it is crucial to
provide support in order to establish the trustworthiness of
knowledge artefacts. The solution proposed is designed following the original semantic web stack architecture[1] and
uses existing and emerging W3C semantic web standards
such as RDF [16], OWL[14], and SWRL[19]. The WebOf-
Patterns [22] project is presented in a case study. This
includes an Eclipse based WebOfPatterns client that can
be used to discover design pattern definitions in social net-
works, to define and publish patterns, to rate patterns, to
establish the trustworthiness of patterns found, and finally
to x-ray Java projects for instances of discovered patterns.
