       TM::ResourceAble - Topic Maps, abstract trait for resource-backed Topic Maps


          package MyNiftyMap;

            use TM;
            use base qw(TM);
            use Class::Trait ('TM::ResourceAble');


          my $tm = new MyNiftyMap;
          $tm->url ('http://nirvana/');

          warn $tm->mtime;

          # or at runtime even:

          use TM;
          Class::Trait->apply ('TM', qw(TM::ResourceAble));
          my $tm = new TM;
          warn $tm->mtime;


       This traits adds methods to provide the role resource to a map. That allows a map to be
       associated with a resource which is addressed by a URL (actually a URI for that matter).

   Predefined URIs
       The following resources, actually their URIs are predefined:

           Symbolizes the UNIX STDIN file descriptor. The resource is all text content coming
           from this file.

           Symbolizes the UNIX STDOUT file descriptor.

           Symbolizes a resource which never delivers any content and which can consume any
           content silently (like "/dev/null" under UNIX).

   Predefined URI Methods
           An inlined resource is a resource which contains all content as part of the URI.
           Currently the TM content is to be written in AsTMa=.


             inlined:donald (duck)


       url $url = $tm->url

           $tm->url ($url)

           Once an object of this class is instantiated it keeps the URL of the resource to which
           it is associated. With this method you can retrieve and set that. No special further
           action is taken otherwise.

           $time = $tm->mtime

           This function returns the UNIX time when the resource has been modified last. 0 is
           returned if the result cannot be determined. All methods from LWP are supported.

           Special resources are treated as follows:

               always has mtime 0

               always has an mtime 1 second in the future. The idea is that STDIN always has new

               always has mtime 0. The idea is that STDOUT never changes by itself.
