  2. Platform and Plugin • PlatformIn computing, a platform describes some sort of hardware architecture or software framework (including application frameworks), that allows software to run. Typical platforms include a computer's architecture, operating system, programming languages and related runtime libraries or graphical user interface. • Plugin • In computing, a plug-in (also called plugin, addin, add-in, addon, add-on, snap-in or snapin) consists of a computer program that interacts with a host application (a web browser or an email client, for example) to provide a certain, usually very specific, function "on demand". Add-on is often considered the general term comprising plug-ins, extensions, and themes as subcategories.

  3. Purpose • To enable third-party developers to create capabilities to extend an application • To support features yet unforeseen • To reduce the size of an application • To separate source code from an application because of incompatible software licenses

  4. Example • Boost Extension, Boost C++ plug-in framework, available from boost sandbox. • Qt Plug-Ins, part of Nokia's Qt Framework. • Java Plug-in Framework(JPF), a plug-in mechanism adapted from Eclipse's plug-in mechanism from its pre-OSGi era. • OSGi, a standardized dynamic component system suited for plug-in programming, used in Eclipse, many commercial J2EE application servers, Spring Framework, and embedded applications. • Rich Client Platform (RCP), platform for applications adapted from Eclipse, applications are written as plug-ins and may themselves have further plug-ins
