[OSM-dev] Period In Key Names: Will It Cause A Problem?

Will a period in the key name for a tag cause a problem?
It is proposed in:
I would like to use it for some custom tags I am using, namely
"name.prefix", and "name.full" (see below for context). The idea is that
".prefix" and ".full" is closely tied to the primary "name" key, and
not some other forms of name such as "alt_name". If the properties applied to the
"alt_name" key than "alt_name.prefix" will be used instead, etc.
However, if the period will cause any sort of problem I will just use
underscore in its place. The underscore doesn't make the relation as
obvious, but its not a big deal.

I imagine the Ruby code is doing the proper escaping for text like this, but
you're right: definitely worth a message to the dev list.
Not that it matters too much to the majority of the OSM community, but a
period in the key name is invalid for most NoSQL-based systems (MongoDB in
