Electronic Document

Technical standards of interoperability Electronic document and Electronic file national schema Interoperability define XML schemes (XSD) as a tool for interoperability in the exchange of electronic documents and files.

La estructura a aplicar para el intercambio de documentos electrónicos será de forma general un fichero XML que incluirá los tres componentes del documento electrónico identificados, esto es:

1. Fichero de contenido: que alberga el fichero que contiene los datos o contenido del documento. Para su inclusión en la estructura XML, estos ficheros se codifican normalmente en base64 .
2. Block of metadata: in which around the outline XML, integrates the metadata defined as mandatory minimum associated with the previous content file, except ‘ CSV Value, ’ and ‘ Regulation CSV generation ’ which will be integrated into the element of signature.
3. Signing/s: whether electronic signatures based on certificates and/or CSV file associated with the contents of the document, as well as the metadata of the signature.

Complete design of the ENI schema consists of 8 XSDs implemented to measure and an external XSD linked (xmldsig-core-schema.xsd) of the specification XMLDSig that is used in the signatures of type XAdES.

This model of the ENI XSDs remains a modular design that fosters reuse and interoperability with other existing schemes.

In the implementation, can distinguish two types of modules:

• Structural module: which defines a structure to manage and contain other modules.
• Módulo de contenido: que alberga el contenido final del componente descrito.

In this way, the modules can in some cases contain other (structural modules) or be included within other (modules of content and structural).

El listado completo de los XSDs diseñados para atender a las necesidades del ENI se incluye en la siguiente tabla:
