| In section 3.4.1 Identifying subjects, could you give me some exemples? It
| would help.
The new committee draft will have the following example:
Consider the URI http://www.topicmaps.org. If given as the subject
locator of topic A this would mean that topic A represents the
information resource identified by this URI. However, using it as
the subject identifier of topic B would mean that B represents what
is described in that information resource. At the time of writing
this would seem to be the organization known as
TopicMaps.Org. (Note: the organization; the real-world institution
known by that name. This is different from the subject of A, which
is the web page itself.)
Note the uncertainty in the last sentence above. The information
resource in question is a subject indicator for topic B, but it was
not written to be a subject indicator (that is, it is not a
published subject indicator), and so is not entirely unambiguous
with respect to what subject it indicates. Nor is it guaranteed to
be stable, so at the time of reading it may indicate some other
subject, or it may no longer exist.
Does that help? Feedback on whether the example is useful would be
very welcome.
