Fedora open source software gives organizations a flexible service-oriented architecture for managing and delivering their digital content. At its core is a powerful digital object model that supports multiple views of each digital object and the relationships among digital objects. Digital objects can encapsulate locally-managed content or make reference to remote content. Dynamic views are possible by associating web services with objects. Digital objects exist within a repository architecture that supports a variety of management functions. All functions of Fedora, both at the object and repository level, are exposed as web services. These functions can be protected with fine-grained access control policies.
It is possible in Javascript (ECMAScript) to do classical single inheritance nested to any depth, without any caveats.
This article concisely explores the mechanism in depth, including flaws in other approaches, internal Javascript algorithms, proper OOP data encapsulation with default constructors, and an optimized inheritance declaration syntax with both Object and Function prototype convenience methods.
Xholon enables you to model dynamic event-driven applications using concepts from the Unified Modeling Language (UML 2) and from Real-Time Object-Oriented Modeling (ROOM) (inheritance, composite structure, ports, state machines, etc.) expressed in XML, XP

Infer Type is a new Eclipse refactoring that helps you decouple your code. If you have already made use of Eclipse refactorings, Infer Type is best introduced as a sibling to Extract Interface, Generalize Type, and Use Supertype Where Possible. However, i
Old, but very good article on Singleton (and OO) misunderstand/misuse. From my opinion, a second edition (e.g. "Patterns revisited") of the Patterns book is necessary, though it's horrible that Mr. Vlissides has passed away.
