Re: UCR issue 30: missing requirement

Hi-

Rachel is correct; 'Locating a thing' [1] (provided by @eparsons) is the
source of this requirement. The description provided in her message is
accurate. Ed also uses phrases like "upstairs", "where I left it" etc.

It's not about geocoding; it's about relating position in human terms ...
all about context.

FWIW, there are already some reasonable models from OGC about describing
relative positioning - usually related to position within a topological
network offset from a node in that network (e.g. position of signage on a
railway, position of a lamp post on a street etc.)
