The IASCF released the 2011 version of the IFRS XBRL Taxonomy. You can get to the taxonomy information here.
Also, if you are not aware of it, I want to point out the "Global Filing Manual". The global filing manual is described as follows per the web site:
The Global Filing Manual contains a set of rules which provide guidance on the preparation, filing and validation of XBRL filings created using the IFRS Taxonomy, the EDINET (Electronic Disclosure for Investors’ NETwork) Taxonomy or the U.S. GAAP Taxonomy. It is the first set of aligned XBRL (eXtensible Business Reporting Language) filing rules for global use and has been published by the Interoperable Taxonomy Architecture (ITA) project.
