Cooperation between the public administrations is essential to provide services to citizens and guarantee their rights. Such cooperation requires such conditions that enable its fluidity, requires interoperability. Interoperability facilitates the realization of principles and rights of citizens; cooperation in the development and delivery of public services; as well as a more effective and efficient deployment and in the provision of services.

Article 3 “ general principles ’ Law 40/2015, of 1 october, from The Legal Regime of the public Sector (Opens in new window) includes interoperability between the principles of action of the public administrations, so that these will relate to one another through electronic means to ensure interoperability and safety systems and solutions adopted by each of them, the protection of personal data, and facilitate the provision of services to stakeholders.

Article 156 of the law 40/2015 reflects the national Interoperability (ENI) that “ it includes the set of criteria and recommendations on security, maintenance and standardization of information, formats and applications that should be taken into account by public authorities for decision-making technological guarantee interoperability ”.

The ENI was established earlier in article 42 of law 11/2007 and is embodied in the Royal Decree 4/2010, of 8 january, which regulates the national Interoperability (Opens in new window) in the area of E-government.

The technical standards for interoperability specific details to facilitate the most practical and operational interoperability between the public and with the citizen. They are accompanied by implementation guides and other supplementary documents.

The ENI is the result of a coordinated by the ministry of economic and Digital Transformation. All public administrations involved in drafting the ENI through Collegial bodies with competence in the area of digital administration; and was also organized with the opinion of the industry associations of information and communication technologies.

In the development of the ENI and their technical standards were taken into account the recommendations from the european union, particularly of the European Interoperability framework (Opens in new window) available to date; therefore, the ENI is located in the context of european policies, actions, documents and services relating to interoperability; it also contemplates the concept of the liaison with the various instruments equivalent the scope of the european union, are communications networks, basic components (building blocks), or services for cooperation in interoperability or reuse.


The national Interoperability pursues the following objectives:

  • To understand the criteria and recommendations to be taken into account by public authorities for decision-making technological guarantee interoperability and to avoid discrimination to citizens by reason of their choice. And thus contribute to creating the conditions necessary for interoperability in the use of electronic means to allow citizens to governments and the exercise of rights and the fulfilment of duties through such means.
  • Provide the common elements to guide the actions of public administrations on interoperability, to facilitate the interaction of public administrations, as well as the communication of the requirements of interoperability to industry.
  • To facilitate the implementation of security policies by contributing to a greater degree of technical soundness and economies of scale.

Interoperability is conceived, safety, in a comprehensive manner, so that there is no specific sections conjunctural or treatments, because the weakness of a system is determined by its most fragile and often this point is coordination between appropriate measures individually but poorly assembled.

Elements of the national Interoperability

The main elements of the ENI are:

  • The basic principles of interoperability : interoperability as integral quality present from the design of systems and services throughout their life cycle; the multidimensional nature of interoperability; and the approach of multilateral solutions. (Arts. 4 - 7)
  • Organizational interoperability - includes aspects relating to the publication of services through the communications network of public administrations ( SARA "href =" https :// "> network SARA ), with the conditions attached; the use of nodes of interoperability; and keeping an inventory of administrative information (Arts. 8 - 9).
  • The semantic interoperability: through the publication and implementation of the data model, horizontal and sectoral, as well as those relating to the infrastructure, services and common tools. (Art.10)
  • Technical interoperability: through the use of standards in the conditions laid down in the regulations to ensure the independence in the election, adaptability to progress and non-discrimination of citizens by reason of their choice. (item 11)
  • Infrastructures and common services dynamization, elements, simplification and spread of interoperability, while facilitating multilateral engagement. (Art. 12)
  • The use, preferably, of the communications network of public administrations in spain to communicate with each other and their networks that connect and nodes of interoperability, applying Plan addressing the administration . The SARA "href =" https :// "> network SARA given the above-mentioned Communications network. (Arts. 13 - 15)
  • Reuse: includes conditions of dismissal of applications, documentation and other objects of information by public administrations to make available to other authorities and of citizens; link between the directories of reusable applications and by public administrations of solutions available for free reuse; as well as publication of the code of applications. (Arts. 16 - 17)
  • The interoperability of electronic signatures and certificates: the policy of electronic signatures and certificates of the General state administration as a tool that can be used as a reference for other AA.PP.; aspects relating to the validation of certificates and signatures, the lists of confidence, the user applications, certification services providers and validation of certificates and electronic signature. (Arts. 18 - 20)
  • The revival and preservation of the electronic record, as a manifestation of interoperability over time, and that has a unique to the electronic document. (Arts. 21-24)
  • Creates the technical standards for interoperability and instruments to interoperability. (Additional provision first)

Ámbito of implementation

The scope of the national security is established by article 2 of the law 39/2015 and 40/2015 on the subjective scope and what is said on the public sector institutional.

Alignment with national Interoperability

To the adequacy of ENI is of interest to the Guide of implementation of audit ENI (Opens in new window) that is intended to facilitate to carry out an assessment of the implementation of the measures of interoperability, pointing out a list of measures on national Interoperability. Such controls are structured into three categories following the model of the NHIS:

  • Organizational framework , referred to those controls demanding horizontal measures, such as the legal aspects of policies for action or certain decisions, often referred to the governance of interoperability.
  • Operational framework , referred to those controls whose implementation requires the adoption of practices, procedures and measures in line with the administration of interoperability as a whole, including the design, implementation and the design and operation of interoperable systems.
  • Technical measures , que suponen requisitos concretos que permiten garantizar la interoperabilidad, incluyendo formatos, vocabularios o protocolos.
