Project Tavi 1.0

Project Tavi is an initiative to create the next generation of the XBRL Standard. The new specification is built around a simples syntax-independent model for both taxonomies and reports, and an accompanying JSON syntax.

Project Tavi is a working title. The project was previously referred to as "OIM Taxonomy", but has been renamed as this did not accurately describe its scope or content.
