Work Packages
Currently available work packages:
WP30 Conceptual Data Model and semantic dictionary evolution
The LINX4RAIL and LINX4RAIL-2 projects have initiated the definition of a Conceptual Data Model offering, a project independent railway system model with rich semantics based on a federation of UML source models. A railway semantic dictionary has been subsequently built which collects ontologies extracted from the conceptual models and allows their interlinking. The Conceptual Data Model work package will:
- process the inputs received from WP26 on requirements, constraints and timelines for extension and evolution of CDM
- based on extension needs, identify the most appropriate means (new source models, extension of an existing source, …) to extend the coverage by the CDM of the railway system favouring a maintenance of a cohesive conceptual model backed by clear and strong semantics (facilitating machine-processability and interoperable usage of the underlying data),
- enforce the technical aspects of the CDM governance process, in liaison with the System Pillar
- ensure the liaison with representatives of the source models considered in the federation of models
