Digital Libraries: From Process Modelling to Grid-based Service Oriented Architecture

摘要

Graphical Business Process Modelling Languages (BPML) like Role ActivityDiagrams (RAD) provide ease and flexibility for modelling business behaviour.However, these languages show limited applicability in terms of enactment overdistributed systems paradigms like Service Oriented Architecture (SOA) basedgrid computing. This paper investigates RAD modelling of a ScientificPublishing Process (SPP) for Digital Libraries (DL) and tries to determine thesuitability of Pi-Calculus based formal approaches to enact SOA based gridcomputing. In order to achieve this purpose, the Pi-Calculus based formaltransformation from a RAD model of SPP for DL draws attention towards a numberof challenging issues including issues that require particular designconsiderations for appropriate enactment in a SOA based grid system.
