@ToastHawaii Hmm the meaning of this field seems ambiguous on these… I could also assume it refers to who can view or approach the feature.

@quincylvania Thanks for pointing that out. I add the visibility tag and moved the access tag to the more field section. I think this helps to improve the clarity.

Both are part of the documentation on the wiki pages eg. for board https://wiki.openstreetmap.org/wiki/Tag%3Aadvertising%3Dboard. The access property was add for 3 years.
Based on the taginfo the access tag is used many times in comination mit advertising https://taginfo.openstreetmap.org/keys/advertising#combinations

Do you think it needs more? Is there anything I can do to make it less ambiguous?

@ToastHawaii Okay, if people are using this tag then it seems okay to have it under moreFields. Thanks for understanding 🤙
