I've read a great example of a WADL file. I've also checked out the WADL2Java tool.
But I can't seem to find a full spec of the WADL format. I have many unanswered questions, mostly dealing with how various parts of the file relate to one another and whether I can reduce duplication by using references.
Later
leppie got the official answer, but that document kind of sucks. Anyone have a better reference?
