  Norm emergence is typically studied in the context of multiagent systems
(MAS) where norms are implicit, and participating agents use simplistic
decision-making mechanisms. These implicit norms are usually unconsciously
shared and adopted through agent interaction. A norm is deemed to have emerged
when a threshold or predetermined percentage of agents follow the "norm".
Conversely, in normative MAS, norms are typically explicit and agents
deliberately share norms through communication or are informed about norms by
an authority, following which an agent decides whether to adopt the norm or
not. The decision to adopt a norm by the agent can happen immediately after
recognition or when an applicable situation arises. In this paper, we make the
case that, similarly, a norm has emerged in a normative MAS when a percentage
of agents adopt the norm. Furthermore, we posit that agents themselves can and
should be involved in norm synthesis, and hence influence the norms governing
the MAS, in line with Ostrom's eight principles. Consequently, we put forward a
framework for the emergence of norms within a normative MAS, that allows
participating agents to propose/request changes to the normative system, while
special-purpose synthesizer agents formulate new norms or revisions in response
to these requests. Synthesizers must collectively agree that the new norm or
norm revision should proceed, and then finally be approved by an "Oracle". The
normative system is then modified to incorporate the norm.
