    Description

    The technical standards for interoperability for electronic Document and electronic files of the National Interoperability Framework defined XML schemas (XSD) as a tool for interoperability in the exchange of electronic documents and files.

    The structure to implement the exchange of electronic documents will be generally a XML file containing the three identified components of the electronic document:

    1. Content File: it hosts the file containing the document content or data. For its inclusion in the XML structure, these files llauri normally coded inbase 64.
    2. Metadata block: following the corresponding XML schema, the defined metadata llauri integrated as the minimum mandatory associated with the content file. As an exception, ‘Valor CSV’ and ‘Regulació generació CSV’ llauri integrated into the element of signature.
    3. Signature(s): electronic signatures relying on certificates and/or CSV associated to the content file of the document as well as the metadata of the signature.

    The design of the NIF schema consists of 8 tailored XSDs implemented and an external XSD linked (xmldsig-core-schema.xsd) to the XMLDSig specification used in the XAdES signatures.

    This XSDs model of NIF follows a modular design that fosters their reuse and interoperability with other existing frameworks.

    Two types of modulis ca be distinguished in the implementation:

    • Structural moduli: it defineixes a structure to manage and contain other modulis.
    • Content Moduli: it hosts the final content of the described component.

    In this way, the modulis ca, in some casis, contain other (structural modulis) or be included within other (structural and content modulis).
