The STEP Class Library (SCL) was developed by the Manufacturing

Systems Integration Division at NIST to support testing of the

Standard for the Exchange of Product Model Data (a.k.a STEP) and

validation of STEP's emerging implementation specifications. Funding

for the project has come from the Department of Commerce and the

Department of Defense agencies including the Office of the Defense

CALS (Continuous Acquisition and Life-Cycle Support) Executive and

the Defense Advanced Research Projects Agency (DARPA). Recent

enhancements were sponsored by the National Information Infrastructure

Protocols Consortium and NIST's Systems Integration for Manufacturing

Applications (SIMA) program.
