Generalize OSM tagging model awareness and usage

Dear all,

OSM tagging model is continuously improving since the very beginning of the project and remain deeply linked to the way we map things.
According to several experiences, it could be a robust and inspiring structure for external databases as well. It may be a bit unpopular without some context I guess.

I had some ideas in mind for a few months and took time to write down them in a diary this morning.

Let’s discuss it there or in diary comments.

Best regards.
