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.},

   abstract = {The SOAP messaging framework, as one key technology of the Web service technology standard stack, de nes a standardized message format for Web service interactions, a set of rules governing their processing and a mechanism that describes how SOAP messages can be transmitted over di erent network transport protocols, called SOAP bindings. The most prominent example for a Web service transport today, is the Hypertext Transfer Protocol (HTTP), which however su ers from certain drawbacks such as being inherently synchronous in nature and not providing decoupling of message sender and receiver in reference or time. In this paper, we present tuplespace technology as an alternative Web service transport that is characterized by a number of properties that are not 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 representation of SOAP messages in tuple form and exemplify how to use the operations provided by the tuplespace interface to realize certain Web service message exchange patterns.},

   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.},

In contrast to its predecessor (WSDL 1.1), WSDL 2.0 does not define a fixed set of operation types but provides for a generic 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.},

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 supporting concepts are pattern languages and architectural decision models. Unfortunately, both concepts only provide partial support: Extensive upfront education is needed for practitioners to be in command of the full pattern literature relevant in their field; retrospective architectural decision modeling is viewed as a painful extra responsibility without immediate gains. In this paper, we combine pattern languages and reusable architectural decision models into a design method that is both comprehensive and comprehensible. Our design method identifies the required decisions in requirements models systematically, gives domain-specific pattern selection advice, and provides traceability from platform-independent patterns to platform-specific decisions. We validate our approach by applying it to enterprise applications as an exemplary application genre and a SOA case study from the finance industry.},

Enterprise Application Integration Patterns help to address this challenge by describing recurring EAI problems and proposing possible solutions at an abstract level. However, EAI patterns are documentation only used by systems architects and developers to decide how to implement an integration solution. Thus, patterns do not specify how to produce the code that will actually implement the solution described by the pattern on a specific middleware. In this paper we introduce a framework that provides configuration capabilities for EAI patterns. The framework also allows to generate executable integration code from EAI patterns using a model-driven architecture approach. Furthermore, we present a tool providing this framework.},

Abstract and executable processes are two kinds of BPEL processes that are defined in the BPEL standard. An abstract process can be used as a process template, which can be completed and made 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 characteristics into account and is optimized towards the validation of ``executable completion'' of abstract BPEL processes.},

   abstract = {Continuous process improvement (CPI) may require a BPEL process to be split amongst different participants. In this paper, we enable splitting standard 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.},
