This deliverable elaborates the requirements analysis for ontology management in the DIP project. It reports on the
state of the art in ontology management, points out shortcomings of existing ontology management tools, and indicates
the development requirements for ontology management in the DIP project.
The technologies needed for ontology management comprise the ontology specification language used, devices for storage
and retrieval of ontology specifications, versioning mechanisms for supporting evolution of ontologies, and finally
devices for editing and browsing ontologies in a repository. In the course of DIP, the specific requirement is to enable
handling of large-scale, geographically dispersed ontologies, allowing concurrent access and editing, and the tracking of
changes in the specification of the ontologies, in order to provide versioning and evolution ontology facilities. The aim
of this deliverable is to depict the requirements for achieving the outcomes we have specified here, and to outline the
development directions for WP 2. Therefore, we begin by evaluating the state of the art in ontology management and show
up the shortcomings of existing solutions. Taking these shortcomings into account, we then derive the development
requirements for the ontology management environment of the DIP project, which will be the final outcome of WP 2.
