CEF eDelivery: Service Metadata Publisher (SMP) 4.0 FR Out Now

European Commission


On 26th February, the European Commission released the Service Metadata Publisher (SMP) 4.0 Final Release of the Connecting Europe Facility (CEF) eDelivery building block.

This publication follows the release of the SMP 4.0 Release Candidate on 3 January 2018.

CEF eDelivery is a network of nodes for digital communications. It is based on a distributed model where every participant becomes a node using standard transport protocols and security policies. The CEF eDelivery building block is based on the AS4 messaging protocol, open and free for all, developed by the OASIS standards development organisation. To ease its adoption in Europe, eDelivery uses the AS4 implementation guidelines defined by the Member States in the e-SENS Large Scale Pilot.

The CEF eDelivery Service Metadata Publisher (SMP) enables the participants of an eDelivery Messaging Infrastructure to dynamically discover each other's capabilities (Legal, Organisational, and Technical). For this to happen, each participant must publish its capabilities and settings in a SMP.

This release is conformant with the eDelivery SMP profile based on the OASIS Service Metadata Publishing (BDX SMP) specifications.

All necessary functionality is available to make the SMP fully operational; i.e. all necessary operations to manage Service Groups (structures that represent a set of services associated with a specific Participant identifier) and their Service Metadata (structures that represent Metadata about a specific electronic service)

The SMP 4.0 Final Release includes a range of improvements and new features and also includes several bug fixes.



The European Commission, very much welcomes the continued uptake of the AS4 message exchange protocol, underpinning a Digital Single Market in Europe.
