The widespread use of mobile devices is leading to a next generation of applications that exploit user contextual information to provide a richer experience. One of the activities to perform during the development of these context-aware applications is to define a model to represent and manage context information. Currently, there is a lack of consensual models, and this supposes a handicap when developing these applications. This paper presents a context ontology network to model context-related knowledge that allows adapting applications based on user context. We describe the methodological process followed during the ontology development as well as the ontology network obtained from this process. Besides, we provide an example of how to extend the ontology for a particular use case in a concrete domain
