The American Institute of Architects has issued a statement endorsing open standards and encouraging its members to take an active role in adopting it.
“The AIA believes that all industry-supporting software must facilitate, not inhibit, project planning, design, construction, commissioning and lifecycle management. This software must support non-proprietary open standards for auditable information exchange and allow for confident information exchanges across applications and across time.

This is best accomplished through professional, public- and private sector adoption of open standards. The AIA encourages its members and other industry organizations to assume a leadership role in the ongoing development of open standards..”
