Guideline 57. Institutional architecture

Submitted by Anonymous (not verified) on Tue, 07/10/2018 - 09:46

The institution defines an institutional architecture specifying the mechanisms to perform an effective and secure interaction between the institution’s systems and those at the national and international levels.

Guideline code

ICT_07600

Mechanism

The ICT unit should define an institutional architecture to perform interaction with other institutions, enabling international data exchanges in an efficient and secure way.
The institutional architecture should include an Institutional Exchange System (IES) that implements mechanisms for managing requests and responses interacting with the NES (National Exchange System) and with the international CRS (Common Reference Service). The main functions of the IES include:

Providing an effective and secure connection between the institution’s ICT systems, the NES and the CRS;
Providing transaction flow management capabilities that enable the institution to accept, suspend or reject individual case transactions;
Generating requests to other institutions participating in the agreement;
Validating incoming requests prior to their being processed by the institution’s information systems;
Generating response messages to requests;
Validating outgoing messages prior to sending them to the NES and CRS;
Providing timely information on the status of each request sent by the institution, as well as mechanisms for maintaining service-level agreements (SLAs) accordingly.

The IES may be implemented based on the paradigm of asynchrony message processing:

The implementation of asynchrony message processing may be based on message queues using an appropriate middleware system in order to manage the SLA message control parameters;
The IES may include a data transformation component to adapt the requests received for its own institution’s information system schemes. This component may be implemented using standard technologies such as the XSLT language transforming XML data packages;
This approach may enable the implementation of a case-by-case processing approach for requests and responses.

Structure

The management should commission the ICT unit to define and implement an institutional architecture to manage requests and responses exchanged with other institutions participating in the agreement.
The institutional architecture should be in conformance with the institutional principles defined to manage the main operations and resources involved in the agreement, as recommended in Guideline 3.
The institutional architecture should comply with institutional security and data protection policies and measures.
The institutional architecture should be based on the institutional architectures as well as the recommendations of the current set of Guidelines, particularly Section A.2, ICT Management, and Part B, Key Technologies.
