News on the Conceptual Data Model and usage examples by an Infrastructure Manager

On 11th of June, FP1 MOTIONAL Transversal Topics presented its fourth Town Hall Workshop, this time focused on providing news on the development of the Conceptual Data Model and outlining examples of usage by Trafikverket, the railway infrastructure manager in Sweden.

The Conceptual Data Model is a project- and platform-independent data model of the rail system, expressed using ontologies and making extensive references to published standards to foster interoperability, facilitate processing by machines and reduce required implementation efforts. The Conceptual Data Model is one of the four digital enablers currently under development within the Transversal Topics subgroup of the FP1 MOTIONAL project. Those enablers are intended to serve the need of the railway sector and to support the research and innovation efforts under way in the System and Innovation Pillars of Europe’s Rail.

Trafikverket provided an overview of the recurring need for an infrastructure manager to disseminate digital information to various stakeholders with large commonalities in data requirements but nevertheless a diversity of specific data requirements and expectations in data formats. Trafikverket illustrated how the combination of the Conceptual Data Model ontology and the usage of alignment ontologies enable to provide fit-for-purpose data to interested stakeholders.

An overview of the design philosophy, of the technical foundations and overall rail system coverage of the Conceptual Data Model ensued, as well as illustration of practical ongoing development aspects of the Conceptual Data Model for various activities within Europe’s Rail (infrastructure description to serve the evolving needs of ERA’s Register of Infrastructure, maintenance-related use cases within the Innovation Pillar, Rolling Stock model in collaboration with the System Pillar, …).

Finally, a short overview of the OntoRail knowledge engine, used to support the linking between ontologies and the needs of terminology harmonization within Europe’s Rail, was provided.

FP1 MOTIONAL series of Town Hall meeting will be continuing with further events planned at the end of the summer and in the following months.


Town Hall Workshop Digital Assets Engineering

Digital Asset Engineering is a work package (27) within the MOTIONAL WS2 TT project focusing on the development of digital enabler 30 (Engineering toolbox {Models,software}).

This WP aims to digitize and automate the whole planning phases to ease engineering work, reduce costs of development and testing, and reduce time to deployment. Replacing paper as common-used exchange of information in planning CCS assets by digital format is the main focus of the WP.

This edition of townhall was done to introduce the topics and the pan for the next reporting period. An update with Tool release is planned for the next town hall.


The Rail Data Space is taking shape

FP1 WP31 is on its way to develop a Rail Data Space (RDS) - a key technological enabler designed to be decentralized, open, trusted, reliable, and cybersecure. This federated data space is essential for facilitating data exchanges within the rail ecosystem, governed by a specific framework. 


Key features of the RDS: 

  • Decentralized Data Storage: Ensures data sovereignty and trust by allowing data providers to retain ownership and full traceability of their data. 
  • Secure Peer-to-Peer Communication: Enables direct interactions between participants for specific use cases, independent of a central node. 
  • Efficient Data Exchange: Achieved through the separation of metadata and actual data, enhancing exchange efficiency and data discoverability. 
  • Provider-Oriented Governance: Data providers have control over access to their data, including usage purposes, duration, and conditions. 
  • Federated and Open Access: Allows outside players to become a member of RDS through registration and identity verification as per governance framework (to be defined) and ntegrates seamlessly with other data spaces, facilitated by semantic data interoperability and conceptual data models from other WPs in FP1.

 Since July 2023, the Rail data Space has been available to all WP31 partners in "Sandbox-Environment" to support development and release of further components. 


Townhall Workshop Digital Twins

The Transversal Topic (TT) activities of the ERJU, covered by the MOTIONAL project, aim to develop an initial environment for the coherent creation, modelling, editing, and processing of data in order to facilitate the digitalisation of the rail sector. In detail, TT addresses data modelling and sharing capabilities, digital engineering processes, and digital twins.

Therefore, the second TT Townhall Meeting was dedicated to the background, concept and initial specification of the environments for the creation, assembly and simulation of modular, interoperable, composable Digital Twins. The objective was to popularize the approach and receive feedback from stakeholders within ERJU’s System and Innovation Pillar and from outside the ERJU program.
