Collaboration on iss experiment data and knowledge representation

The USOCs (User Support and Operation Centres) are a network of collaborating centres. They have been established in various EU countries with the support of national space agencies and are engaged by the European Space Agency (ESA) to conduct the operations for European scientific experiments on board the International Space Station. The USOCs Knowledge Integration and dissemination for Space Science Experimentation (ULISSE) project developed a platform and tools for improving preservation, valorisation and exploitation of experiment data. The platform integrates tools which are based on a number of formalisms to represent knowledge to be maintained and preserved. Dedicated tools for authoring metadata and knowledge about datasets have been developed to enforce a standard. Knowledge about internal data formats guided a data valorisation framework based on experiment data integration. A timeline based representation to model possible temporal evolutions of scientific payload components as well as to support the automatic definition of on-board activity schedules for performing the associated scientific experiments. Immersive visualization techniques enable intuitive exploration of knowledge about data for better understanding the context. Virtual Reality and Augmented Reality design issues for ordinary end-users were analysed. The project experience in knowledge representation and progress is addressed in support of improving preservation and valorisation of space data, representing intellectual ownership and data dissemination policies, stimulating data reuse and collaboration.
