Using the same key with multiple values

OpenStreetMap Questions and Answers
#1

I’m editing a local library, and they offer multiple means of key:internet_access (wlan, terminal).

Would the proper tagging method be to use them comma separated, or have two instances of the key?

Example:

internet_access:wlan,terminal

vs

internet_access: wlan
internet_access: terminal

Again, thanks in advance for helping a new editor get it right!

I did some reading on the wiki, etc. Turns out the proper format would be:

internet_access:wlan;terminal

You should use semicolon instead of comma. You can use tag only one time in object, so the second solution will not work. More about multiple values you can read on Wiki: https://wiki.openstreetmap.org/wiki/Multiple_values

Although semi-colon separated multi-value is more common, there appears to be some using internet_access:wlan:*= sub-key for further details already.

#5

Should be internet_access=wlan;terminal

Good call - JOSM puts that in there, so I never paid attention to whether it was a : or =
