ERA Knowledge Graph

Data Stories

This webpage contains a catalogue of SPARQL queries (together with their correspondance in natural language) that can be useful for different purposes.

Queries will be provided as independent files inside this webpage, to facilitate their maintenance and the generation of references to them from other parts of the ERA ecosystem (e.g., ontology documentation, demo sites, etc.), especially in case of ontology changes.

And some of these queries will be also grouped together in SPARQL notebooks, for convenience, providing a unified view over a specific need (e.g., parameter completeness reports per member state).

Related content

The Agency Railway Terminology Collection is a repository of Railway terms and abbreviations from EU legal texts concerning the activities carried out by ERA and relevant application guides. 

Its main aim is to sustain the development of a common understanding in the rail sector, essential to achieve the level of harmonisation required by the Railway Safety and Interoperability Directives.

The purpose of the collection is to provide support to the whole sector by:

  • offering in an unique entry point the reference valid definition of terms and abbreviations;
  • improving the multilingual translations and understanding;
  • facilitating the standardisation of railway definitions in new or revised documents , both for activities carried out internally and externally to the Agency;
  • harmonising the communication in the railway systems.

Further steps will be carried out for incorporating other terms from institutional sources and designing a multilingual web version.

Please consider that the document can be exported in Excel. The Agency is responsible only for the publication in PDF, the file is uncontrolled when printed or converted. Please note that this page is still under construction.

This is the human and machine readable Vocabulary/Ontology governed by the European Union Agency for Railways. It represents the concepts and relationships linked to the sectorial legal framework and the use cases under the Agency´s remit. Currently, this vocabulary covers the European railway infrastructure and the vehicles authorized to operate over it. It is a semantic/browsable representation of the RINF and ERATV application guides that were built by the domain experts from RINF and ERATV working parties.

This is the human and machine readable Controlled Vocabulary / Taxonomy governed by the European Union Agency for Railways. It represents the list of values per each data property linked to the sectorial legal framework and to the use cases under the Agency´s remit.

Here's a catalogue of SPARQL queries (together with their correspondence in natural language) that can be useful for different purposes. Send us your information request and we build the query for you. (Email RinfProjectTeam@era.europa.eu)
