normative actions is presented. In the last two columns we indicate whether or not the
MOISE+ model and MSPP Framework support such normative action.
For example, observe in Table 1 that only the norm “Acquire cupboard” is supported
by the MOISE+ organizational model, since there is no periodicity in this action, i.e.,
it occurs just once. The gardener, when acquiring its plot in HSJ, has the right to have
a cupboard to store utensils, tools or materials for general use. In MOISE+, this task's
execution occurs through the realization of this mission on the first day and ends by
indicating its satisfiability level, which indicates that the goal has already been achieved,
in this case, “satisfied”.
Also in Table 1, the “Monthly Payment” norm states that a gardener should pay a
monthly tax if he/she has a cultivation parcel. This norm is an obligation one, with a
monthly periodicity. This type of norm can not be modeled by MOISE+, since it does
not have structures to natively allow the description of norms and routines, as described
in Section 3. For that, we propose the use of the MSPP framework, since it better suits
this task, having structures (the Periodicity parameter) that allow such normalization of
periodic actions, as discussing in section 3.4.
Thus, the analysis of routines in the San Jerónimo Vegetable Garden allows us to
observe that due to the periodicity of the the routines and norms, as shown in Table 1,
using only the MOISE+ model it is not possible to complete the modeling of the or-
ganization. However, the use the MSPP framework proved to be adequate, meeting the
need that the system requires. Then, we propose to use those tools in a combined way,
such that the norms are specified in the MSPP framework, which support periodicity,
and the normalized routines in the MOISE+ model.

Conclusion and Further Works
The JaCaMo platform has resources that make it a fully-fledged platform for modeling
multiagent systems, including social systems. However, for the case study of this pa-
per, some limitations could be observed related to MOISE+ model, with respect to the
modeling of routines, namely, periodic routines and norms. In the case study of HSJ,
several actions are periodic, which is very common in social systems and even in other
types of systems.
The specification of routines could not be done in MOISE+, making necessary the
use of another tool. In this paper, we propose to use the MSPP framework. The use
of this framework enabled the specification of normative actions of the organizational
roles, offering a more modular specification like other aspects pertaining to a MAS
(organization, population and environment, already treated in JaCaMo). Besides that, it
allows its modification according to conditions evaluated by agents, in their routines.
For example, irrigation is not necessary if it has rained.
We emphasize that the features of the framework complements those provided by
the MOISE+ model, where goals and actions can be described hierarchically. The de-
scription of the periodicity is made in the framework and the actions are specified in
MOISE+.
In Figure 4, a proposal for future work is presented. We intend to integrate different
types of artifacts (Organizational, Regulatory, Communication and Physical), for the
domain of HSJ.
