The sample pattern library contains an appropriate selection of patterns to showcase the primary pattern authoring and patterns framework concepts. A few of the patterns also use less common parameter types to highlight the treatment of these types (such as enumerations and UML literals). Some sample patterns are included to highlight additional features that are available to pattern authors in the implementation of their patterns.
In addition, pattern authors can create a patterns library example project under the new example plug-in project (UML modeler plug-in examples section) to learn how to create patterns by examining the sample source. The patterns can then be modified and would subsequently show up in the Pattern Explorer view of another run-time instance of the product.
