  abstract: "Subject-oriented programming supports composition of object-oriented programs or program fragments called subjects. This paper presents an approach to the composition rules used to specify composition details. Rules can be generic, allowing different subrules to be \"plugged into\" higher-level rules, and they include a means of specifying exceptions to general rules. We give definitions of a number of useful, generic rules, including merge and override, as a first step towards a generally-useful composition rule library. We also outline an object-oriented framework for implementing rules, which we are currently building as part of our support for subject-oriented programming in C++."

  abstract: "Tools and environments to aid developers in producing software have existed, in one form or another, since the early days of computer programming. They are becoming increasingly crucial as the demand for software increases, time-to-market decreases, and diversity and complexity grow beyond anything imagined a few decades ago. In this paper, we briefly review some of the history of tools and environments in software engineering, and then discuss some key challenges that we believe the field faces over the next decade."

  abstract: "In practice, object-oriented design models have been less useful throughout the lifetime of software systems than they should be. Design models are often large and monolithic, and the structure of the designs is generally quite different from that of requirements. As a result, developers tend to discard the design, especially as the system evolves, since it is too difficult to keep its relationship to requirements and code accurate, especially when both are changing. This paper presents a different approach to designing systems, based on flexible decomposition and composition, that closely aligns designs with both requirements specifications and with code. We illustrate how this approach permits the benefits of designs to be maintained throughout a system’s lifetime."

  abstract: "Object-Oriented technology is often described in terms of an interwoven troika of themes: encapsulation, polymorphism, and inheritance. But these themes are firmly tied with the concept of identity. If object-oriented technology is to be successfully scaled from the development of independent applications to development of integrated suites of applications, it must relax its emphasis on the objecf. The technology must recognize more directly that a multiplicity of subjective views delocalizes the concept of object, and must emphasize more the binding concept of identity to tie them together. This paper explores this shift to a style of object-oriented technology that emphasizes the subjective views: Subject-Oriented Programming."

  abstract: "Done well, separation of concerns can provide many software engineering benefits, including reduced complexity, improved reusability, and simpler evolution. The choice of boundaries for separate concerns depends on both requirements on the system and on the kind(s) of decompositionand composition a given formalism supports. The predominant methodologies and formalisms available, however, support only orthogonal separations of concerns, along sdngle dimensions of composition and decomposition. These characteristics lead to a number of well-known and difficult problems. This paper describes a new paradigm for modeling and implementing software artifacts, one that permits separation of overlapping concerns along multiple dimensions of composition and decomposition. This approach addresses numerous problems throughout the software lifecycle in achieving wellengineered, evolvable, flexible software artifacts and traceability across artifacts."
