Many thanks to the active and productive working group members of the EUROCONFERENCE in La Londe les Maures. The need for task ontologies in interoperable GIS In this paper I argue that GIScience needs task ontologies in addition to domain ontologies to enable knowledge sharing and reuse for interoperable GIS. One of the main challenges for interoperable GIS is the sharing of semantic information and the intelligent reuse of services. Ontologies enable knowledge sharing. Task Ontologies enable reuse of services. In combination they enable the sharing of semantic information. Additionally, geographic Services using generic tasks or methods will be used more often than highly specialized services. I propose to model generic tasks within each application domain. The need for task ontologies in interoperable GIS 1. Tasks provide context for knowledge A task guides cognition and perhaps even perception of objects in a given situation. The reason for a task and the way we perform this task guide which parts of reality we look at and perceive.
