We are continuously monitoring the COVID-19 pandemic from local authorities and the World Health Organization. PLoP 2020 is still many months away, and as we monitor we will decide if it will be held in September, as currently planned, at the Keystone Resort.

PLoP 2020 will be chaired by Rebecca Wirfs-Brock. PLoP is shaping up to be, once again, a great experience. Check back as the program is updated with more details!

PLoP will be held at the Keystone Resort in Colorado in conjunction with the ExploreDDD Conference. The PLoP conference starts on the evening of Monday, September 14, with the traditional games and dinner and it will conclude on Thursday afternoon, September 17.

The BootCamp, a special full-day Pre-PLoP activity for newcomers, will happen during Monday, September 14.

The International Conference on Pattern Languages of Programs

Pattern Languages of Programs (PLoP) conference is a premier event for pattern authors and pattern enthusiasts to gather, discuss and learn more about patterns and software development.

The conference program offers pattern authors an unique opportunity to have their pattern languages reviewed by fellow authors, which occurs mainly in the form of Writers' Workshops.

Authors and non-authors will find in the different PLoP activities (Writers' Workshops, Focus Groups, BoF sessions, BootCamp, Games) many opportunities to learn more about patterns and pattern writing.

As a whole, the conference provides a friendly and effective environment to give and get feedback, to share expertise, and to allow the participants to improve their patterns and make them more useful and more publishable.

Call For Submissions

PLoP promotes development of pattern languages on all aspects of software, including design and programming, software architecture, user interface design, domain modeling, software processes, project management, and more. As well as software patterns, we encourage patterns about collaboration, education, and creativity in broader sense toward better quality of work and life.

Paper submissions may include short papers containing one or more patterns, longer pattern languages or sequences, or works-in-progress by writers wishing to get in-depth shepherding by an experienced author at the conference. Patterns and pattern languages on other topics, essays on patterns, and visions for the future are encouraged.

In addition, you may submit proposals for free-format discussion groups or workshops bringing together people interested in a hot topic related to patterns or proven practices—with a duration about two hours. Non-conventional formats are welcome.

Suggestions or proposals for activities are welcome and encouraged. Please contact the chairs with your ideas.

PLoP20 submissions are peer reviewed and digitally archived at ACM. Papers discussed at writer's workshop at this conference qualify for submission to the journal "TPLoP - Transactions on Pattern Languages of Programming" published by Springer. See Springer's pages on TPLoP for details of this journal.
