The National Interoperability Framework (Royal Decree 4/2010) establishes the development of a series of Technical Interoperability Standards which must be applied by Public Administrations (P.A.s). These Standards (Interoperability Agreements) describe specific aspects needed to facilitate practical and operational aspects of interoperability. They are published in the Official Gazette and they are available at the Portal Administracion Electronica (PAE) <http://administracionelectronica.gob.es/?_nfpb=true&_pageLabel=P60215901274203521811&langPae=es>

• The Standard for eDocuments describes eDocuments as including content, eSignatures, and minimum required metadata, and the rules to exchange and copy them. The Annex contains a definition of the minimum required metadata, XML schemas for document exchange, and basic information on the signature of eDocuments. The eDocument structure allows the use of eSignatures as envisaged in the Commission Decision 2011/130/EU.

• The Standard for eFiles describes the structure of eFiles, including eDocuments, eIndexes, eSignatures, and minimum required metadata, and the specifications to send them and make them available. The Annexes contain a definition of the minimum required metadata and XML schemas for file exchange. The eFile structure allows the use of sSignatures as envisaged in the Commission Decision 2011/130/EU.

• The Standard for eDocument Digitisation describes the components of a digitised eDocument, including digital images, eSignatures, and metadata, and the rules to digitise paper documents by P.A.s in compliance with applicable formats, quality levels, technical conditions and standards.

• The Standard for eDocument Authentic Copy and Conversion Procedures establishes the rules for the production and issue of authentic eCopies and authentic paper copies of eDocuments in P.A.s, and for the format conversion of eDocuments by P.A.s.

• The Standard for eSignature and Certificate Policy sets forth the criteria for the development or incorporation of certificate-based eSignature policies by P.A.s. It describes the contents of certificate-based eSignature policies, determining the characteristics of common rules like formats, use of algorithms, or signature creation and validation for eDocuments, as well as the trust rules for eCertificates, timestamps, and long-term signatures.

• The Standard for Requirements for Connection to the Communications Network of Spanish P.A.s sets forth the conditions under which every agency in the P.A. can access the SARA Network, describes the functions and responsibilities of the agents connecting to said network, and establishes the requirements to connect to, access, and use the services provided through it.

• The Standard for Data Mediation Protocols defines the roles of the actors involved in mediated data exchanges and sets forth the conditions for mediated data exchange processes with the mediation platform of the Ministry of Finance and Public Administration, which can apply to the mediation platforms of other P.A.s. These are the conditions to be satisfied by public administrations providers and consumers in the access to base registries.

• The Standard for E-Document Management Policies describes the concepts related to e-document management policy development, identifies document management processes in e-government and sets forth the principles for the development and implementation of e-document management policies by all P.A.s.

• The Standard for Data Models establishes the conditions to design and publish the data models (semantic assets) regarding model formats, identification and documentation, use, definition and encoding, and interaction with the Semantic Interoperability Centre, publishing data models, in line with European standards and practices sponsored by JOINUP.

• The Standard for the Catalogue of standards establishes the conditions for the selection of standards, maintenance and use of standards for eGov services.
