Implementation of the
AS4 protocol and
the Service Metadata Pulishers (SMP)

Enhance eDelivery
interoperability to ease the adoption of the
e-Delivery Regulation

Promote the Digital Market
and the use of
electronic documents.


The eDelivery project, UP-Access, was developed and presented by LMT Group in collaboration with the Universitat de Valencia (Spain).  The aim of the project is to implement the AS4 protocol and upgrade the Service Metadata Publishers (SMP) of the 5 PEPPOL Access Points of this consortium, which are used by thousand of clients from different Member States.

The results of this action are their upgraded eDelivery solutions by substituting the AS2 by the AS4 as a mandatory procedure defined by OpenPEPPOL. The main priority is to  promote the uptake and speed up the use of the eDelivery DSI (digital service infrastructure) amongst both public and private entities established in the EU and EEA countries with the purpose of establishing access points.

The new eDelivery infrastructure resulting from the Action will fulfil the corresponding technical requirements to become qualified according to the elDAS Regulation. As a consequence, the solutions implemented will facilitate the cross-border exchange of thousands of electronic documents.

Project activities

Consortium management

UVEG will coordinate the beneficiaries, supervise the consortium and prepare project reports. Includes the Administrative and Financial Management, as well as knowledge exchange and quality assurance.

Under the task of the Administrative and Financial Management, the progress of the Action will be constantly monitored, by ensuring the respect of administrative and contractual relationships. This will also ensure the delivery of reports, deliverables and monitor project expenses. The knowledge produced throughout the entire duration of the Action regarding the Access Points implementation will be organised and stored. The overall management, storage and internal dissemination of knowledge will be the responsibility of the Project Manager, while Beneficiaries’ Contact Points will be responsible for communicating knowledge produced for the specific tasks they have been assigned.

Internal audits will be carried out to ensure the compliance of the asigned tasks. Project meetings will be held at regular intervals and in particular at the time of achieving the key milestones. In addition, the project reviews and audits to monitor the project’s progress and compliance with quality standards will be assessed.

Definition of technical requirement and consortium strategy guidance

This activity aims to define the common technical requirements to be considered by the consortium for the Access Points implementation. All beneficiaries will collaborate to identify the technical steps and requirements needed to achieve interoperability and connectivity within PEPPOL Network. The activity will result in a Consortium Implementation Strategy covering the whole project period.

The technical management of the Action will be performed by VALTIVA in collaboration with the project’s technicians of each EDI provider. The technical manager will coordinate and assist all entities on the technical bases related to their AS4 and SMP implementation and will undertake initiatives to propose technical solutions and fine-tune technical orientations whenever necessary. The technical manager will also provide support to the final crossborder intercommunication tests between the e-delivery services of participants, using the AS4 and SMP implementations.

The technical requirements analysis is leaded by UVEG, the objective of this, is to collect all the technical requirements needed to set up the Access Points according to the e-SENS and PEPPOL profiles and the Trust Service Providers (TSP) needs. It includes review the whole technical documentation associated to the meDelivery Building Block, to PEPPOL and to e-SENS regarding the AS4 and SMP implementation and the PEPPOL Access Point operating rules. It also includes reviewing the AS2 architecture of each TSP of the consortium to identify the best alternative from the technical point of view to the implementation of their new AS4 and SMP solution.

In addition, UVEG will be defining an implementation strategy to buld the AS4 and SMP, considering the technical framework of eDelivery DSI. VALTIVA will subcontrat CEF eDelivery experts to increase the quality of the quality of the technical guidelines.

AS4 and SMP Implementation

This activity aims at setting up of the AS4 and SMP for each Electronic Data Interchange (EDI) Provider of the consortium. UVEG and VALTIVA will assit the individual technical reports in order to certify each implementation.

-Implementation by Invinet: they will set up the AS4 Access Point and the SMP for the B2B Router service by Invinet. The B2B Router service is providing PEPPOL services since 2014 and we aim at migrating from our current AS2 implementation to the new agreed AS4 standard. To deploy an AS4 implementation, Invinet will choose and adapt an open source implementation of the AS4 protocol and adapt to the new solution in a production environment passing the CEF conformance tests. This includes the update of the SMP and the publication process in the Service Metadata Locator (SML) to include the AS4 details,  interoperabillity and conectivity tests performance and  quality assurance.

The AS4 implementation will be integrated into the B2B Router solution, which means that the software will have to be modified to fit into the B2B Router infrastructure. The SMP is software created by Invinel, and it will be updated to be able to handle the AS4 protocol. The migration from AS2 to AS4 has to be handled correctly and both channels must be active and available during the transition period. Besides the deployment of the AS4 access point, Invinet will modify certain components of the B2B Router service.  An expert on AS4 protocol will be hired to facilitate a smooth deployment of the new gateway, and to allow the Invinet technical team to quickly gain the knowledge required to implement and also to maintain and operate this new gateway.

-Implementation by Credemtel: Credemtel aims at migrating from the present AS2 implementation of the Credemtel AP and SMP to the AS4 protocol. The AS2 solution has been developed by a third party and licensed to Credemtel since June 2016. It has been integrated with the Credemtel Catene application platform providing a large number of document management services. These services include among others the exchange through the PEPPOL network of business documents, basically orders and despatch advises, between healthcare organisations and their suppliers. Credemtel has recently decided to internalise the relative skills starting from the internal development of the AS4 standard and its integration with the Catene Platform, as foreseen by the present project proposal. Credemtel will develop a custom AS4 implementation that might include few (small) open source components, and it will glue them together with the basic AS4-specific software components developed by Credemtel itself.

Credemtel’s AS4 implementation includes design and development of the AP and SMP software modules, integration of the new AP module with the Catene application platform, update of the SMP and publication in the SML with AS4 details  and interoperabillity and conectivity tests performance.

The internal development of the AS4 AP and SMP software modules will likely be carried out with open source technology, based on the Java language and related libraries, to meet a recent indication coming from Credem, a major Italian bank owning Credemtel. The implementation might use open source components modified to Fit into the Catene infrastructure.

-Implementation by Babelway: Babelway aims at setting up the AS4 and SMP for Babelway. The AS4 and SMP implementation will be developed internally and integrated into the Babelway solution, passing the CEF conformance test. The implementation might use some open source components modified to fit into the Babelway infrastructure. The AS4 implementation includes the installation of the software in the production environment. interoperabillity tests, quality assurance and conformance and conectiviy tests.

-Implementation by Datajust: this implementation aims at setting up of the AS4 and SMP for Datajust. The AS4 and SMP implementation will be developed internally and integrated into the Babclway solution, passing the CEF conformance test. The implementation might use some open source components modified to fit into the Datajust infrastructure. Each AS4 implementation includes the installation of the software (based on Open Source) in the production environment and interoperability, conectivity and conformance tests performance.






Project dissemination

The Action results will be widely disseminated among clients and relevant stakeholders, especially between the thousands of clients and partners of the four EDI providers of this consortium. It includes the use of social networks , mailing (emails and news sent to the clients) and the Action dissemination on the webpages and related events participated by each beneficiary.

In the one hand, Valtiva will lead the project website implementation, a dedicated website will be created at the beginning of the Action and will be used both to publish key information about the Action progress and to give and international open visibility to the Action and eDehvery.

In the other hand, UVEG will lead the definition and execution of the communication plan; This will elaborate the strategic communication plan of the Action focused on those entities and researchers involved with PEPPOL network, especially the potential new access points interested in collaborating with the consortium members. It includes the use of social networks for dissemination of the Action and of eDelivery.
