Ripple: Functional Programs as Linked Data

Ripple is a scripting language expressed in RDF lists. Its scripts both operate upon and are made up of RDF metadata, extending the idea of HTTP dereferenceability to computation. Ripple is a variation on the ”concatenative” theme of functional, stack-oriented languages such as Joy and Factor, and distinguishes itself through a multivalued, ”pipeline” approach to query composition, as well as the inherent distributability of its programs. The Java implementation of Ripple includes a query engine, a provisonal assortment of primitive functions, and an interactive interpreter which parses commands and queries in a readable, Turtle-like format.
