The development of very large ontologies may involve several domain experts, ontology engineers and final users, all with very different objectives. New scenarios like biomedicine, genomics and biology require methodologies that consider new dimensions in the development process, namely: dynamism, distribution and control. Existing works lack some important aspects with respect to these dimensions. In this paper we propose a view-based methodology for the collaborative, distributed and modular development of large ontologies, which achieves the identified requirements for the proper evolution and use of very large ontologies.
