  •  
    • Topic Maps provide “ a model and grammar for representing the structure of information resources used to define topics, and the associations (relationships) between topics. Names, resources, and relationships are said to be characteristics of abstract subjects, which are called topics. Topics have their characteristics within scopes: i.e. the limited contexts within which the names and resources are regarded as their name, resource, and relationship characteristics. One or more interrelated documents employing this grammar is a 'topic map'”
      (Quotation from the same document as A Gentle Inroduction, below.)
      This Virtual Library does not set out to give an exhaustive coverage of Topic Maps. It is concerned with Published Subject Indicators, one part of the whole TM spectrum. The aim of this page is to give a few pointers to resources on the Web about TMs, from these few it is hoped that the user can easily find the majority of Web-published material.
      The one contribution to being a more general resource on TMs is a modest 'dictionary' of acronyms (at the foot of this page).

  • Lars Marius Garshol's: Topic map links external link
    “This page links to useful sources of information about topic maps, a new ISO standard for organizing information. Topic maps are based on XML, but go far beyond XML in terms of what they can do to organize information. Here's what you'll find on this page: Introductions, Examples, Books, Discussion forums, Papers and presentations, Specifications, Software, Topic map sites”.

  • Survey of RDF/TM Interoperability Proposals external link
    “The Resource Description Framework (RDF) is a model developed by the W3C for representing information about resources in the World Wide Web. Topic Maps is a model for knowledge integration developed by the ISO. This document contains a survey of existing proposals for integrating RDF and Topic Maps data and is intended to be a starting point for establishing standard guidelines for RDF/Topic Maps interoperability.”
