Arelle is a project to provide an easy to use open source facility for XBRL.

The intent began to meet needs that are not commercially viable, such as to support under-development extension modules and test suite facilities, in a compact framework, and to support academic training and projects.

Features

• Support for XBRL versioning. Validation tool for versioning reports and a production tool to generate the basics of a versioning report that can be inferred by diffing two DTSes.
• Edgar and Global Filer Manual validation
• Base Specification, Dimensions, Generic linkbase validation
• Formula validation including support for extension modules
• Instance creation is supported using forms defined by the table linkbase (Eurofiling verison).
• RSS Watch facility
• Users can explore the functionality and features from an interactive GUI, command line interface, or web services, and can develop their own controller interfaces as needed.
• The Web Service API allows XBRL integration with applications, such as those in Excel, Java or Oracle.
• QuickBooks is supported by XBRL-GL.

Arelle fully integrates test cases with the object models for XBRL instances and DTSes.

This allows continual verification of tool performance as it is extended and adapted by its users.
