EuroPLoP2008 sparked a conversation about the need and possibilities for coordinating efforts in constructing software systems for authoring, storing, sharing, searching and using design patterns and pattern languages. Such systems include:

• (Collaborative) pattern editors, e.g. the Planet pattern tool.
• Pattern repositories, e.g. PatternForge.
• Aggregators and search engines, e.g. PatternSeer
• Formal languages, e.g. PLML
