About Arelle

Arelle is an Open Source Python XBRL framework that encourages rapid design and development of XBRL applications by providing an easy to use facility for XBRL processing.  Arelle was designed to handle two challenges: the high-barrier to entry for applications developers wishing to work with XBRL content and the stringent requirements of the experienced XBRL developers who wrote the XBRL specification. It lets you build high-performing, elegant XBRL applications quickly. Arelle focuses on automating as much as possible when it comes to processing XBRL content and adhering to often complex and dense XBRL specifications.  

Developed by core XBRL specification contributors, Arelle supports XBRL extension features not widely available, including versioning, which provides a formal model of the differences between taxonomies, newly emerging validation (IFRS Global Filer Manual), table linkbase, and full implementation of XBRL formula.  A compact model-driven architecture unifies these extensions in a manner that is both a comprehensible and maintainable implementation (in terms of source code size), and easily usable by the research community.  Users can explore the functionality and features from either an interactive GUI or command line interface, and can develop their own controller interfaces as needed.  Read the overview:  Download the code:  For more information: email us at or visit
