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
