2010-09-13 Thread Laurens Van Houtven

[OAUTH-WG] Scope: why is the format predetermined?

2010-08-11 Thread Laurens Van Houtven
Hey, We have a use case for a scope that's more fine-grained/flexible than what you could explain in a set of space-delimited keywords. We would like to encode things like the precision with which some data can be accessed, and the scope sounds like the reasonable place to do that. Of course we
