@kf6nux Any kind of relevant factual data can be submitted, really. Road-related things like parking lots are definitely part of it as well as tons of metadata for roads. Business hours are also possible to include.

However, things that rely on opinions are intentionally left out. Same goes for things that change rapidliy (like building sites that last like 1 month only). For more information, go to https://wiki.openstreetmap.org/wiki/Beginners%27_guide
