Issue #4: 11179 Data Element Terms

Team,

Here is the next issue from the 8/21 Registry TC review. It relates to
ISO/IEC 11179 data element naming concepts.

ISSUE:

Suppose we have the following ACC:

Employee | Telephone | Number

where:

Employee = Object Class
Telephone = Property Term
Number = Representation Tem

We can create an ABIE from this, making it "US"-specific - the telephone
number will be a "US" format. So we would have:

US = Object Class Qualifier
Employee = Object Class
US = Property Term Qualifier
Telephone = Property Term
Number = Representation Tem

Where the ABIE name is:

US | Employee | US | Telephone | Number

We believe it is important to include "US" as the Property Term
Qualifier rather than ommitting it, so it is clear *which* term (in this
case the Property Term "Telephone") has context applied.

The Object Class should always have a Qualifier applied to it in this
case, so the context is clear at the top level.

BUT CONSIDER THE FOLLOWING: What if it is US employee who is currently
working in Canada? We could have:

US | Employee | CA | Telephone | Number

So the "US" Object Class Qualifier would be correct (i.e. instead of
"CA"), because it qualifies the term "Employee", and the employee is a
"US" employee.

QUESTION: Do you concur with all of the above?

Suppose we had started with a modified version of the earlier ACC:

Employee | Home | Telephone | Number

where:

Employee = Object Class
Home = Property Term Qualifier
Telephone = Property Term
Number = Representation Tem

Now suppose we create an ABIE from this, making it "US"-specific - the
telephone number will be a "US" format. So we should have multiple
Property Term Qualifiers, as shown below:

US = Object Class Qualifier
Employee = Object Class
US = Property Term Qualifier
Home = Property Term Qualifier
Telephone = Property Term
Number = Representation Tem

QUESTION: What should the order be for the 2 Property Term Qualifiers? 

That is, should the ABIE name be:

US | Employee | US | Home | Telephone | Number

or:

US | Employee | Home | US | Telephone | Number
