You won't want to miss this opportunity to meet researchers, educators, and practitioners whose interests span a remarkably broad range of topics and who share an interest in exploring the power of the pattern form.

The SugarLoafPLoP 2007 program will offer tutorials, keynotes, and three different tracks of papers:

* Writers' Workshops (WW) - for papers that document patterns and pattern languages (design patterns, process patterns, etc.).

* Pattern Applications (PA) - for papers that explore the application of patterns or that are about patterns, for example, using patterns in industry or academia, tools for using patterns, comparisons of productivity when using patterns.

* Writing Patterns (WP) - for papers by newcomers who want to learn how to better elaborate an idea intended to evolve to a pattern. This is more a hands-on tutorial on writing patterns.

Software developers have long observed that certain themes recur and endure across different applications and systems. The emerging interest in patterns represents an effort to catalog and communicate these themes to provide handbooks of proven solutions to common problems.

We invite you to add your expertise to the growing corpus of patterns. SugarLoafPLoP focuses on improving the expression of patterns. You will have the opportunity to refine and extend your patterns with help from knowledgeable and sympathetic fellow patterns enthusiasts. You will also be able to discuss applications of patterns in industry and academia.

SugarLoafPLoP will be held at Hotel Pontal de Ocaporã in Porto de Galinhas, only fifty minutes from Recife.

Porto de Galinhas is one of the most beautiful beaches of Brazil. (http://www.portodegalinhas.com.br). See more about Pernambuco and its beaches here.
