3. What can IFD do? Give multiple names in multiple languages
Concepts are classified as objects, activities, properties and units, not as verbs, substantives, adjectives, etc.
dør
door
dørblad
A dictionary based mapping does not necessarily refer to the identical concept.
door door-set
An concept can have multiple names on 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
A name can refer to multiple concepts

4. One object exist in multiple contexts

5. One concept carries the same unique identificatior in every language

6. IFC and IFD for exchange of data
IFC and IFD opens for 100% standardisation of exchanged data
IFD reference data
IFC propertyset
Information exchange on IFC format
IFC can also exchange self defined data through IFC property-set…
Self defined data
IFC propertyset
IFC ensure that data is exchanged as objects and object properties and not as lines and layers…
IFC can only standardise to a level of detail that is internationally agreed about…
The properties within an IFC property-set are not always standardised
IFC properties are not context independent…

7. Why is the integration of IFC and IFD important?
IFC + IFD enables one common platform for:
Knowledge databases
Knowledge and rules can be formatted in a way that enables automatic control of selected solutions towards best practice, rules and requirements.
Products and product properties carries the identifiers from IFD dictionaries. This allows for searches to be made based upon data from drawings, and specifications.
Product databases
Project databases
Project information from different phases of the project is stored on objects and object properties. Information can be filtered, edited and viewed in multiple ways.

8. Extended use of IFC and IFD, possible scenarios:
Research centres and suppliers of best knowledge:
Generic object databases with links to specification sheets and knowledge
Object databases with parametrical intelligent objects
Predefined solutions to drag-and-drop into CAD or specification software, etc.
IFC
Automatic control of selected solutions against best practise and regulations.
IFC
Centralised calculations of environmental impact
Calculations of life cycle cost and lifetime prediction
Certifications
Health and safety evaluation
IFC

9. Extended use of IFC and IFD, possible scenarios:
Standardisation- and specification organisations:
Mapping between national classification and specification standards and IFC data
Control of project data towards standards and specifications.
IFC
IFC
Automatic translation of standards and classification-tables between countries
Standardised views of project data through known hierarchies

10. Extended use of IFC and IFD, possible scenarios:
Product model servers (project hotels, project servers)
Possibility to exchange and update single objects. No longer need to send the whole drawing layer.
History of changes and reason for changes. Possibilities to set access rights for particular actors.
One project can be visualised in multiple ways; as drawings, specifications, calculation, estimates, etc.
Functional demands, technical solutions and product information stored on the same object.
IFC + IFD
product model
Reuse of information throughout the life-cycle of the building
Extracts of essential information from product models; escape routes, room functions, load bearing walls
Particular information to and from building authorities
Materials and product used
Facility management information
Guaranties and maintenance information …
IFC + IFD

11. IFC + IFD Demos Lifetime analysis
Focused search into Byggforsk Knowledge Base
Sound analysis
