abstract = {In this work we propose an approach for verifying privace timed-related
prroperties of web service protocols. While in our previous work the addressed
problem in business protocols is focused on the analysis and management of
functional requirements that support rich timing constraints, our approach
extends the previous results to capture the timed behavior of privacy
constraints. Hence, we provide a model called Timed Private Business Protocol
TPBP. Next, we emphasize the timed properties related to privacy in TPBP.
Finally, we present the different types of timed property verification to
achieve upon the timed private business protocol.},

found in current Web service transports: asynchronism, strong decoupling of
sender and receiver and support for advanced message exchange patterns, such as
one-to-many interactions, directly on the transport level. We describe the

operations provided by the tuplespace interface to realize certain Web service

abstract = {Software as a Service (SaaS) is a new delivery model for software. Software in
a SaaS model is no longer run exclusively for one customer at a customer’s
premise but run at a service provider and accessed via the Internet. A provider
of Software as a Service exploits economies of scale by hosting and providing
the same application for several different customers. However, each individual
customer has different requirements for the same basic application. In order to
allow each customer to customize the process layer and related artifacts of a
SaaS application to their specific needs the application needs to provide a set
of variability points that can be modified by customers. In this paper we
describe the notion of a variability descriptor that defines variability points
for the process layer and related artifacts of process-based, service-oriented
SaaS applications. Furthermore we describe how these variability descriptors
can be transformed into a WS-BPEL process model that can then be used to guide
a customer through the customization of the SaaS application.},

mechanism to define an operation by means of message exchange patterns (MEPs).
In this paper we identify new MEPs and extend the template used to define MEPs
to allow expressing more complex patterns. Furthermore, we compare the
expressivity of MEPs in general with other work and formalisms in the field of
service interaction. We give a refined definition of MEPs based on a detailed
discussion and discuss how WSDL and the MEPs in particular can be combined with
the choreography approach.},

solution eliminating the presumed complexity of the WS-* standards may be in
sight: advocates of REpresentational State Transfer (REST) have come to believe
that their ideas explaining why the World Wide Web works are just as applicable
to solve enterprise application integration problems and to simplify the
plumbing required to build service-oriented architectures. In this paper we
objectify the WS-* vs. REST debate by giving a quantitative technical
comparison based on architectural principles and decisions. We show that the
two approaches differ in the number of architectural decisions that must be
made and in the number of available alternatives. This discrepancy between
freedom-from-choice and freedom-of-choice explains the complexity difference
perceived. However, we also show that there are significant differences in the
consequences of certain decisions in terms of resulting development and
maintenance costs. Our comparison helps technical decision makers to assess the
two integration styles and technologies more objectively and select the one
that best fits their needs: REST is well suited for basic, ad hoc integration
scenarios, WS-* is more flexible and addresses advanced quality of service
requirements commonly occurring in enterprise computing.},

two kinds of BPEL processes that are defined in the BPEL standard. An abstract

executable through ``executable completion''. The BPEL standard defines a set of
rules that must be obeyed during such an executable completion. In this paper,
we present an algorithm for validating whether an executable BPEL process is a
valid executable completion of an abstract BPEL process. Our approach advances
the existing XML comparison algorithms in a way that it takes the BPEL-specific

``executable completion'' of abstract BPEL processes.},

BPEL — without requiring any new middleware for the case of flat flows. The
solution also supports splitting loops and scopes that have compensation and/or
fault handlers. When splitting loops and scopes, we extend existing Web
services standards and frameworks in a standard compliant manner in order to
support the resulting split control (not data) between the fragments. Data
dependencies, however, are handled directly using BPEL constructs placed in the
fragments even for split loops and scopes.
We present a solution that uses a BPEL process, partition information, and
results of data-flow analysis to produce a BPEL process for each participant.
The collective behavior of these participant processes recreates the control
and data flow of the non-split process. Previous work presented process
splitting using a variant of BPEL where data flow is modeled explicitly using
``data links''. We reuse the control flow aspect from that work as well as the
control flow aspect from our work on splitting loops and scopes, focusing in
this paper on maintaining the data dependencies in standard BPEL.},
