Data-Aware Service Choreographies Through Transparent Data Exchange [chapter]

Michael Hahn, Dimka Karastoyanova, Frank Leymann
2016 Lecture Notes in Computer Science  
Our focus in this paper is on enabling the decoupling of data flow, data exchange and management from the control flow in service compositions and choreographies through novel middleware abstractions and  ...  This allows us to perform the data flow of choreographies in a peer-to-peer fashion decoupled from their control flow.  ...  Acknowledgment The authors would like to thank the German Research Foundation (DFG) for financial support of the project within the Cluster of Excellence in Simulation Technology (EXC 310/2) at the University  ...

Semantic Web Services Grounding

J. Kopecky, D. Roman, M. Moran, D. Fensel
2006 Advanced Int'l Conference on Telecommunications and Int'l Conference on Internet and Web Applications and Services (AICT-ICIW'06)  
Semantic Web Services frameworks like OWL-S and WSMO combine semantic descriptions of Web service capabilities, inputs, outputs and behavior with the syntactic interface descriptions in WSDL and XML Schema  ...  In this paper we identify the uses for grounding and we present the existing grounding approaches and propose new ones, discussing their respective advantages and drawbacks.  ...  The authors are involved in WSMO grounding effort, and will focus their future work on extending WSMO with the various approaches, especially for data grounding.  ...

Artifact-Centric Choreographies [chapter]

Niels Lohmann, Karsten Wolf
2010 Lecture Notes in Computer Science  
Classical notations for service collaborations focus either on the control flow of participating services (interacting models) or the order in which messages are exchanged (interaction models).  ...  In contrast, artifact-centric models pursue the converse strategy and begin with a specification of data objects.  ...  To this end, the choreography is transformed into a service where the local processes are computed as correctly interacting partners, cf. Fig. 8 .  ...

defined BPEL4Chor choreographies and presents how to carry out this transformation.  ...  To achieve applicability of BPEL in the choreography space, we defined BPEL4Chor as choreography extensions for BPEL in previous work.  ...  The extended XPDL format is used as input for the transformation web service. We introduced participant reference data objects to reflect participant references in BPMN.  ...

View-based interorganizational workflows

Johann Eder, Nico Kerschbaumer, Julius Köpke, Horst Pichler, Amirreza Tahamtan
2011 Proceedings of the 12th International Conference on Computer Systems and Technologies - CompSysTech '11  
We propose a new architecture for modeling and enacting of interorganizational business processes which captures both control flow and data flow aspects of web service orchestrations and choreographies  ...  To cope with interoperability problems that arise from different data formats and internal schemas used by different choreography participants we support transformation of XML-based data types through  ...  A missing piece in the modeling phase is the consideration of data aspects, like the specification of data structures (schemas) and message transformations between different schemas.  ...

Integrating Quality of Service Aspects in Top-Down Business Process Development Using WS-CDL and WS-BPEL

Florian Rosenberg, Christian Enzi, Anton Michlmayr, Christian Platzer, Schahram Dustdar
2007 International Enterprise Distributed Object Computing Conference, Proceedings  
The partners have to agree on a common data format and meaning as well as on the Quality of Service (QoS) requirements each partner has to fulfill.  ...  A choreography does not describe any internal actions that occur within a participating service, such as internal computation or data transformation, but rather focuses on the observable public exchange  ...  This is achieved by transforming the models from the choreography layer to executable code in the orchestration layer as depicted in Figure 2 .  ...

Automatic skeleton generation for data-aware service choreographies

Huu Nghia Nguyen, Pascal Poizat, Fatiha Zaidi
2013 2013 IEEE 24th International Symposium on Software Reliability Engineering (ISSRE)  
In this paper, we support a reliable data-aware service choreography development process through a dedicated projection.  ...  The projection is also valuable in a bottom-up approach, where the skeletons can act as controllers between reused services in order to enforce the respect of the choreography.  ...  It includes a data-aware choreography language that we have defined, and a transformation from this language to our choreography model.  ...

A Requirements-Led Approach for Specifying QoS-Aware Service Choreographies: An Experience Report [chapter]

Neil Maiden, James Lockerbie, Konstantinos Zachos, Antonia Bertolino, Guglielmo De Angelis, Francesca Lonetti
2014 Lecture Notes in Computer Science  
[Question/problem] We developed a requirements-led approach that aims to provide tools and processes to transform requirements expressed on service-based systems to QoS-aware choreography specifications  ...  [Context and motivation] Choreographies are a form of service composition in which partner services interact in a global scenario without a single point of control.  ...  Quality of Service (QoS) has been acknowledged as a main concern in service-oriented computing (SOC) and in QoS-aware service composition.  ...
