Debbie,
There is a bit more at

It's worth reiterating one point in light of your inquiry: subject proxy 
objects  are the objects contained in a subject map. A subject proxy, 
itself, could be as simple as a database table the columns of which are 
propertyType and propertyValue (in the simplest possible rendition). 
Therefore, RDF is a reasonable way to represent the properties contained 
in a subject proxy.    (02)

Among those properties will be "name properties"; every knowable name 
for the subject represented by the subject proxy can be gathered 
together for each with some metadata such as language or usage or name 
type (e.g. acronym). With that organization, you can create a social 
bookmarking website such as Tagomizer or Fuzzzy and, at the same time, 
have a name be used without ambiguity in relation to many different 
subjects. Some names, e.g. "George Bush" can serve the proxies that 
represent both presidents and a tag with the same name. Each actual 
proxy carries a locator, the database identity, which, itself, could be 
a URI as has been discussed at length here. By separating names from 
identity, we are able to accommodate many uses for the same name string. 
Other properties facilitate disambiguation when a name string is used as 
a query.    (03)

IMHO, with that architecture, or at least attention to what that 
architecture offers as one creates ontologies, conceptual graphs, or 
other representation systems, one need not write any "design criteria" 
or even "building codes" for naming since the identification scheme is 
decoupled from naming conventions. Within subject/object identification 
schemes, I have no doubt that "building codes" will be appropriate. 
Please note that I am using the term "naming conventions" here in a way 
that seems vastly different from the way everybody else appears to use 
that term; indeed, I suspect that when the term "name" is applied to a 
concept, what is meant is "identifier". I use the term "naming 
convention" more as an oxymoron: the only naming conventions I have 
experienced appear in such contexts as, for example, giving the first 
daughter the grandmother's name as a middle name, following the 
appending of "jr", "II", etc to children who take a parent's name, and 
other naming practices. I'm waving arms and leaving a lot out here, but 
my intent is to show how I see "naming conventions" in the grand scheme 
of communications.    (04)

In terms of naming subjects, well, those come from everywhere and are 
just strings that are often ambiguous, as my experience with homeland 
security suggests.    (05)

In terms of identifying conventions, the story is quite different; names 
*can* serve in identification, but they often should not be the sole 
property associated with identity. My experience with Philippine 
Airlines giving my frequent flyer mileage to someone who was born on a 
different date strongly suggests their computer programmers don't know that.    (06)
