Abstract. This paper describes a community of practice on concept mapping that has been established in Turin, Italy by
DSCHOLA. The main purpose of the community is to differentiate the various forms of knowledge representation from each other and to recover the general function of the knowledge representation connected with the learning environment. As a starting
point, the community defined and shared a set of founding documents, which includes the Manifesto and the Documentation template. The community aims at structuring and organizing selective criteria in order to produce and make available documentations dealing with good practices on concept mapping.

Not necessarily a rigorous paper, but it shows what I call "nucleation" pretty well.
