Taxonomies are the reporting-area specific hierarchical dictionaries used by the XBRL community. They define the specific tags that are used for individual items of data (such as “net profit”), their attributes and their interrelationships. Different taxonomies will be required for different business reporting purposes. Some national jurisdictions may need their own reporting taxonomies to reflect local accounting and other reporting regulations. Many different organizations, including regulators, specific industries or even companies, may require taxonomies or taxonomy extensions to cover their own specific business reporting needs.
