We present a language Scc for a specification of the direct exchange and/or the global sharing of information in multi-agent systems. Scc is based on concurrent constraint programming paradigm which we modify in such a way that agents can (i) maintain its local private store, (ii) share (read/write) the information in the global store and (iii) communicate with other agents (via multi-party or hand-shake). To justify our proposal we compare Scc to a recently proposed language for the exchange of information in multi-agent systems. Also we provide an operational semantics of Scc. The full semantic treatment is sketched only and done elsewhere. (full and enlarged version of SOFSEM'01 conference paper).
