Tourism is a tag that shouldn't be used as a primary.
Primary tags should be used to describe what it is, not whom it *might* be
used by.
what about tourism=information with it's several subtags? Seems to fit
perfectly IMHO as a primary tag.
What constitutes a primary tag?
One that is used in to solely describe an entity without any additional
sub-tags.
Tourism is an activity.
A museum needs a tag to describe it's physicality such as building=*, &
maybe building:use=*
Museums (& art galleries) are used by many people other than tourists.
To indicate that it might be of interest to tourists a sub key such as
tourism=yes could be used.
How should one know which tags are
considered primary when parsing the OSM database?
That's up to the parser. However putting tourism=art_gallery for example
gives no indication of what type it is:
Is it indoors or outdoors?
Is it in a building, marquee, greenhouse? etc.
