| Resumen: | The focus of this paper is Collaborative Knowledge Sharing systems and how their usability can be improved by supporting of knowledge divergence occurrences. This approach recognizes divergence occurrence as a natural source of new knowledge in knowledge sharing communities. This paper presents a framework for sharing knowledge based on an explicit process model that governs and coordinates users’ actions. The process includes operations for externalizing new knowledge and making complementary or divergent knowledge public. This framework conceptualizes a knowledge sharing process-oriented groupware application which supports the development of a knowledge repository collaboratively. In order to show how this framework can be used, we have instantiated it by ontologies as a knowledge representation paradigm. Finally, Co-Protégé, which is a prototypical groupware application based on the framework, is introduced. -- Keywords: Knowledge sharing communities, collaborative edition, collaborative ontology edition.
