Software awareness has become an important requirement in the construction of self-adaptive systems. As such, the software should better adapt to changes in the various environments in which they operate, be aware of (in the sense of perceiving and understanding) these environment and be aware of its own operation in these environments. However, even at a basic level applied to software, awareness is a requirement difficult to define. Our work proposes the creation of a catalog to the awareness requirement through non-functional requirements patterns (NFR patterns). We also propose mechanisms for enabling the instantiation and use of the knowledge about awareness, represented in this catalog.
