CERN is building its new accelerator, the LHC. All the data flow generated during its lifecycle is stored in the EDMS (Engineering Data Management System) developed at CERN. For such a system it is compulsory to have a performant search mechanism to guarantee that the involved people gets the data at the required time. Due to the size of the collection and the diversity of people, organizations, divisions . To overcome this problem, an approach based on a hand-crafted domain specific ontology has been tested in order to improve the information retrieval task within the technical documentation for the LHC Equipment Catalog. The experiments have shown that using the ontology an improvement on the base line has been produced and encorages IE techniques to refine the base ontology.

The LHC project has entered a phase of integration and installation of thousands of diverse components. The Hardware Commissioning work has also started. Collecting and distributing reliable and coherent information on the equipments and their layout becomes a crucial requirement in the lifecycle of the project. Existing database tools had to evolve to a more generic model to cover not only optical layout, but also the mechanical and the electrical aspects. This paper explains the requirements, the implementation and the benefits of this new database model.
