Q: What is Oz primarily used for?

A: Oz is used for constraint programming and general-purpose development across several paradigms, including concurrent and functional programming. Its design supports writing programs that combine constraint solving with other styles.

Q: Who created Oz and when was it created?

A: Oz was designed by Gert Smolka and was first introduced in 1991.

Q: Is Oz open source and where can I find its implementation?

A: Oz is distributed under the MIT License. The Mozart/Oz project provides implementations and releases; a stable release (Mozart2 v2.0.1) was published on 2018-09-05 and project resources are available at the official website and repository links.
