We study services modeled as
open workflow nets
(oWFN) and describe their behavior as
service automata
. Based on arbitrary finite-state service automata, we introduce the concept of an
operating guideline
, generalizing the work of [1,2] which was restricted to acyclic services.
An operating guideline gives complete information about how to properly interact (in this paper: deadlock-freely and with limited communication) with an oWFN
N
. It can be executed, thus forming a properly interacting partner of
N
, or it can be used to support service discovery.
An operating guideline for
N
is a particular service automaton
S
that is enriched with Boolean annotations.
S
interacts properly with the service automaton
$\mathit{Prov}$
, representing the behavior of
N
, and is able to simulate every other service that interacts properly with
$\mathit{Prov}$
. The attached annotations give complete information about whether or not a simulated service interacts properly with
$\mathit{Prov}$
, too.
