Introducing IFD IFD - International Framework for Dictionaries IFD was developed and maintained 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 BARBi LexiCon SDC NBR IFC and IFD is harmonised through the work of XM-7 More information at: http://cic.vtt.fi/niai/technical/ifc_3/r3_projects.html Full support for IFD in IFC version 2x3g Freely Available on Internet Today
What is IFD? A conceptual... Multilingual concept oriented... Framework for ontologies with a plug-in for IFC
Conceptual, because.. IFD describes objects from what they are, independent of use and time, and not from what they are named or classified as. NS 3451 Building parts NS 3420 Building specifications Building product catalogue 2 Building 2.3 Outer walls 2.3.1 Primary construction 2.3.3 Windows, doors, etc 2.3.3.x Outer doors 2.3.3.y Outer windows Outer cladding and surface 2.4 Inner walls 2.4.1 Primary construction 2.4.3 Windows, doors, etc 2.4.3.x Inner doors 2.4.3.y Inner windows 2.4.5 Inner cladding and surface R.6 Doors, gates, sliding walls, trapdo 15 Wooden products and interior R.6.1 Doors 15/10 Bathroom panel R.6.1.1 Inner doors 15/20 Doors R.6.1.2 Outer doors 15/20/000 Inner doors R.6.1.3 Entrance doors 15/20/100 Outer doors R.6.1.4 Sliding doors 15/20/230 Sliding doors R.6.2 Industry gates 15/20/420 Entrance doors R.6.3... 15/24 Windows building, outer wall, inner wall, door, outer door, inner door, sliding door, cladding, outer cladding, inner cladding, surface, inner surface, outer surface, inner surface, artefact, interior...
Ontology, because.. IFD describes an concept by relating it to other concepts IFD includes properties and type values for concepts concepts can be referred to, though globally unique IDs inner door is a type door is a type of building product firedoor of is a type fire escape route is part of escape route of door consists_of door leaf door frame consists_of door sill door is part of doorway is part of opening in wall horizontal light-opening for door relates to with of escape route door can be inner door outer door sliding door rotating door consists of sliding door leaf sliding door frame strongroom door
Multilingual concept oriented, because.... what a dictionary gives as a translation of a word in one language not necessarily refers to the same object in another language. dør door door-set dørblad door
Multilingual concept oriented, because....because a beam is not just named beam bjelke beam truss balk ligger
Multilingual concept oriented, because....because a beam is not just a beam
How to know a door when you see one... Processes What do we mean by the with and height of a door? Idea/initialisation Execution Planning/detailed design Use, maintenance, administration Programming/conceptual design Rebuild, demolish Actors Owners Users Designers Contractors Suppliers Other Authorities Standards Environment Research
One object exist in multiple contexts In a briefing document IFD dictionary In a CAD system In product catalogues In a calculation system In classification systems In a Facility management system In building specifications For demolition and reconstruction

IFC / IFD / IDM one platform. Fits all IFC/IFD enables one common platform for: Knowledge databases Product databases Project databases Knowledge Knowledge and and rules rules can can be be formatted formatted in in a a way way that that enables enables automatic automatic control. control. Products Products and and product product properties properties carries carries the the unique unique identifiers identifiers from from IFD IFD dictionaries. dictionaries. Project Project information information from from different different phases phases of of the the project project is is stored stored on on objects objects and and object object properties. properties.
IFC / IFD / IDM used with knowledge IFD/Ontology Enrich the content by adding semantic making knowledge language independent uniquely identifying the concepts (GUIDs) Mark up the rules and exceptions Possilbe to convert to rules that can be executed on Ifc models
Adding semantic from ontologies enables: Two way links between different sources of knowledge Language independent interlinking of knowledge Linking of knowledge to material, products, elements... Multiple views to the same knowledge Context sensitive knowledge (wisdom)

Lessons learned in Norway Start with owners and motivate them by seeing the potential for improved sustainability (less energy consumption, less construction material usage, less waste ) Motivate medium-sized software developers through the new business opportunities Focus on seeing is believing demonstrate what is possible and stop talking Just Do It! Motivate government to see the potential for efficiency and freeing up resources for more value adding activities Motivate educational institutions to see the potential for new roles and new ways of providing knowledge
