XBRL (Extensible Business Reporting Language) is an XML-based computer language for the electronic transmission of business and financial data. The goal of XBRL is to standardize the automation of business intelligence (BI).
XBRL is an open standard which is overseen by a not-for-profit organization called XBRL International. XBRL uses tags to describe and identify each item of data in an electronic document. The tags allow computer programs to sort through data and analyze relationships quickly and generate output in various formats. Because the tags are standardized, analysis can be conducted across multiple documents from multiple sources, even if the text in the documents is written in different languages.
Open Source XBRL
Arelle is a project to provide the XBRL community with an easy to use open source platform for XBRL. It supports XBRL and its extension features in an extensible manner. It does this in a compact yet robust framework that can be used as a desktop application and can be integrated with other applications and languages utilizing its web service.
XBRL Taxonomy Editor

The XMLSpy XBRL taxonomy editor uses the same editing paradigm as the popular graphical XMLSpy XML Schema editor, providing a graphical view of XBRL taxonomies and intelligent taxonomy editing features. By organizing different components on easy-to-filter tabs and providing informative icons, mouseover messages, detail windows, and context-sensitive entry helpers, the XMLSpy XBRL taxonomy editor makes it easy to both view and understand existing taxonomies, and create new ones by way of extending industry-standard taxonomies. It even includes the handy XBRL Taxonomy Wizard to give you a head start when extending or creating a new XBRL taxonomy.
