XBRL is based on the definitions of taxonomy and instance. Taxonomy is intended to mean a file that contains a list of information categories that can be used by an instance - we can basically define it as a “dictionary”. On the other hand, an XBRL instance document is an XML document that contains the information defined in the taxonomy.
The user can select from four types available in the reference taxonomy: financial statements for the year, consolidated financial statements, financial statements in abbreviated form and financial statements in abbreviated, simplified form.
Possible future revisions of the reference taxonomies will be immediately available thanks to a specific Internet-based update function included in the module.
