Hi everyone,
About a year ago, I’ve been working on creating and improving decision-tree-style schemes for my local community. These include a road classification scheme, a heritage tagging scheme, and a name classification and tagging scheme, which also has an English version.
I’m now inspired to create another scheme in this style, but I’d like it to be as useful to the community as possible — not necessarily to the English-speaking community, but perhaps to one of the local communities.
This could include localization into other languages for different regions, as well as adaptations of schemes I’ve already worked on, for example those related to names or road networks.
So here’s my question: do you know of any non-trivial tagging systems in OSM that:
a) are fairly complex for newcomers to understand;
b) have some kind of hierarchy that would naturally lend itself to being presented as a decision tree;
c) represent a data category that is not yet fully covered in OSM and still requires further improvement and more complete mapping.
Maybe you already know of some existing schemes that could be taken as a basis and “updated” both in terms of content and design.
I’m specifically interested in a printable format, roughly A4–A3 (perhaps even A2), and not just in the Mermaid representation itself.
I’d be glad to hear your thoughts and suggestions!
Thank you!
