Adds support for ontologies to IFC Facilitates better integration of

IFC with other standards Greatly improve the usability of

The IFD API adds even more functionalityThe IFD API adds even more functionality

Ability to know who added concept, originally

Ability to tag every relationship between two concepts with a context

A context is a ”view” of the concepts. A context is a grouping of relationships between concepts. A context can be constrained for a given set of users, or be open for everyone

Ability to know the status of each concept (DRAFT, APPROVED, etc.)

Ability to set preferred name of given concept

A name can be preferred for some and not for others. Easier to use API

The complexity of the ISO 12006-3 model is hidden in the API The API is open and standardized and independent of

software or platform.

IFD, OWL and Topic mapsIFD, OWL and Topic maps

IFD – OWL (Web Ontology Language) ”Same” goal, different technologies

IFD has an EXPRESS meta model, OWL (RTF) is based on XML EXPRESS models can easily be converted to XML There exist OWL exports from IFD

IFD - Topic maps

very similar conceptually. ”concept” = ”topic” simliar ways of relating concepts by objectified relationships

IFD, OWL and Topic maps are complimentary technologies, Not compiting technologies
