Al-Risalh is an Arabic pure object-orientedprogramming language that has the basic mechanisms of object-orientation, objects, classes, and messages. Also the language has the full support of object-orientation concepts. The Al-Risalh language supports application programming as well as systemsprogramming. This paper introduces the language that can used to teach Arabic-speaking students, how to program and how to understand the basic concepts to the idea of object-orientedprogramming.

Software design patterns are the core abstractions from successful recurring problem solutions in software design. Composite design patterns are the core abstractions from successful recurring frameworks. A composite design pattern is a pattern that is best described as the composition of further patterns the integration of which shows a synergy that makes the composition more than just the sum of its parts. This paper presents examples of composite patterns, discusses a role-based analysis and composition technique, and demonstrates that composite patterns extend the pattern idea from single problem solutions to object-oriented frameworks.

The design and specification of an extensible class library presents a difficult challenge: because extensibility comes from allowing the user to override parts of the implementation, more of the internal structure must be exposed to the user than in a typical procedure library. This raises issues in both how the library is designed and how its specification is written. Specification of the CLOS Metaobject Protocol required a combination of new and existing techniques to address these issues. We present those techniques, and discuss their relation to the underlying issues.
