Extensions are not an interoperable method for identifying the type of files, nor do they pretend to be. It is useful to some people to use .rdf for the file extension of RDF/XML files on their local machines, but on the Internet file extensions don't mean a thing (though browsers might try using them to guess at a files purpose if other methods fail, this should only be a fallback behaviour).

There is no institute where extensions can be submitted - and if there were they would soon run into trouble since the extensions are rather short and are used for all sorts of private-use file types. http://filext.com/ maintains data on file extensions in use - but it is an informative site only. It lists 9 different types of file using .rdf (although at least one of those is RDF/XML used in a specific application context).
