Will a period in the key name for a tag cause a problem?
It is proposed in:
http://wiki.openstreetmap.org/wiki/Proposed_features/Tag_structures
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'm not going to do this. Instead I am going to simply remove variants
on
"name" (for example all other names in the "900 East" example). And than
leave all other name_* and *_name alone (i.e. name_1, alt_name, etc).
When
the alternate name is a numbered street, it will get the ".prefix" and
".full" tags. For example:
name: Lorna Circle
name_1: 3805 South
name_1.prefix: W
name_1.full: West 3805 South
Whoa. Are you considering adding a period "." to the key? Might that
mess up postgres? From
http://www.postgresql.org/docs/8.2/static/sql-syntax-lexical.html
"The period (.) is used in numeric constants, and to separate schema,
table, and column names. "
Perhaps bounce some of these ideas around on dev?
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
particular).
