  • A compact textual syntax for writing Topic Maps, handy when authoring Topic Maps in a text editor. (Linear Topic Map Notation (LTM))
  • A contribution to the debate on the "Identity Crisis" of the Web, showing how concepts developed as part of XML Topic Maps - in particular, the notion of subject indicators - provide an elegant solution. (Curing the Web's Identity Crisis: Subject Indicators for RDF)
  • A follow-on article for those that have already read "The TAO". This paper describes some of the basic steps in applying Topic Maps in a real world application, a Topic Maps-driven web portal of conference papers. (The XML Papers: Lessons on Applying Topic Maps)
  • A paper about schemas for topic maps from XML Europe 2000. It discusses the need for a schema system, gives examples of possible constraints that a schema could describe, and examines existing constraint mechanisms and their applicability to topic maps. The slides from the presentation are also available. (Creating semantically valid topic maps)
  • A paper from Extreme Markup 2001 that provides the first ever in-depth examination of the topic map concept of "scope": What scope is, how to use it, how it relates to "context", and not least how applications might take advantage of it when processing a topic map. (Towards a General Theory of Scope)
  • A paper from XML 1999 that contains an introduction to topic maps followed by a discussion of extended concepts such as topic map templates, type hierarchies, association types and constraints. (Topic maps: Introduction and Allegro)
  • A paper from XML Europe 2000 relating topic maps with semantic networks and conceptual graphs, and proposing a topic map query language (TMQL). (The answer is just a question [of topic maps matching])
  • A paper from XML Europe 2001 that describes a query language for topic maps called tolog. This query language is inspired by Prolog and fully supports the TMQL requirements. It has a clear and simple syntax, and its basic features are easy to implement. (tolog – a topic map query language)
  • A presentation covering the story of how Topic Maps has "taken off" in Norway — primarily as a vehicle for web portals in the public sector — and how this is paving the way for realizing the vision of "Seamless Knowledge". (Towards Seamless Knowledge — Integrating Public Sector Portals in Norway)

  • About how to deal with both topic maps and RDF. The paper shows how to do data conversion in both directions, how to convert RDF schemas to topic map schemas, how to use OWL with topic maps, shows how to do queries across both representations, and also shows how it is possible to have vocabularies that can be used with both topic maps and RDF. (Living with topic maps and RDF)

  • At TMRA 2010 it struck me that we&#8217;d never really documented or described the optimizations that we do on tolog queries, and so I thought it would be useful to explain that. I did this in a 5-minute presentation in the open space session, the slides to which are embedded below.<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=ontopia.wordpress.com&amp;blog=7947028&amp;post=300&amp;subd=ontopia&amp;ref=&amp;feed=1" width="1" height="1" /> (The tolog optimizations in Ontopia)

(Q: A unifying model for RDF and Topic Maps)
  • This paper describes an interpretation of scope based on the past few years of research on the subject. Based on this it defines two mathematical operators for scope filtering which correspond to common use cases for scope. (A Theory of Scope)

  • This paper outlines what is required of topic maps in order to gain the most benefit from them. A topic map architecture is described which covers a variety of information repositories. (Seriously capable Topic Maps)
  • This paper shows how topic maps can address the limitations of traditional content management systems while building on their strengths. The term ITMS (Integrated Topic Management System) is coined for a content management system based on topic maps, and the paper shows what is necessary to build such systems, as well as what benefits they bring. (Topic Maps in content management: The rise of the ITMS)
  • Trond Pettersen has written a small service to embed tolog in YQL (Yahoo Query Language), which he describes in a blog posting. Essentially, this takes a tolog query and the URI of a topic map, and produces JTM 1.1-like output suitable for further processing YUI3.<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=ontopia.wordpress.com&amp;blog=7947028&amp;post=326&amp;subd=ontopia&amp;ref=&amp;feed=1" width="1" height="1" /> (Ontopia and YQL)

  • We thought it might be interesting to show off one of the new features in 5.1.1: geotagging. Let&#8217;s imagine that you are making a map of pubs, as some of us do. The geographical location of a pubs is a very important piece of information to attach to it, so let&#8217;s do that. We create [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=ontopia.wordpress.com&amp;blog=7947028&amp;post=310&amp;subd=ontopia&amp;ref=&amp;feed=1" width="1" height="1" /> (Geotagging in Ontopoly)
