Specification - Recommendations
A Recommended Specification is a work that represents consensus within the XBRL International community and has its stamp of approval. The International Steering Committee considers that the ideas or technology specified by a Recommendation are appropriate for widespread deployment to promote the mission of XBRL International. The current Base Specification is 2.1 and all users are strongly encouraged to use this latest version. Versions earlier than 2.1 are no longer supported or maintained by XBRL International: no errata corrections will be issued for them.
Inline XBRL 1.1 - November 18, 2013
Version 1.1 of the Specification for Inline XBRL contains three new features:
- the addition of an extended mechanism, ix:continuation, for splitting text content within a document;
- the addition of nesting of ix:nonFraction and ix:fraction elements; and
- the addition of support for fact-explanatoryFact links, by replacing the existing mechanism for structuring footnotes with a one based on a new element, ix:relationship.
Minor changes have been made to the grammar and layout of the specification in order to improve consistency and accuracy, but in other aspects, the specification has remained unchanged semantically from version 1.0
There is an accompanying conformance suite which can be downloaded here.
Variables 1.0 - June 22, 2009 with errata corrections to November 18, 2013
This specification is an extension to the XBRL Specification. It defines syntax for structures that support the extraction and usage of information from an XBRL instance and its supporting discoverable taxonomy set. The proposed edits are described in Appendix E
This specification provides building blocks for other extension specifications including for XBRL formulae and for assertions about the expected content of XBRL instances.
The errata corrections to the original recommendation can be found in the document in Appendix F.
For reference, previous editions can be found on the Old Editions page.
Units Registry - Strucutre 1.0 - November 18, 2013
This document describes the structure of the XBRL International Units Registry. The Units Registry is an online listing of units that have been identified as potentially having wide utility. The Registry contains structured information about their purpose, usage and any intended impact on XBRL instance validation.

Versioning Specification - Base, Concept Use, Concept Details, and Dimensions - February 27, 2013
The Versioning Specification is a modular specification, allowing users to implement those parts of the specification that are relevant for a particular use case.
The 15th August 2012 CR release of the specification changed the name and content of some modules in order to add clarity, and to better reflect the requirements of common use cases descriptions of these changes are below:
- Concept Use was previously known as Concept Basic
- Concept Details was previously known as Concept Extended
- Dimensions was previously part of the Instance Aspects module. The remaining scope covered by the Instance Aspects module may be released in separate modules in the future
The text of these specifications may be found at the following links
- Versioning - Base (HTML)
- Versioning - Concept Use (HTML)
- Versioning - Concept Details (HTML)
- Versioning - Dimensions (HTML)
Additional explanatory information about the versioning specifications is contained in a series of Working Group Notes that are available on the Working Group Notes page of this website.
XBRL 2.1 - December 31, 2003 with Errata Corrections to February 20, 2013
A new edition of the 2.1 Specification with errata corrections was issued on February 20, 2013. This edition incorporates no new errata, and is semantically equivalent to the January 25, 2012 edition, but the HTML version is now normative. For reference, previous editions can be found on the Old Editions page.
The schemas for this edition can be found at:
XBRL 2.1 Conformance Suite (Candidate Recommendation 5) - January 24, 2012
The XBRL 2.1 Conformance Suite provides more than 200 tests to verify that applications process XBRL 2.1 documents correctly. The normative version of the suite is available as a downloadable zip file. Users should note that this is a non-normative location and the latest versions of tests are NOT guaranteed always to be available. Users are encouraged to download the zip file for routine testing. In the event of any conflict between the contents the downloadable zip and the files at the location above, users should treat the contents of the downloadable zip file as the correct version.
For developers who prefer to work in a "Subversion" environment, the conformance suite is also provided (non-normatively) in a public "read-only" Subversion repository located at http://publicsvn.xbrl.org/svn/public/base-specification-conformance/2012-01-24/
Dimensions 1.0 - September 18, 2006 with errata corrections to January 25, 2012
A new edition of the Dimensions 1.0 Specification with errata corrections was issued on January 25, 2012. This should be used in preference to old editions, but for reference the latter can be found on the Old Editions page.
The Dimensions 1.0 Specification is a modular, optional extension to the XBRL 2.1 Specification which allows XBRL taxonomy authors to define and restrict dimensional information for instance authors to use in the segment and scenario elements of the context element of XBRL instance documents. Its architecture is such that any XBRL artefacts (instances and their Discoverable Taxonomy Sets) that conform to this specification also conform to the XBRL 2.1 Specification and may be processed without error by any processor that is capable of correctly processing XBRL artefacts, even if those processors are unaware of this modular extension

Transformation Registry Version 2 - October 24, 2011, Document internal date July 31, 2011
This Transformation Rules Registry is published by XBRL International Inc. in support of the specifications for Inline XBRL. The Transformation Rules defined here are used to allow text strings in Inline XBRL Documents to be converted into the data types used within XBRL instance documents.
New versions of this Transformation Rules Registry will be published, from time to time, by XBRL International Inc. Each version is identified by its XML namespace.
This version provides new, more generalised, transforms that, amongst other things, address the need for dates to be represented in many different languages, including a number of Asian languages.
A .zip file contining the specificiation as well as a conformance suite and a set of reference transforms may be downloaded from here (48 MB)
For developers who prefer to work in a "Subversion" environment, the conformance suite and reference transforms are also provided (non-normatively) in a public "read-only" Subversion repository located at http://publicsvn.xbrl.org/svn/public/inline-xbrl-conformance/Transformat...
