GRDDL transformation repository?

An older version of the GRDDL spec (http://www.w3.org/2004/01/rdxh/spec) 
mentions a grddl-hg repository, but that link no longer works, and it's
not mentioned in the most recent version of the spec. Is there any list of
GRDDL transformations longer than the one shown at
http://www.w3.org/2004/01/rdxh/spec#implExp?

thanks,

Bob
