screen-id

Proposals for how to identify screens

There are very few universal identifiers, though there are some common identifiers.

• Almost every publisher has one (or more) internal, publisher assigned ids they use to reference screens (or "places advertising can run")
• Some publishers or exchanges may identify using units other than screens (spots in loops, inventory groups, different sections of a screen)
• Some 3rd parties (e.g. GeoPath, COMMB, Route, etc.) assign IDs to screens

Some possibilities:

1. A format/protocol for generating non-colliding ids?

e.g. com.publisher.screen123

Admittedly - this kind of approach somewhat assumes a standardized id for publishers :) But - that also seems like it would be a useful building block

Perhaps formatted as

|| Section || Format. || Example || Description || | ------------ | ----------- | -------- | ---------------------------------------------------------------------- | | Publisher ID | Reverse-TLD | com.pub | Reverse DNS of a gTLD (similar to OpenRTB's adomain that is | | Screen ID. | String | 12345678 | Format determined by the publisher, expected to be immutable over time |

Perhaps "Publisher ID" could also be a rating agency - e.g. org.geopath or something like that

2. Some kind of registry?

This seems... hard

3. Delegate to an existing standard?

e.g. we could start with 3rd-party rating... but that also seems hard
