[sc34wg3] 5.4.3 Topic Characteristics
Sun, 16 Nov 2003 10:57:57 -0500
Working my way through the lastest draft of ISO/IEC 13250-2 and ran
across the following section:
************5.4.3 Topic characteristics***********
A topic characteristic is a topic name, occurrence, or association role
belonging to some topic. A topic characteristic assignment is a
statement that a certain topic characteristic belongs to a certain
topic. In the data model this is represented by the inclusion of an
information item representing a topic characteristic in the value of a
property of a topic item. Any topic characteristic assignment
constitutes a statement about the subject represented by the topic.
The properties of topic items that do not represent topic
characteristics are not statements about the subject; they are
statements about the topic. As such they are part of the topic map
machinery, rather than statements about the subject represented in the
**********/5.4.3 Topic characteristics***************
To test my understanding, let me fill in the topic characteristics and
non-topic characteristics to make sure I have everything in the right boxes:
With reference to 5.4.6 Properties, topic items have the following
1. [topic name]
3. [roles played}
4. [subject identifiers]
5. [subject locator]
7. [source locators]
Is this correct?
What has me puzzled is that I would take [subject identifiers] and
[subject locators] to be statements about the subject, in much the same
was as [topic name] or [occurrences]. True they have that "TM" machinery
feel to them but not any more so than any of the topic characteristics.
What is the basis for [subject identifiers] and [subject locators] not
being statements about the subject, assuming I have the distinction correct?
I may be missing a perfectly obvious reason for the distinction (or have
the distinction wrong altogether!) hence the questions.
Hope everyone is having a great day!
