Traditional workflow systems focus on providing support for the control-flow perspective of a business process, with other aspects such as data management and work distribution receiving markedly less attention. A guide to desirable workflow characteristics is provided by the well-known workflow patterns which are derived from a comprehensive survey of contemporary tools and modelling formalism...

Model-Driven Engineering holds the promise of transforming business models into code automatically. This requires the concept of model transformation. In this paper, we assess the feasibility of model transformations from Event-driven Process Chain models to Business Process Execution Language specifications. To this purpose, we use a framework based on ontological analysis and workflow pattern...

XML Process Definition Language (XPDL) is the language proposed by the Workflow Management Coalition (WfMC) to interchange process definitions between different workflow products. The goal of XPDL is to provide a Lingua Franca for the workflow domain allowing for the import and export process definitions between a variety of tools ranging from workflow management systems to modeling and simulat...

Scientific Workflow management systems have been largely adopted by data-intensive science communities. Many efforts have been dedicated to the representation and exploitation of provenance to improve reproducibility in data-intensive sciences. However, few works address the mining of provenance graphs to annotate the produced data with domain-specific context for better interpretation and shar...

TheWeb Service Choreography Description Language (WS-CDL) has been put forward as language for capturing sets of web service interactions and their control and data dependencies, seen from a global perspective. However the suitability of WS-CDL for this purpose has not been assessed in a systematic manner. This paper presents such an assessment by adopting a two-pronged approach. First, the pap...

The emergence of workflowmanagement systems offers supports for composing, coordinating and monitoring the execution of human tasks and component services. One of the key challenges is to provide a formal semantics and the facility to model, analyse and reason about workflow processes at both orchestration and choreography levels. This paper describes the formalisation of van der Aalst et al.’s...

The numbers of files in file systems have increased dramatically in recent years. Office workers spend much time and effort searching for the documents required for their jobs. To reduce these costs, we propose a new method for recommending files and operations on them. Existing technologies for recommendation, such as collaborative filtering, suffer from two problems. First, they can only work...

This chapter presents an agent-based architecture for integrating organizational knowledge repositories and business processes orchestrated by a workflow management system. This architecture proactively provides relevant knowledge to workflow tasks considering their context, and stores the information generated by its execution for future requirements. It describes components of the architectur...

The 20 workflow patterns proposed by Van der Aalst et al. provide a comprehensive benchmark for comparing control flow aspects of process modelling languages. In this paper, we present a novel class of Event-Driven Process Chains (EPCs) that is able to capture all of these patterns. This class is called “yet another” EPC as a tribute to YAWL that inspired this research. yEPCs extend EPCs by the...

SEPTEMBER 2004 183 In the last decade, about 370,000 acres (150,000 ha) of economically marginal farmland in the Lower Mississippi Alluvial Valley (LMAV) have been restored to bottomland hardwood forests (Stanturf and others 1998, King and Keeland 1999, Schoenholtz and others 2001). Planting of this considerable acreage is due to several federal programs, such as the Wetlands Reserve Program (W...
