Joseph, I have to admit I am getting a bit lost as to what you are trying to define with this proposal. Whatever tagging we end up with, who is the target audience? What are the use cases? Is it an aid to interpreting and pronouncing the contents of the "name" tag? Is it a (strong) hint to mappers about how to synthesize multilingual labels? Is it documenting the official languages, or the popular spoken languages, or what?

Take Brussels for example. Officially bilingual for political reasons, in practice large parts are essentially French-only. Composite street names can be nl - fr or fr - nl. Can I suggest we work through Belgium as a case study, and when there is a proposal to suit Belgium, we then cross-check with e.g. Switzerland, Morocco, Spain or whatever?


If you want an extreme case then Papua New Guinea has over 820 languages.. all in one country.
They have 3 official languages, usage varies depending on what you are.
Documenting them would also be a challenge.
The amount of work vs the people who will use the data?
For PNG I don't see the work = the benefit.

Re: "How about "name:language_order=fr;nl"? No confusion possible there, whereas "name:language=fr;nl" would not specify the order, unless you define the list of languages to be an ordered list, which AFAIK would be a new concept to OSM." In Brussels they would actually like to be able to display the two languages neutrally, without a set display order. I don't think a display order specification is necessary. That information is already in the default "name=*" tag "Is it intended to be only for street names? If so, highway:name:language=* might be required to make that clear. Or does everything that can have a name need to fit in with this?"
Not only streets. Everything with a name=* tag has the same issues

        The idea is to allow a community to choose 2 languages to be
        displayed together as the default language setting, if so
        desired. If you check out the Multilingual Names wiki page
        <https://wiki.openstreetmap.org/wiki/Multilingual_names>,
        there are places where people choose to standardize the
        default name=* be a combination of two languages or two
        encodings; eg  fr + nl in Brussels, or Arabic + French in
        Moroco. If this is going to be adopted by the folks in
        Belgium, Morocco etc, there should be the choice of
        specifying two (or 3) languages, to fit with their current
        preference.

    How about "name:language_order=fr;nl"? No confusion possible
    there, whereas "name:language=fr;nl" would not specify the order,
    unless you define the list of languages to be an ordered list,
    which AFAIK would be a new concept to OSM.

        I'm not trying to change the way the default name=* tag is
        used, just trying to make it more useful by tagging what
        language is actually being used in the value for the name
        key. And I suspect there may be more communities that will
        choose this option, to encourage displaying names both in the
        local langauge and in the official or national language.

    So your idea is only for multilingual areas? Seems a bit of a
    waste. Combine this with "name:language=fr" in Wallonia,
    "name:language=nl" in Flanders, "name:language=de" in the
    Ostkantons, and "name:language=fr;nl" in Brussels?
    Is it intended to be only for street names? If so,
    highway:name:language=* might be required to make that clear. Or
    does everything that can have a name need to fit in with this?
