You have a point… :-) The wiki already presents the idea that unknown means "unclear". [2] Taginfo tells access=unknown has 20 thousand occurrences (i.e. 0.30% and ranking at the 11th position), which makes it not so unusual. [3] The discussion here shows the value of "unknown" raises confusion

Hi, Is 'unknown' really such an unusual and undesirable as an access tag? I thought it was long-established, if not especially common. If the issue is a lack of Wiki documentation that is easily solved. I think that highway=footway foot=unknown adds a useful level of nuance. For example a routing

I'd rather use fixme and note tags instead of encoding uncodified information in well-established tags. The wiki page [1] explains a bit the difference: "The fixme key allows contributors to mark objects and places that need further attention. These can be in the form of a "note to self" or req

Hi all: I was the one who organized the import of 14,000+ places nodes in Liberia back in September 2014. The idea of giving place=unknown (together with a fixme=* tag) to places that were not possible to determine its value was proposed during the discussion in the imports list [1] [2]. p

Maybe they should be converted into a fixme=* value then, such as fixme="unknown maxspeed;unknown foot access;unknown wheelchair accessibility". Though I've always assumed that an absent tag means its value is unknown, so foot=unknown and no foot=* whatsoever would mean the exact same thing. Some

Others already gave possible causes, so I won't add or repeat. It's pointless tagging and leaves us guessing whatever it could mean. If your analysis shows these tags don't add value (this is to say: don't make a gigantic update on places you haven't reviewed), you better remove them (possibly

(Without digging through the database) I suspect that might be caused by the idea of default values... Imagine drawing a road. If you don't tag it as 'oneway', it is assumed not to be a 'oneway'. If you honestly don't know, you need to tag it with something like 'unknown'. But that's just my guess
