Hello,

A few months ago I switched to the contact: tagging scheme for contact data. In this tagging scheme “contact:” is attached to the beginning of the tag. It is the newer version of the “normal” tagging. osm.wiki/Key:contact

In my opinion this is much more accurate and clear. On the one hand it is clear that this is contact data, on the other hand a much more precise specification is possible.

For example, many POIs have social-media pages that can not be meaningfully entered without this tagging scheme. Without this scheme, a new tag has to be created for every new social network, which could be shown by many clients only years later, if at all. With this scheme you can add any network or similar and every client knows immediately what it is.

This scheme is currently used at about 10%, but is not yet set by any editor as a standard (as far as I know).

In my opinion, it is time to switch to this tagging scheme. What do you think and did you knew this tagging before?

Best regards, Chris
