The first part the business reporting chain is taxonomy development. A taxonomy is a set of rules and terminology that ensures that reporting is consistent and unambiguous. This is typically done alongside (if not by) the business, government, or regulatory body. As regulations or business needs evolve, taxonomies are developed, reviewed, released and maintained by the owner.   

Often business owners, accountants, auditors need to provide additional information specific to their report in the form of foot notes etc. Hence taxonomies are often extended with this information.
