The Web of Patterns Project

The WebOfPatterns (WOP) is a toolkit that facilitates the sharing of knowledge about software design. WOP consists of two parts: a language neutral format to describe design patterns based on the W3C standards RDF and OWL , and a set of Eclipse plugins which use this format.

How WOP can be used:

  1. Find pattern instances in Java programs (pattern x-ray), and process the instances found (e.g. in reports). Read more.
  2. You have a good design and want to share it with others. Use the WOP "extract and publish" wizard to extract the pattern, generate the pattern definition and publish it. Let people now about this by adding a bookmark, blog it or submit your pattern to a search engine. Read more.
  3. Find patterns online. WOP can find patterns listed/bookmarked/mentioned by search engines, blogs and bookmarking services. You can add them to your pattern repository. You can use rules to define the trustworthiness of patterns. For instance, you might only be interested in Gang of Four patterns (patterns where the DC Creator annotation includes the Gang of Four members), patterns from sources using https, or patterns bookmarked by more than 10 users on Read more.
  4. Rate patterns. Tell others what you think about a pattern. Give it a rating, or add a delicious bookmark. Others can use this information to decide whether a pattern is good or not. Read more.
  5. If you want to do something else with patterns, consider joining or project. Here are some ideas we have: visualising patterns, pattern instances and aggregated pattern instances. Or using patterns as templates. Looking into refactorings and antipatterns.


Open source, can be downloaded from source forge. Eclipse 3.2 or better (or any product based on such a version of Eclipse), and Java 5 are required. Access to source code is possible via Subversion.

Project Status:

Eclipse plugin 1.3.0 released (18 March 07) with built in pattern and pattern instance visualisation based on DPML, and a new open pattern/ pattern instance export facility.
