O que (quem) é subject-oriented programming - definição

In computing, subject-oriented programming is an object-oriented software paradigm in which the state (fields) and behavior (methods) of objects are not seen as intrinsic to the objects themselves, but are provided by various subjective perceptions ("subjects") of the objects. The term and concepts were first published in September 1993 in a conference paperWilliam Harrison and Harold Ossher, Subject-Oriented Programming - A Critique of Pure Objects, Proceedings of 1993 Conference on Object-Oriented Programming Systems, Languages, and Applications, September 1993 which was later recognized as being one of the three most influential papers to be presented at the conference between 1986 and 1996.

<programming> Program composition that supports building object-oriented systems as compositions of subjects, extending systems by composing them with new subjects, and integrating systems by composing them with one another (perhaps with glue or adapter subjects). The flexibility of subject composition introduces novel opportunities for developing and modularising object-oriented programs. Subject-oriented programming-in-the-large involves dividing a system into subjects and writing rules to compose them correctly. It complements object-oriented programming, solving a number of problems that arise when OOP is used to develop large systems or suites of interoperating or integrated applications. {IBM subject-oriented programming (http://research.ibm.com/sop/)}.
