Canonical Evidence
Canonical Evidence is the canonical form of a domestic evidence according to a common data structure and format. DE4A has defined a canonical form for each of the evidence types required by the procedures involved in the cross-border evidence exchange. Since canonical evidence is not lawfully issued evidence, issuing authorities should provide both domestic and canonical evidence and they are responsible for the accuracy of the matching between canonical and domestic evidences. In this way, canonical evidence is aimed at the automated processing of cross-border and domestic evidence for legal audits at a regular basis or at the request of interested parties. This approach follows the logic behind the multilingual standard forms set by the Regulation 2016/1191 on Public documents.
The canonical form for each evidence type that has been identified is called canonical evidence type and these types are essential for the semantic interoperability of cross-border evidence, since they provide agreements on concepts, meanings, languages and ways to represent the information.

Canonical evidence types are implemented according to common data models that are defined from domain-specific ontologies, which reuse existing standard agnostic and specific vocabularies, code lists and data models. Canonical evidence types and common data models are defined according to agreements reached by involved authorities; in the case of the DE4A project, the agreements have been reached by the participants in the DE4A pilot use cases.
The terms of each canonical evidence type are described in detail in the Multilingual Ontology Repository in order to allow competent authorities to perform the necessary tasks for mapping their domestic evidence with the corresponding canonical form with an accuracy matching between them.
