abstract = {Service orchestrations are a common means to compose individual services to
either higher-level services or potentially complex composite applications. The
Web Service Business Process Execution Language (WS-BPEL) is an example for a
language that allows for de - ning automatically executable orchestrations of
Web services. As of today, BPEL process are typically executed in a centralized
manner; the process model is deployed on a single work ow management system
which, during process instance execution, interprets the process de nition and
interacts with the orchestrated Web services on behalf of the user. In previous
work, we have presented an approach which enables decentralized execution of
BPEL processes based on a decentralized process model and supporting runtime
infrastructure. In this paper we describe a method for automatic splitting of a
process among the partners participating in its execution, referred to as
process partitioning.},

combinations of qualities of services (QoS) at middleware level. The scenario
presented in the paper, for instance, requires transactional middleware
behaviour for business negotiations between a relatively small number of
participants on the one hand, while on the other hand it requires high
scalability for distributing data to a large number of clients. The concept of
Triple Space, a semantically enhanced, distributed tuplespace middleware based
on an extended Linda model, has been developed to provide such an
infrastructure. In contrast to existing middleware infrastructures, Triple
Space supports a set of configurations which define the system’s QoS. In this
paper, we present a motivating use case scenario, deduce requirements for the
architecture of Triple Space, define its architecture and three QoS
configurations, and outline our approach towards implementing a highly scalable
distributed communication infrastructure.},

abstract = {Petri nets are a formalism for describing systems where interactions between
active components -- so-called transitions -- are modeled as exchanges of
tokens over passive places. Whether a transition may fire is solely dependent
on the availability of tokens in its incoming places; similarly a transition
forwards control to subsequent transitions by storing tokens in their
respective input places. This interaction model of strong decoupling through
local actions and local effects makes distributed systems modeled via Petri
nets highly extensible. In this paper, we present the syntax and semantics of a
model that leverages the extensibility provided by Petri nets for representing
BPEL processes in a way that enables their distributed and decentralized
execution using tuplespace middleware. Said middleware implements the proposed
Petri net dialect and therefore allows for direct, distributed execution of the
modeled processes.},

abstract = {Decentralized workflow enactment -- the process of evaluating control flow in a
distributed manner -- is a key aspect of the implementation of a decentralized
workflow management system (WfMS). A major challenge in this field is the
support for join operations to synchronize concurrent threads of control flow.
The original Linda model however does not provide operations for matching more
than one tuple in a single operation -- complex logic needs to be implemented
on the client side, having severe impact on performance and breaking the
concept of coordination languages by mixing coordination and application logic.
In this paper, we stress the need for an extended tuplespace model that
natively supports the sync operation realizing WS-BPEL synchronizing joins
directly on the tuplespace level. We pay special attention to the description
of its semantics and propose an algorithm for efficient implementation on a
single tuplespace. For the common case in distributed workflow enactment, where
control flow is distributed over multiple tuplespaces, we present an
optimization of the aforementioned algorithm in form of the sync pattern.},

abstract = {The most prominent business process notations in use today are BPMN, EPC and
BPEL. While all those languages show similarities on the conceptual level and
share similar constructs, the semantics of these constructs and even the
intended use of the language itself are often quite different. As a result,
users are uncertain when to use which language or construct in a particular
language, especially when they have used another business process notation
before. In this paper, we discuss the core characteristics of graph-based and
block-structured modelling languages and compare them with respect to their
join and loop semantics.},

abstract = {Petri Nets are a formalism for describing coordinated interactions between
independent entities, called transitions, by means of synchronized token
exchange through places. Tuplespaces are an abstraction of the shared memory
concept providing means for loosely-coupled coordination between individual
components. In the tuplespace model, coordination between applications is
achieved by production and blocking consumption of tuples which are
communicated over tuplespace buffers. On the basis of the conceptual
similarities of Petri nets and tuplespaces, we investigate in this paper
whether tuplespaces are a suitable platform for execution of applications
modeled as Petri net-based workflows, motivate an extension to the original
tuplespace interface to facilitate efficient synchronization of control flow,
and highlight its benefits by providing quantitative and qualitative
evaluations of an application using the traditional tuplespace interface versus
an application using our extension.},
