Developing and monitoring communities has become increasingly easy on the web as the number of interactive facilities and amount of data available about communities increases. It is possible to view connections on social and professional networks in the form of mathematical graphs. It is also possible to visualise connections between authors of academic papers. For example, Google Scholar, Microsoft Academic Search, and Academia.edu, now have large corpuses of freely available information on publications, together with author and citation
details, that can be accessed and presented in a number of ways. In mathematical circles, the concept of the Erdős number has been introduced in honour of the Hungarian mathematician Paul Erdős, measuring the collaborative distance" of a person away from Erdős through links by co-author. Similar metrics have been proposed in other fields. The possibility of exploring and
improving the presentation of such links online in the sciences and other fields will be presented as a means of improving the outreach and impact of publications by academics across
different disciplines. Some practical guidance on what is worthwhile in presenting publication information online are given.

Editor's Notes
Introduction
A Body of Knowledge (BoK) is an ontology for a particular professionaldomain. A Community of Practice (CoP) is the collection of people developingsuch knowledge. In the paper we explore these concepts in the contextof the formal methods community in general and the Z notation community, ashas been supported by the Z User Group, in particular. The existing SWEBOKSoftware Engineering Body of Knowledge is considered with respect to formalmethods and a high-level model for the possible structure of of a BoK is providedusing the Z notation.
CoP books.
1. Domain: A CoP must have a common interemethodsst to be effective. All the participants inthe group must be able to contribute in some way within this domain. Otherwise itis just a collection of people with no particular purpose. For example, the Z notationhas formed the nucleus of a CoP in a formal context.2. Community: A CoP also needs a group of people who are willing to engage withat least some others in the group, so ultimately the entire group is transitively connectedas a single entity, from a global viewpoint. This aspect is critical to theeffective development of knowledge. The group of people interested in the Z notationstarted at the Oxford University Computing Laboratory through the inspirationof Jean-Raymond Abrial in the late 1970s and early 1980s. It has gradually spreadaround the world since then.3. Practice: The CoP must explore both existing knowledge and develop new knowledge,based on existing concepts, but expanded through actual application in apractical sense. This leads to a set of common approaches and shared standardsin applying them. The Z notation is based on predicate logic and set theory, bothvery standard concepts in mathematics that were originally formulated a long timebefore the development of Z. Schema boxes were added to the mathematics for theconvenient structuring of realistic specifications. Initially case studies were specified.More recently, Z has been used for major industrial software engineeringprojects of a significant scale where system integrity is an important factor.
1. Design the CoP to evolve naturally: communities are naturally dynamic and theability to adapt to the current needs of the CoP at different points in its developmentis important.2. Create opportunities for open discussion: often an outsider can add value to theCoP by bringing in ideas that may not have evolved in the community if it wascompletely isolated.
