MDR > European Legislation Identifier (ELI)

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

Pillar 1: URI Templates

Pillar 2: ELI Ontology

Documentation

The metadata elements of the ontology are documented here.

Pillar 3: Serialisation of ELI metadata elements: Integration of metadata into the legislative websites using RDFa

ELI metadata elements should be encoded following the W3C Recommendation "RDFa in XHTML: Syntax and Processing". Implementers are free to support additional serialization formats.
