A Body of Knowledge (BoK) is an ontology for a particular professional domain. A Community of Practice (CoP) is the collection of people developing such knowledge. In the paper we explore these concepts in the context of the formal methods community in general and the Z notation community, as has been supported by the Z User Group, in particular. The existing SWEBOK Software Engineering Body of Knowledge is considered with respect to formal methods and a high-level model for the possible structure of of a BoK is provided using the Z notation.
