Taxonomies are dictionaries used by XBRL. They define the specific tags for individual items of data (such as “net profit”). Different taxonomies will be required for different financial reporting purposes. Different XBRL jurisdictions may have their own financial reporting taxonomies to reflect their local accounting regulations. Many different organisations, including regulators, specific industries or even companies, may require taxonomies to cover their own business reporting needs.
