Turning Transport Data to Comply with EU Standards while Enabling a Multimodal Transport Knowledge Graph
This addresses data compliance and interoperability challenges for transport stakeholders in the EU, though it is incremental as it applies existing technologies to a specific domain.
The paper tackled the problem of converting transport data from multiple stakeholders into formats compliant with complex EU standards like NeTEx and SIRI, using Semantic Web technologies to enable a multimodal transport Knowledge Graph for intelligent querying and added-value services.
Complying with the EU Regulation on multimodal transportation services requires sharing data on the National Access Points in one of the standards (e.g., NeTEx and SIRI) indicated by the European Commission. These standards are complex and of limited practical adoption. This means that datasets are natively expressed in other formats and require a data translation process for full compliance. This paper describes the solution to turn the authoritative data of three different transport stakeholders from Italy and Spain into a format compliant with EU standards by means of Semantic Web technologies. Our solution addresses the challenge and also contributes to build a multi-modal transport Knowledge Graph of interlinked and interoperable information that enables intelligent querying and exploration, as well as facilitates the design of added-value services.
