The first draft of its Abstract Model  was released at the 23rd XBRL International Conference in Montreal, Canada. The abstract model has been developed by XII’s Abstract Modelling Task Force (AMTF) as a means of establishing a common framework for communicating and understanding the XBRL technology. The abstract model provides a conceptual framework for understanding XBRL and gives developers a strong foundation for implementing XBRL solutions.

"The XSB continues to deliver against the strategic plan, including increased comparability, making XBRL easier to use, reducing the barriers to XBRL software development. The public working draft is a key component of that and we encourage market feedback”, said XSB Chair Conor O’Kelly.

The XII Abstract Model includes use case diagrams, class diagrams, object diagrams, and sequence diagrams and is a key component of Preserve Promote Participate, the strategic core vision developed by the XBRL Standards Board to continue the momentum of the XBRL standard.
