Recommendations of the
ISO/IEC JTC1/SC34/WG3 Meeting
11 August 2001


1. Defect Report on ISO 13250

WG3 accepts N239 as the editors' response to the Defect Report (N238) on ISO 13250 submitted by Japan.

2. Topic Map Data Model

WG3 expresses its thanks to Lars Marius Garshol for preparing a preliminary requirements document (N241) for the topic map data model. The editors of ISO 13250 are requested to use this document as a starting point for a final requirements document for a model that expresses the fundamental nature of topic maps.

WG3 recognises that this model may have to be expressed at different levels in order to serve all its purposes, and therefore requests that the following work items be pursued in parallel with the finalisation of the requirements document:

  1. Development of a Core (Level 0) Model that defines the essential nature of topic maps at the lowest level and does not distinguish between association types. This work should use N243 as its starting point and take place under the editorship of Steven Newcomb and Michel Biezunski.
  2. Development of an Infoset (Level 1) Model, defined in terms of the Core Model (or with an unambiguous mapping to it), and additionally defining the semantics of topic-basename, basename-variantname, and topic-occurrence relationships. This work should use N242 as its starting point and take place under the editorship of Lars Marius Garshol and Graham Moore. While WG3 tends towards a preference for the Infoset as the modelling formalism for the Level 1 Model, other formalisms (e.g., Express, UML, or Z) are not precluded from consideration.

All four editors are collectively charged with responsibility for ensuring the complete compatibility of the two models.

3. Liaison with OASIS/TopicMaps.Org

WG3 proposes the establishment of a bilateral liaison with the new OASIS member group for topic maps, the former TopicMaps.Org, appoints Steve Pepper as its liaison for the meeting to take place on August 18-19 2001, and invites OASIS/TopicMaps.Org to appoint its own liaison to WG3.

4. Acclamations

Hosting of Meeting.

WG3 expresses its appreciation to the Graphic Communications Association/IDEAlliance for hosting this meeting of SC34's working group 3 in Montréal.
