On September 28, 2009 the second beta release of IFC2x4 has been published. Today I'd like to encourage all to actively participate in the public review process, the deadline for IFC2x4 beta 2 review is November 21, 2009. See http://www.iai-tech.org/projects/ifc-roadmap for an updated road map for the IFC2x4 development period.

We look for all issues that can be raised, particularly however for improvements of the documentation and clarity of reading the specification. So please don't hesitate to also log issues when the documentation is not clear, unambiguous or missing clarity. Also, please note that the IFC2x4 beta2 release marks the feature freeze and major schema update freeze for IFC2x4.

The IFC2x4 beta 2 release can be characterized as:

• The IFC 2x edition 4 release (IFC2x4), combines a number of feature increases with some major rework and improvements of the existing IFC specification. It has been developed as the next basis for IFC enabled interoperability of Building Information Models. It is also intended that the IFC2x4 release will be submitted to the International Standardization Organization (ISO) for approval as a full International Standard ISO16739.
