Ontologies - EU Vocabularies


An ontology – in the context of computer and information sciences – can be defined as a formal specification designed to delimit and group instances/concepts (facts, events, entities, elements, etc.) based on their common class (types, properties, interrelationships, etc.), and thus formalising a full or a subset of a domain.

CAMSS Assessments
CAMSS Assessment is a solution which corresponds to the output of an assessment of a standard or technical specification using the CAMSS Tools. Each assessment produced is considered a CAMSS Assessment once it is approved by the CAMSS Team. Any approved assessment is published by the CAMSS Team and publicly available within the Assessment Library.
Common Data Model

CDM is the Common (Meta-)Data Model of the resources published by the Publications Office of the European Union

It is an ontology based on the FRBR model, described by using RDF(S)/OWL technologies, able to represent the relationships between the resource types managed by the Publications Office and their views according to the FRBR model in terms of Work, Expression, Manifestation and Item.

In CDM all types of documents created/issued by the European institutions, the activities (mainly legislation) by which the documents are created and the relations between the objects are described formally.

The documentation for the CDM version currently active in the Common Repository (Cellar) can be obtained by dereferencing the ontology URI http://publications.europa.eu/ontology/cdm

ECCF Core Ontology
The European Commission Conceptual Framework (ECCF) is a knowledge model for high-level enterprise descriptions of EU institutions and any other public service organization. It is intended as a core ontology to be extended with classes and properties specific for each policy domain and service. ECCF provides a formal representation of the following story describing Public Service organisations (PSO): A PSO provides Services via Actors, having Motivation and Capabilities, using Policy Instruments and Assets.

The European Legislation Identifier rests on three pillars:

  1. Identification of legislation: URI templates at the European, national and regional levels based on a defined set of components
  2. Properties describing each legislative act: Definition of a set of metadata and its expression in a formal ontology
  3. Serialisation of ELI metadata elements: Integration of metadata into the legislative websites using RDFa
ERA vocabulary

ERA vocabulary is an ontology defined by the European Union Agency for Railways (ERA) to describe the concepts and relationships related to the European railway infrastructure and the vehicles authorized to operate over it. The infrastructure portion contains the Implementation layer that represents the railway network as a number of operational points (OPs) connected with sections of line (SoLs), describing the following structural subsystems of the Union rail system: the infrastructure subsystem, the energy subsystem, the trackside control-command and signalling subsystem. It also contains the Topological layer where the network topological concepts are defined. The Railway Vehicle types portion contains the route compatibility check-related technical characteristics of vehicle types.

The author of ERA vocabulary is ERA and it is published by the Publications Office of the European Union on the EU Vocabularies website.

EU Budget Vocabulary

The EU Budget Vocabulary and its RDF serialisation are designed to facilitate the exchange, increase the understandability and foster the reusability of budgetary information published by the EU. The Vocabulary aims to increase government transparency by improving the availability, usability and understandability of the EU Budget.

EUropean Research Information Ontology

EURIO (EUropean Research Information Ontology) conceptualises, formally encodes and makes available in an open, structured and machine-readable format data about resarch projects funded by the EU's framework programmes for research and innovation.

Europass Learning Model

The Europass Learning Model can be used to capture the results of any non-formal and formal learning across Europe, as well as the validation of non-formal and informal learning. It is designed to provide a single format to describe certificates of attendance, examination results, degrees and diplomas, diploma supplements, professional certifications, employer recommendations and any other kind of claims that are related to learning.

eProcurement Ontology
The objective of the eProcurement Ontology (ePO) is to put forth a commonly agreed OWL ontology that will conceptualise, formally encode and make available in an open, structured and machine-readable format data about public procurement, covering it from end to end, i.e. from notification, through tendering to awarding, ordering, invoicing and payment. It aims at unifying existing practices, thus facilitating seamless exchange, access and reuse of data. eProcurement Ontology is maintained by the Publications Office of the European Union on the EU Vocabularies website.
