The goal of the Object Pascal Foundation, or OPF, it to advance and promote the world-wide adoption of programming languages which use Object Pascal as their origin and for their core principles.
Object Pascal is based on the Pascal programing language invented in 1970 by Niklaus Wirth, but has come along way since that time. Popular Object Pascal implementations currently in use are Delphi, Oxygene and Free Pascal.
