Ivo José Garcia dos Santos, Edmundo R. M. Madeira · I3E · 2004
Companies are daily trying to find new ways to cope with the increasing competitive pressures imposed by the global economy. Static and huge enterprises are being replaced by dynamic business networks where each participant offers to the others specialized services. Service-Oriented Computing (SOC) is being considered by many as a very interesting technological solution to the new B2B interactions introduced by this economical scenario. This paper presents a Virtual Marketplace infrastructure, called VM-Flow, which supports Dynamic Virtual Enterprises, is workflow-based and introduces a series of interaction policies that treat aspects like autonomy and privacy. Also, Service Composition is shown as a suitable solution to implement these policy-based interorganizational interactions. Some issues on the developed prototype are discussed and an application built over it is described.
