of what to do has to 
be deferred.
