Inline XBRL provides a mechanism for taking financial and business information formatted in HTML, the universal language for web browsers, and adding to it hidden metadata which can be used to construct a machine-readable copy of the same information. That extracted, machine-readable, information is fully compliant with the [XBRL 2.1] standard and can be used by regulators and other consumers of financial information.
