This section provides a variety of information to help in the use and understanding of XBRL.

A basic explanation of XBRL can be found on the How XBRL Works page in the What is XBRL section. The Education and Training section provides further, more detailed explanation.

Specifications provide the fundamental technical definition of how XBRL works. It is recommended that new implementations of XBRL should follow the latest version of the main Specification, version 2.1. The separate Specifications section gives access to all specifications published by XBRL International as well as requirements for new specification modules.

Taxonomies are the dictionaries used by XBRL. The Taxonomies section lists all taxonomies officially recognised by XBRL International and provides further explanation on their role. The Taxonomy Guidance page within this Support section provides rules on how taxonomies should be created. The Instances and Reports page gives guidance on how financial reports should be put into XBRL. The XBRL files which represent the data in financial reports are known as Instance Documents. Examples of data published in XBRL and information on current XBRL projects can be found in the separate Showcase section.

The Tools page lists some software tools supplied by XBRL members to support implementation and use of XBRL.

The Link Role Registry provides a set of standard technical features which may be used in XBRL taxonomies and instances.

The XBRL Product Roadmap sets out XBRL International's current plans for the development and release of technical documents and production of training materials.

XBRL International also publishes a range of Conformance Suites to help developers ensure that their software complies with XBRL specifications and standards. These can be found via the section of the web site to which they are relevant (for example the Specification Conformance Suite is in the Specification section) and they are also listed in the Conformance Suites page.

General or technical issues concerning XBRL can also be raised or discussed on our public Discussion Groups. Click here for more details.
