A Methodological, Philosophical, and
Educational Study on Pattern LanguagesPLoPourri

Organizers: Takashi Iba, Joseph Yoder, Richard Gabriel

Dates: Jan/Feb, 2022 (see below)

Abstract: Takashi Iba is currently writing an academic book (in Japanese) on pattern languages. Over the last year, the Iba lab has revised their method to create pattern languages and with these papers, is sharing knowledge about their experiences with it. This workshop focuses on seven papers on Methodological, Philosophical, and Educational studies on Pattern Languages.

In this workshop, we will discuss these papers with the goals of improving their (English) presentation and validating their content. The format will be a gently guided (Socratic) discussion over a span of a few days. This is an invitation-only workshop.
