Pattern Languages of Programs
Pattern Languages of Programs is the name of a group of annual conferences sponsored by The Hillside Group. The purpose of these conferences is to develop and refine the art of software design patterns. Most of the effort focuses on developing a textual presentation of a pattern such that it becomes easy to understand and apply. This is typically done in a writers' workshop setting.
The flagship conference
The flagship conference is called the Pattern Languages of Programs conference, abbreviated as PLoP. PLoP has been held in the U.S.A. since 1994. Until 2004 it was held annually at Allerton Park in Monticello, Illinois, a property of the University of Illinois at Urbana Champaign. Since then, its location has alternated between Allerton park and being co-located with OOPSLA, a large computer science conference, with the Agile Conference in 2009, and with PUARL in 2018. The 27th PLoP will be held in Keystone, Colorado.Notable people who chaired the conference in the past include Ward Cunningham, Richard Gabriel, Ralph Johnson, John Vlissides and Kent Beck.
PLoP are sponsored by The Hillside Group, a U.S.-based non-profit organization that holds the PLoP trademark and the rights to the conference.
