It's true, but OSM wiki, the tool people like me who tries to learn how to do something uses says that: https://wiki.openstreetmap.org/wiki/Semi-colon_value_separator#When_NOT_to_use . Change the wiki please if it is not.
Wiki explains "In general *avoid ';' separated values whenever possible*. Don't use them in your mapping, and don't propose them on the wiki if there are better ways of representing things. This is because use of semi-colons as value separators is contrary to the aim of *keeping it simple* both for data *contributors* (mappers) and data *users*. For the sake of new contributors and anyone trying to *use* the data (people building software for rendering, searching, "find my nearest cafe" mobile apps, etc) we should minimise use of values with special characters. It is particularly important to (wherever reasonably possible) avoid ';' separated values in more important "top-level" tags. That is, tags which define what an element is." Is not Destination value also so important? Also there's some software who...does not support semicolon: "Mapbox Streets <https://wiki.openstreetmap.org/w/index.php?title=Mapbox_Streets&action=edit&redlink=1> replaces ; with a spaced em dash ( — ) in any name <https://wiki.openstreetmap.org/wiki/Key:name>=* or name:* <https://wiki.openstreetmap.org/wiki/Key:name>=* tag. For primary keys such as amenity <https://wiki.openstreetmap.org/wiki/Key:amenity>=* or shop <https://wiki.openstreetmap.org/wiki/Key:shop>=*, it considers only the portion up to the first semicolon and drops the rest." I think dropping data is not a good way of working with OSM :( Taginfo says also there's some destination:x in Germany. For example http://taginfo.openstreetmap.org/keys/destination%3A1 http://taginfo.openstreetmap.org/keys/destination%3A2 http://taginfo.openstreetmap.org/keys/destination%3A3 and so on... Also if you see the list in taginfo about destination values you will see only two in top20 list (well ,one is with comma so also there's some problems of standarization) from the most tagged values: http://taginfo.openstreetmap.org/keys/destination#values And if you search top100 list there are only 12 values with semicolon , 2 with comma . All these values together are only 1792 tagged values...from 71665 total values. I think one tag one value it is the best standard for traffic signs also to make it easier for the begginners and newbies. Cheers (Salut i senyals) yopaseopor
