scope:

The present document presents a high-level description of an interface mechanism - the eWarrant Interface - for receipt of requests for measures producing real-time or stored information by an issuing authority possessing lawful authorization to initiate such a request. The eWarrant Interface is a generic, extensible interface intended to be fully compatible with all existing kinds of requests for these purposes - as well as support future ones, including local requirements and languages or character sets. The eWarrant Interface is not intended to replace existing implementation-specific mechanisms found, for example, in the Retained Data Handover Interface.

The present document describes an electronic interface. Annex B describes work flow for an eWarrant in different jurisdictions and a means for discovering related information. Annex C describes how this interface may be adapted and made interoperable for manual and legacy techniques. The present document provides a high-level description of the interface mechanism. It defines basic principles of interoperability, and provides recommendations for the types of data that are delivered. It provides a recommendation on the choice of data modelling languages, but the present document does not give a normative structure for the delivery of eWarrant messages. It is envisaged that a later Technical Specification will add the required details for a full implementation.
