The scope of the IOF is quite large and there will be many ontologies needed to meet the goals of the IOF. In order to facilitate a coherent and consistent development it is expected that there will be multiple ‘layers’ of ontologies where the ‘upper layers’ make use of the ‘lower layers’.
The roles of the Top-down Working Group are
- To control the development of different ontologies in the architecture. The IOF architecture is shown below.
- Formalize common core concepts and their notation.
- Ensure application of best practices for ontology development.
