Extensively used within the Wolfram System itself, the Wolfram Symbolic Transfer Protocol (WSTP) is the Wolfram System's unique high-level symbolic interface standard for interprogram communication. With convenient bindings for a variety of languages, WSTP immediately allows arbitrary symbolic objects—representing data, programs, or any other construct—to be efficiently exchanged between programs, on one computer or across a heterogeneous network.
