Results from SC for CAD data exchange
SXF (SCADEC data eXchange Format)
To satisfy that 3-dimensional geometric feature is completely exchanged.
Level1 To satisfy that drawing image is reproduced accurately on screen (and paper).
To satisfy that 2-dimensional CAD data is completely exchanged among various CAD software, thus satisfies the requirements for e-Delivery
To satisfy that product model data is exchanged among CAD and related software including GIS and construction cost estimation.

Toward soft standards
• Hard (strict) standards– difficult to change often– difficult to include new technological advancement– difficult to apply wide variety of systems
• What is soft standard– Independent to individual application, database structure
• Object oriented data model• Described in XML• Standard application interface
– High transparency and accessibility• Metadata registory• Clearing house• One stop portal
Toward open/consensus standard
• De jure standard– Strict authorization process– Take long time to standardize
• De facto standard– Specification details are not necessarily accessible– Maintenance of the standard is not insured
• Open/consensus standard– Accessible to everyone– Transparent (fully documented and open)– Determined and maintained through consensus– Simple authorization process
