RDF Ltd is a software company specialized in the area of parametric geometry and Semantic Web. The main work comprises of the development of complex kernels/components for other software companies and prototype end-user applications in case the target area is new and not well covered by other software companies. Typical examples of work done by RDF is the handling of 3D storage and operations (Constructive Solid Geometry, generated parametric geometry) for component libraries, fast and stable parsers and reasoners for Semantic Web standards. RDF Ltd. is performing internal research and development in the focus areas of ‘parametric geometry’ and ‘Semantic Web’. This includes work on reasoners on Semantic Web ontologies/knowledge but also parametric extensions of modern standards based on a previous technology like STEP, including AP203, AP214 and IFC (see also parametric IFC editor). This research is feeding/improving and financed by a small set of technical components that require license fees and support from other software companies using these components. Components created and supported by RDF are used by software vendors all over the world, Europe, United States, Asia and Australia.


Main roles in PROFICIENT

RDF is the WP6 leader. Together with TNO and DEMO we will develop the correct architecture to be used and develop technical components needed on the background and prototype end-user applications. RDF will also participate in the SME Council as a representative of SME’s in the ICT sector. RDF will also be involved in the SME Council and will actively contribute to demonstration and knowledge dissemination.


Key persons involved

Mr. Peter Bonsma MSc. (WP6 Leader) is the co-owner of RDF Ltd. and the technical architect of the components developed by RDF Ltd. He has a degree in technical mathematics. After working for many years on mathematical optimization algorithms and compiler development his focus changed to geometry and ICT standardization. Peter developed the basis of several ISO standards/proposals and is part of the Model Support Group of IFC, one of the main standards in the building and construction area. With more then 10 years of experience in geometry standards and development of a commercially used real time CSG algorithm, as well as a long history in Semantic Web, he is now focused as technical architect on complex technical components for other software companies.
