Object Version Control for Collaborative Design Characteristics of the concept-modelling framework

In this paper we describe the main characteristics of the concept- modelling framework that is developed in the DesKs project on Design Knowledge services. Concept modelling gives end-users access to the schema of design models and provides a high level of flexibility for modelling. To support collaborative design, it provides remote data access and allows users to share active resources that, instead of being exchanged or stored centrally, remain at their source in tight relation with business processes. The concept-modelling framework implements object version control and uses timeline management of versions and revisions of objects to increase the integrity between objects that are accessed and edited by multiple users across a network.
