Editing Reification (computer science) (section)

=== In Topic Maps ===
In an [[Topic Maps|XML Topic Map]] (XTM), only a topic can have a name or play a role in an association. One may use an association to make an assertion about a topic, but one cannot directly make assertions about that assertion. However, it is possible to create a topic that reifies a non-topic construct in a map, thus enabling the association to be named and treated as a topic itself.<ref>[http://www.techquila.com/practical_intro.html Practical Introduction into Topic Maps] {{webarchive|url=https://web.archive.org/web/20090203202441/http://techquila.com/practical_intro.html |date=2009-02-03 }}.</ref>
