  Communication and interaction among agents have been the subject of extensive
investigation since many years. Commitment-based communication, where
communicating agents are seen as a debtor agent who is committed to a creditor
agent to bring about something (possibly under some conditions) is now very
well-established. The approach of DACMAS (Data-Aware Commitment-based MAS)
lifts commitment-related approaches proposed in the literature from a
propositional to a first-order setting via the adoption the DRL-Lite
Description Logic. Notably, DACMASs provide, beyond commitments, simple forms
of inter-agent event-based communication. Yet, the aspect is missing of making
a MAS able to acquire knowledge from contexts which are not agents and which
are external to the MAS. This topic is coped with in Managed MCSs (Managed
Multi-Context Systems), where however exchanges are among knowledge bases and
not agents. In this paper, we propose the new approach of DACmMCMASs
(Data-Aware Commitment-based managed Multi- Context MAS), so as to obtain a
commitment-based first-order agent system which is able to interact with
heterogeneous external information sources. We show that DACmMCMASs retain the
nice formal properties of the original approaches.
