Introduction to this section

This section contains articles relating to using taxonomies that require extensions, such as ESMA's ESEF iXBRL mandate.  The articles in this section must be read in conjunction with the articles in the XBRL Tagging section which deals with the principles of XBRL tagging a document. 

We recommend reading the XBRL Tagging section first as knowledge of the principles will be assumed in these articles.

ESMA's ESEF iXBRL mandate is an example of a mandate that requires taxonomy extensions.  The process of converting a document into ESEF format consists of the following main steps:

1. Preparing the source annual financial statements (AFS) for conversion.
2. Importing the prepared AFS into Report Authority for conversion.
3. Applying the mandatory tags.
4. Individually tagging the primary statements.
5. Block tagging the notes to the financial statements (only required for year ends December 2022 or later).
6. Validating the document and clearing any blocking errors.
7. Exporting to ESEF format.

Date and number formatting

It is critical before you start that Report Authority is configured with the appropriate regional settings.  This will ensure that dates and numbers can be tagged with ease regardless of the formats adopted in the document to be tagged, e.g. "1,234,567.89, "1 234 567,89", "1.234.567,89" etc.  Please refer to this article for more information.
