CONTEXT CAPTURING OF MULTI INFORMATION RESOURCES FOR THE DATA EXCHANGE IN COLLABORATIVE PROJECT ENVIRONMENTS

Abstract

This paper introduces a framework for context capturing of multi information resources and is based on the three major approaches which have been developed over the last decade. Having similar goals in mind they have come up with partially different objectives, methods and representation technologies. The three are, respectively, the Multimodel (MM) approach of the Mefisto project in Germany, the COINS approach in the Netherlands of linked documents and models and the Linked Building Data (LBD) approach of the Linked Data Group in Europe. They were developed in recent years to tackle the central problems of management and exchange of various types of data in a single package expressing a certain context and goal in an overall digital AEC environment. The differences and the commonalities of the first two approaches are addressed and the more future oriented LBD approach is compared to them. The related upcoming standard ISO 21597, pursuing a merging of the first two approaches in its Part 1, is discussed, whereas the third approach, targeting reasoning, will be a subject of Part 2 that is still under discussion.
