Background

This web page is maintained by Frank Lopez.

After designing and developing CLIPS 1.0 in 1985 for NASA, Mr. Lopez created several other rule-based languages.

• CLIPS 1.0

  • NASA CLIPS 1.0 was created in the Spring of 1985 while Mr. Lopez was a NASA CO-OP employee.

  • NASA, Johnson Space Center, Houston, Texas, 1985

  • NASA CLIPS 1.0 was created on the second floor of NASA's Mission Control Center building in Houston. It was literally created within 30 feet of the Mission Control consoles you see on television, or may have seen in person if you have visited the Johnson Space Center in Houston.

  • The first CLIPS rule fired in March 1985 on an HP 9000 running UNIX.

  • The first real program coded using CLIPS was developed by the Purdue University Electrical Engineering department in 1985.

• CLIPS-2

  • Purdue University, 1985-1986
