I don't think anything uses it. I put that in there on the assumption that you wouldn't always be able to do point to point communication, so you'd need some kind of typing. E.g., if you put that on a message bus, you need some way to know what kind of document it is. REST is all about talking to specific end points, and we expect the caller to know where to send each kind of document, so it ends up not being used. This was supposed to turn into an envelope format that allowed us to version the data structures and such, but it doesn't look like it ever evolved into that. No idea if this is because we've never changed the formats, found another means of versioning them, or what. -- http://puppetlabs.com/ | http://about.me/lak | @puppetmasterd -- You received this message because you are subscribed to the Google Groups "Puppet Developers" group.
