2. Lars Bjørkhaug, SINTEF Building and infrastructure Introduction to IFD and its connection to IFC IFD - International Framework for Dictionaries IFD - International Framework for Dictionaries EDIBATECLexiConBARBi …  IFD (ISO/DIS 12006-3) was developed by ISO/TC 59/SC 13/WG 6  IFD is an EXPRESS model standardised in ISO 12006-3  Several countries has started building dictionaries based on IFD  IFC have support for IFD information as of version Ifc2x3g  The Norwegian BuildingSMART project and STABU has developed a common WSDL interface (API) to a unified IFD library  BARBi and LexiCon is now harmonized in a common IFD library  USA and Canada has just signed an agreement to join the effort  Version 2 of the API freely accessible on: http://services.ifd-library.org/api/2.0?wsdl

3. Lars Bjørkhaug, SINTEF Building and infrastructure IFC version 2x3g IFC version 2x3g  Adds support for IFD and GIS systems and their descriptive data Building information models, GIS and ontologies - integrated IFC – Industry Foundation Classes IFC – Industry Foundation Classes  A complete building model  Implemented in a large number of tools IDM Information delivery manuals IDM Information delivery manuals  Formalised agreements of what to exchange, how and when. IFD (ISO/DIS 12006-3)  Adds support for ontologies to IFC  Facilitates better integration of IFC with other standards  Greatly improve the usability of IFC property-sets

4. Lars Bjørkhaug, SINTEF Building and infrastructure Give one concept multiple names in multiple languages Give one concept multiple names in multiple languages  Concepts are categorized as being either objects, activities, properties, actors, ativities, measures, groups or units.  In IFD a concept can have multiple names in the same language bjelke truss beam ligger balk pump Activity or process to pump Physical object a physical pump on a plant Functional object a pump as a functional object  … or one name can refer to multiple concepts What can IFD do? dør doordørblad  IFD captures what dictionaries normally don't. door door-set door door-set

5. Lars Bjørkhaug, SINTEF Building and infrastructure The 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.

12. Lars Bjørkhaug, SINTEF Building and infrastructure IFD, 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
