A Topic Map Data Model: An infoset-based proposal

Proposal, was published by Lars Marius Garshol and Hans Holger Rath at 2001-06-18

This document defines an abstract model for topic maps.

This document defines an abstract model for topic maps which makes explicit the implicit data models of ISO 13250 and XTM 1.0. It also defines a processing model for XTM 1.0 based on the data model.

The model is intended to present one possible approach to specifying a data and processing model for topic maps, believed by the author to be preferrable to other proposed approaches. It is hoped that this model may represent a first step on the way to a complete model for topic maps. Such a model would serve many purposes:

  • Enable interoperability between topic map processors by defining precisely what topic map processors are required to do.
  • Enable ancillary standards to be built on the topic map standard in a precise and controlled manner.
  • Make it easier for newcomers to topic maps to understand what their abstract structure is and how they work.

This document is not complete; it is an early draft intended to show a possible approach to defining the topic map model. In particular, this document has no official standing whatsoever. It is, as stated above, just a draft proposal.

Topic Maps is the only formal semantic model which is optimized for humans, not for computers. Applications and web portals based on Topic Maps are easy to use, without limitations for flexibility and creativity.
