Automated Generation of BPEL Adapters

by Antonio Brogi, Razvan Popescu - In Proc. of ICSOC’06, volume 4294 of LNCS , 2006
"... Abstract. The heterogeneous, dynamic, distributed, and evolving nature of Web services calls for adaptation techniques to overcome various types of mismatches that may occur among services developed by different parties. In this paper we present a methodology for the automated generation of (service ..."

of (service) adapters capable of solving behavioural mismatches among BPEL processes. The adaptation process, given two communicating BPEL processes whose interaction may lock, builds (if possible) a BPEL process that allows the two processes to successfully interoperate. A key ingredient of the adaptation

Experience with Adapting a WS-BPEL Runtime for eScience Workflows

by Thilina Gunarathne, Chathura Herath, Eran Chinthaka, Suresh Marru
"... Scientists believe in the concept of collective intelligence and are increasingly collaborating with their peers, sharing data and simulation techniques. These collaborations are made possible by building eScience infrastructures. eScience infrastructures build and assemble various scientific workfl ..."

Mayflower -- Explorative Modeling of Scientific Workflows with BPEL

by Mirko Sonntag, Michael Hahn, Dimka Karastoyanova , 2012
"... Using workflows for scientific calculations, experiments and simulations has been a success story in many cases. Unfortunately, most of the existing scientific workflow systems implement proprietary, non-standardized workflow languages, not taking advantage of the achievements of the conventional ..."

From BPEL Processes to YAWL Workflows

by Antonio Brogi, Razvan Popescu - In Proceedings of the 3rd International Workshop on Web Services and Formal Methods (WS-FM’2006 , 2006
"... Abstract. BPEL is currently the most widespread language for composing Web services, but it lacks formal semantics. YAWL is a workflow language with a well defined formal semantics that implements the most common workflow patterns. In this paper we provide a methodology for translating BPEL processe ..."

processes into YAWL workflows, thus paving the way for the formal analysis, aggregation and adaptation of BPEL processes. The approach we propose defines a YAWL pattern for each BPEL activity. The translation of a BPEL process reduces then to suitably instantiating and interconnecting the patterns of its

A Workflow Management Platform for Media Analysis in BPEL-based Grid Environments

by Benjamin Ihle, Sebastian Kirch, Ernst Juhnke, Dominik Seiler, Bernd Freisleben
"... Motivation: In many media applications, there is a need to index very large amounts of audiovisual content in a minimum of time. Due to their scalability, Grid infrastructures are well suited for processing a large number of media files. Within the BMBF1-funded research project MediaGrid2, a distrib ..."
Abstract - Add to MetaCart
distributed media analysis platform is currently being developed. It enables its users to analyze and index large quantities of multimedia data within a short amount of time. Grid services as distributed processing units and BPEL4Grid [10] as a scientific BPEL3-based workflow system are the foundations

BPEL2YAWL: Translating BPEL processes into YAWL workflows

by Antonio Brogi, Razvan Popescu , 2006
"... The availability of different languages for the description of Web service behaviour hinders automated Web service aggregation, discovery, and adaptation, as currently there are no available tools for the automated translation of service protocols. In this paper we motivate the choice of YAWL as a l ..."

Furthermore, we provide the specification of a translator of BPEL processes into YAWL workflows, thus paving the way for the formal analysis, aggregation, discovery, and adaptation of BPEL processes. In short, the specification defines a

We choose BPEL and Taverna as candidate solutions, and compare their usability in the full lifecycle of a scientific workflow, including service discovery, service composition, workflow execution, and workflow result analysis. We determine that BPEL offers a comprehensive set of primitives
