open distributed processing — (standard) (ODP) An attempt to standardise an OSI application layer communications architecture. ODP is a natural progression from OSI, broadening the target of standardisation from the point of interconnection to the end system behaviour. The objective of ODP is to enable the construction of distributed systems in a multi-vendor environment through the provision of a general architectural framework that such systems must conform to. One of the cornerstones of this framework is a model of multiple viewpoints which enables different participants to observe a system from a suitable perspective and a suitable level of abstraction.

polymorphic lambda-calculus — (language, types) (Or "second order typed lambda-calculus", "System F", "Lambda-2"). An extension of typed lambda-calculus allowing functions which take types as parameters. E.g. the polymorphic function "twice" may be written: twice = /\ t . \ (f :: t -> t) . \ (x :: t) . f (f x) (where "/\" is an upper case Greek lambda and "(v :: T)" is usually written as v with subscript T). The parameter t will be bound to the type to which twice is applied, e.g.: twice Int takes and returns a function of type Int -> Int. (Actual type arguments are often written in square brackets [ ]). Function twice itself has a higher type: twice :: Delta t . (t -> t) -> (t -> t) (where Delta is an upper case Greek delta). Thus /\ introduces an object which is a function of a type and Delta introduces a type which is a function of a type. Polymorphic lambda-calculus was invented by Jean-Yves Girard in 1971 and independently by John C. Reynolds in 1974.
