CoreFiling is a privately-held company registered in England. We are one of Europe's leading XML vendors, with a substantial history in the successful design, publication and validation of XML and XBRL. Our success is based on tools and services created with an uncompromising commitment to engineering excellence.

The company is an active member of the XBRL Consortium which promotes the adoption of the standard and oversees its development. Our CEO is the immediate past Chairman of the XBRL Standards Board and sits on the International Steering Committee. Our staff also play leading roles in the key Rendering, Versioning and Base Specification & Maintenance working groups.

As a supplier of XBRL tools, we have been involved in some of the world's largest taxonomy development projects.

Originally developed for use at a large Wall Street financial services organisation, CoreFiling's SpiderMonkey taxonomy editor is today used within both the US GAAP taxonomy and the Netherlands Taxonomy Project.

The Review Platform being used by XBRL-US to display the US GAAP taxonomies is also powered by the Yeti.
