Abstract

STROPPI, Luis J.R.; VILLARREAL, Pablo D.  and  CHIOTTI, Omar. Architecture to Support the Resource Perspective of BPEL Processes. CLEIej [online]. 2013, vol.16, n.1, pp.4-4. ISSN 0717-5000.

This work proposes an extension to the WS-HumanTask architecture developed to provide support to the Resource Perspective of BPEL processes. The extension is aimed to overcome limitations identified in the support of BPEL4People and WS-HumanTask to recurrent Resource Perspective requirements described by the Workflow Resource Patterns and well known reference models of workflow management systems. These limitations have been identified through an assessment of BPEL4People and WS-HumanTask against a conceptual model enabling the representation of Resource Perspective requirements by defining three aspects: Resource Structure, Work Distribution and Authorization. The proposed extension specifies an autonomous People Directory component to be integrated with the Task Processor and the Task Client WS-HumanTask components. The behavior of the Task Processor and the Task Client is also extended in order to enable their interactions with the People Directory and to improve their support to the stated Resource Perspective aspects.

Keywords : BPEL4People; WS-HumanTask; Resource Perspective; Workflow.
