Ontologies describe the things that exist in a domain. This includes properties, concepts
and rules, and how they relate to each other. For dynamic packaging applications,
an ontology with the appropriate tourism concepts needs to be built for identifying
destinations, activities, weather forecasts, places, dates, and relationships. We identify
the need for two distinct types of ontologies: local ontologies and shared global
ontologies. Local ontologies define the semantics of specific tourism data source
domains, such as hotels, car rentals, and airlines. In addition, we also consider the
notion of shared global ontologies, which are common semantics shared between
all the tourism domains and tourism information systems, that is, these ontologies
model the information that resides in many separate domains.
