URI templates

URI template syntax

But we have RFC6570, why another one?

Current implementation have more questions than answers:

  1. It describes only template expansion, not matching. While URI matching is more common task (routing) - any template standard which doesn't describe matching will fail
  2. The RFC6570 modifiers sometimes is pointless and create more pain than gain for developers
