    Cooperation between the AA.PP. is essential to provide services to citizens and guarantee their right to interact with them electronically. Such cooperation requires conditions that allow the same can be carried out smoothly for which it is necessary that interoperability.

    The national Schema Interoperability stipulated in article 156, paragraph 1, of the law 40 / 2015, 1 October, of Legal Regime of the public Sector, which replaces paragraph 1 of Article 42 of Law 11 / 2007, of 22 June, electronic access of citizens to public services.

    The ENI has been formulated by the light of the state of the art and the main referents on interoperability from the European Union, national and international standardization, like in other countries, etc. The ENI is aligned with the European Strategy of interoperability (Opens in new window) and European Framework of interoperability (Opens in new window) .

    • Make a common language to facilitate interaction of the AA.PP., as well as the communication of the requirements of interoperability industry.

    Interoperability is conceived from a comprehensive perspective, so that there can be no action punctual or cyclical treatments, due to the weakness of a system is determined by its point more fragile and often this point is the coordination between individual measures appropriate but poorly assembled.

    Elements of the National Schema interoperability

    The ENI introduces the following main elements:

    • The specific principles of interoperability: interoperability as integral quality present from conception of services and systems and throughout their life cycle; the multidimensional nature of interoperability; and the approach of multilateral solutions.
    • Technical interoperability: through the use of standards (Opens in new window) under the conditions laid down in the regulations to ensure the independence in the election, adaptability to progress and non-discrimination of people because of their choice.

SARA network (Opens in new window) provides the aforementioned Communications network.
    • The reuse (Opens in new window) : includes conditions of licensing of applications, the documentation associated and other objects of information that the AA.PP. made available to other administrations and citizens; Technology transfer centre (Opens in new window) link between applications directories reusable and consultation by the AA.PP. of solutions available for free reuse; as well as publication of the code of the applications.
