DE4A common specifications and components it2

This section provides an overview of the common components and specifications required for the evidence exchanges.

Common specifications

Usage of third-party specifications and components

It comprises a list of elements and a description of the third party libraries and components that have allowed to build the DE4A components faster and allowing expandability, therefore increasing the stability and robustness of the system.

Common behaviour and interactions between components

Introduction to the chapter, highlighting the fact that the description of the behaviour is done through communication diagrams. Links to the five communication diagrams and the data dictionary.

Summary of software interfaces

REST APIs interfaces reference for most of the components involved in the message exchanging.

DE4A Logs and error messages

Definition and reference of error coding and logs handling. Includes standardised log and error messages within the DE4A project to provide a good understanding of the different components regarding their points of failure and the different states in which each system is placed.

Common Components

DE4A Connector

The main component of the DE4A communication infrastructure for processing request and response messages from DP/DCs. The DE4A connector handles the message exchange process and obtains information from different nodes like IDK or SMP for this purpose. It implements the AS4 Gateway functionality, so it can undertake either Requestor or Transferor roles.

DE4A Connector installation and configuration guide

Step by step guide to successful configure an instance of the DE4A Connector. Find in this section all aspects related to the different configuration scenarios and keypoints of the system.

Testing infrastructure

DE4A Playground

It comprises a set of components and utilities provided for pilots and partners for testing purposes. In addition it can be used to replace some components that might not yet be available or that they need to be tested in a "real" environment.
