Domain Design Application (DDA), the modelling platform used at ESA-CDF by domain engineers to execute design activities. 2. The OCDS communication layer based on a web services enabled service oriented architecture (SOA).

The presentation begins with a brief overview of the Concurrent Design Facility (CDF) concept as it is today at ESTEC and the benefits of the concurrent design approach. The OCDS project is then introduced with its goals to share CDF data in a central database and in a standard data representation (particularly ISO 10303). In the OCDS solution clients and server communicate via web services. These enhancements will allow the CDF to integrate remotely located actors & design centres that use heterogeneous applications and data representations for various types of space mission design concepts.

The application areas range from information filtering and document retrieval to multimedia retrieval and data sharing in large scale distributed database systems. The WordNet derived knowledge base makes semantic knowledge available which can be used in overcoming many problems associated with the richness of natural language. A semantic similarity measure is also proposed which can be used as an alternative to pattern matching in the comparison process.
