NAME
XTM - Topic Map, base distribution
SYNOPSIS
use XTM;
$tm = new XTM; # creating an empty map
# reading a topic map description from an XML file
use XTM::XML;
$tm = new XTM (tie => new XTM::XML (file => 'mymap.tm'));
# application specific persistent medium
$tm = new XTM (tie => new XTM::Application::MineMineMine);DESCRIPTION
Topic Maps are a means for layering multidimensional topic spaces on top of information assets. The standard covers concepts like topics, associations, scopes and occurrences. Topic Maps are expected to have a major impact on future information systems and compete with RDF in the semantic web arena.
See http://www.topicmaps.org/xtm/1.0/ for more information.
Topic maps can be loaded from an XML based resource (local or remote via an URL) as prescribed by the XTM standard. There is also a way to tie a map to any persistent medium. The latter is especially interesting when running this module along with a (web) server.
