- What is exchanged (i.e. the knowledge)
- Space, ground operations and launchers, including all the phases of the life cycle
- Initially (short-term) focuses on the engineering data
Scope
The Space System Ontology enables the semantic interoperability between entities (Agencies and Industry) along the life cycle of a Space System. It addresses the System aspects of any Space System.
Its scope is limited to:
- Requirements Management
- Mission and operation
- The static view of the functional description
- The behavioural/dynamic view of the functional description
- Logical description
- Physical description
- Management and planning
- Support to configuration control, change management and non-conformance control
Universes of Discourse
The following Universes of Discourse (UoD) are identified as important in the short-term:
For the long term, other Universes of Discourse not related to the functional architecture, i.e. at enterprise level (including processes and functions, and also entities and relations) can be useful to provide the context for any data exchange needs. Examples of those UoDs are: risks, mechanical aspects, electrical aspects, etc.
Conceptual modelling language and tool
Object Role Modelling is selected as the best technical solution to develop the Space System Ontology.
The modelling tool for developing the Ontology is NORMA Pro.

During the conference mbse2021, a complete session (number 5) was dedicated to the Space System Ontology. In particular, two recorded videos are of interest to understand by examples the power of the language, the development approach https://youtu.be/ADX7DuNCotY and conceptualizing MBSE https://youtu.be/QrBaUFl7NwE.
