| 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.
