No way to advertise an interface?

[Anders Feder]

Sorry for the ambiguity, I meant interface in the general sense - MPRIS
defines a programming interface and one part of that interface is the bus
name prefix that MPRIS requires services to use. I will use the term "API"
instead:

I'm not saying that multiple peers can't implement the API. I'm saying
multiple peers can't implement the API with the assurance that they are not
causing a naming collision. This negates the purpose of having reverse
domain name notation namespaces in the first place.

If a person A creates an application named "Music Player" and have it take
the bus name "org.mpris.MediaPlayer2.musicplayer", there is no procedure
preventing a person B without knowledge of person A's application from
creating another application named "Music Player" also taking the bus name
"org.mpris.MediaPlayer2.musicplayer".

What better pattern, if any, could a standard such as MPRIS use to avoid
this sort of collision?

Anders Feder
