The NetworkedPlanet Topic Map Fragment XML Schema provides a way for web service applications to transmit a small subset of a topic map as a list of topics. Compared to XTM, the Topic Map Fragment schema is easier to process both for reading and for updating topic data as all of the information relating to a single topic is contained inside one element instead of being spread out across multiple separate elements in the same document. This schema is used by several of the methods of the NetworkedPlanet Topic Map Web Service.

The W3C XML Schema representation for this namespace is also in the TMCore distribution and can also be downloaded from the NetworkedPlanet website.
