SOPlets
Soplets is a method of describing semantic concepts as blocks of code, using existing features of the (Java) language, namely annotations and enumerations. Each block of code (called Soplet) represents all properties and features of a given concept (as far as reasonable and feasible), including features outside of the traditional modelling scope, such as translations, documentation, requirement tracking and so on.
Soplets can be referenced and used from anywhere inside the code. Given the strong-typed nature of the references they can be safely refactored as seen fit.
A Soplet may be exhanced by one or more (stateless) functions, which are directly attached to the code block. That way also related features related to a given concept (such as calculations, validation, transformations etc.) beyond pure key-value pairs may be associated with a given Soplet.
The structure of a Soplet is formally defined by the stereotype it implements. This stereotype may be individually composed of several aspects (such as Translatable, Beanable, Bindable, Testable etc.), which in turn may be freely defined by the developer (or which are part of a framework which he uses).
An open-source plugin (based on the Project Lombok plugin) allows the creation of byte-code during compile-time, based on the information contained in the Soplets. For instance, a data bean may have all of its attributes, getters and setters generated.
