Prefix OAuth properties ? i.e. as:client_id

Question

I am seeing a lot of people using "as" as a prefix for return items on OAuth for example

   as:client_id

Can anyone tell me what significance this has?

I don't see it in the OAuth specs

Thanks

In the examples that I found(Adding Refresh Tokens to a Web API v2 Authorization Server, OAuth Resource Password Flow Refresh Token with Web Api) that's just an example "key" to store the client_id in a dictionary local to the client for later usage.

By no means it is used in the interaction with the Authorization Server or as part of the OAuth 2.0 protocol itself.
