Well AppID is a concept in Click and the system more than scopes. It is
the name of the package and the hook ID. It is, for instance, what the
name of the apparmor profiles are. But, yes, the same thing.

$(package)_$(hookname)_$(version)

For instance, you can get this value if someone talks to you and you ask
AppArmor what profile the connector is using.

At some level, I don't really care about the implementation, but in
other situations I've found just checking to see if a file exists in a
cache'd path is fast any easy to implement things like this. For
instance:

if [ -e ~/.local/share/unity-scopes/$(appid) ||
-e /usr/lib/*/unity-scopes/$(appid) ] 

Would probably work well enough.

Title:
  API needed to determine if App ID is a scope

Status in unity-scopes-api package in Ubuntu:
  New

Bug description:
  
  There are a few cases where we'd like it if a higher level service could determine if a particular AppID is connected to a scope. This mostly deals with requests that relate to trusted session prompts as they need to be overlayed on top of the dash instead of the calling process. Another is so that URL dispatcher can return better errors on the scope:// URL namespace. I don't think that it needs to be complex, roughly something like this:

  bool isScope (const char * appid);
