The institution defines a service-oriented architecture (SOA)-based model to guide the application of interoperability in the implementation of integrated social security systems.
In order to provide practical benefits to implementation, the model comprises key components such as basic registries and interoperability services.
Guideline code
ICT_03100
Mechanism
Mechanism
- The ICT unit should elaborate a service-oriented-architecture (SOA)-based model for applying interoperability in the institution, including:
- Basic registries, which are information systems including core social security data. They would be shared internally and with other institutions to promote data reusability;
- Interoperability services, to connect interoperable applications and information systems following the service-oriented architecture. They would consist of protocols (e.g. SOAP), tools (e.g. XSLT) and integration platforms (e.g. ESBs);
- External services provided by third parties participating in interoperable solutions (e.g. basic registries, financial services for contribution collection or benefit payments);
- Secure data exchange mechanisms providing a common secure environment for interoperable operations (e.g. mechanisms to authenticate operations and data);
- Aggregate services built using other basic services (e.g. combining several basic registries and external services connected through interoperability services and using appropriate secure mechanisms).
- The ICT unit, with the assistance of specialized units where applicable, should establish service level agreements covering participant services, especially external ones. This may involve formal agreements with other institutions.
- The ICT unit may take the generic model proposed in the ISSA technical documents as a reference point and refine it to develop the desired institutional model. This generic model includes specified components (defined above) and aims at reducing the complexity of developing an institutional model as well as providing a common tool for ISSA member institutions.
- The management should approve, adopt and communicate the model to all units involved.

Structure
Structure
- The ICT unit should define a model which includes the main elements required for the overall implementation of interoperable applications within the institution.
- The management should establish duties and responsibilities to specify and manage the institutional interoperability application model.
- The model for applying interoperability in the institution should be based on the institutional models and standards, such as the institutional interoperability framework, the workplan for implementing interoperability-based social programmes and the institutional technical standards.
- A generic model proposed in the ISSA technical documents may be taken as a reference point and refined to develop the desired institutional model.
