All the documents published by an official publisher should have at least the legal value level "OfficialLegalValue". This indicates that the document was published by an organisation with the public task of making it available (e.g. a consolidated version of a EU directive published by the EU Office of Publications).
This entry is derived from the ELI ontology (European Legislation Identifier). ELI is an initiative of some national legislation publishers endorsed by EU countries and Institutions, to identify, describe and link legislation on the web, and is led by the ELI taskforce.
