Different communities of software agents may address different predefined concerns; some of these concerns may also be the result of combining two or more sub-concerns. In the research, the authors look at a concern as the abstract concept a community of agents is continually supporting as long as certain objectives are being accomplished. Besides, a sub-concern is a generically narrower concept of a community's abstract concern, which is satisfied whenever a specific set of objectives is being achieved. In this paper, they introduce a formal description of the setting wherein they expect software agents to negotiate over service exchange, (i.e., acquisition and provision).
