Design patterns indicate the efficient solutions to common re-occurring problems in software engineering that have been cataloged for the benefit of object-oriented (OO) architecture and design. Patterns are becoming omni-present in the area of OO design. However, a detailed analysis of appropriate specification methods to represent patterns has not been made so far. This project aims at:

• To formulate the requirements of an "ideal" methodology for pattern specifications.
• To identify the basic building blocks of OO design and provide a proper vocabulary to them.
• To establish a precise and a formal language to represent and specify s/w design patterns using the basic building blocks.
• To use the proposed language in:
  • Automatic pattern mining
  • Detection of pattern variants
  • Precisely specifying the computation by the notion of "pattern signature"
