[tmcl-wg] Doubts in TMCL Requirements

[Giovani Librelotto]

Hi everyone,

I was reading the TMCL Requirements <URL:
http://www.isotopicmaps.org/tmcl/requirements.html> when I don't understand
some use cases, in section 4.1.2 (Constraint by topic).

U1. Valid topic names
---------------------
a. Topic of type T must have a specified number of explicit names
(cardinality). 
Example: Topic of type person must have two explicit names, i. e., one is a
nickname and the other is the full name.

==> Will TMCL specify a number of names, the content of baseNameString, or
both?


U3. Valid subject indicator 
---------------------------
(b). Topic of type T must have one subject indicator.
Example: Topic of type project must have at least one subject indicator no
matter what the value is.

(c). Topic of type T must have a subject indicator in scope S.
Example: Topic of type person must have a subject indicator in scope
social-security-number.

(d). Topic of type T must have a subject indicator of type O.
Example: Topic of type country must have a subject indicator of type map.

==> Please, could you give me short XTM examples for this three cases? For
each use case, a valid topic and a invalid one.

Sorry for the newbie questions.
Best regards,

Giovani
