D2.1 Generic, federated OOP architecture (1st version)
This deliverable presents the first version of a generic federated OOP architecture, supporting interconnection and interoperability of national registries at the EU level. The architecture is in line with existing EU frameworks (EIRA, EIF), takes into account the e-SENS European Interoperability Reference Architecture and is based on the CEF DSIs and the Building Blocks consolidated by the e-SENS project. The first version focuses on interoperability at business and information level, to be
... ion level, to be extended iteratively in the future versions. The deliverable includes, among others, the requirements, the initial building blocks, and the interface specifications of the generic federated architecture. The overall logic of the deliverable emerges from the principle of reusing existing frameworks and building blocks provided by CEF, e-SENS, and other initiatives. As the first step, an initial inventory of existing e- Government Building Blocks is proposed. Then the principles of selection of building blocks for OOP applications and several types of high-level view of the architecture are provided. Finally, an analysis of selected building blocks with respect to their relevance, applicability, sustainability, need for further development, and external interfaces is presented. The next steps are to develop the architecture in more detail and to elaborate other tasks of TOOP T2.1 – development of a framework for specific OOP architectures and providing deployment profiles for building blocks.
