REMO: A RGPS-based requirements modeling process for service oriented Architecture

Service oriented requirements engineering (SORE) is a main topic in service oriented development, which aims to capture stakeholders´ service oriented requirements in a proper specification. In this paper, we proposed a novel process for service oriented requirements modeling. Methodologies in the process enable to establish a layered requirements model from the perspectives of Role, Goal, Process, and Service. Different from other existing requirements engineering processes, our work focuses on modeling requirements from early requirements elicitation phrase. And then, the process can be used in a network and distributed environment to capture stakeholders´ need dynamically. In addition, layered requirements modeling process enables explicit requirements modeling from role, goal, process, and service facet. Last but not least, OWL and OWL-S described requirements model contains a wealth of semantic, which enables the model crucial to both human and machine-to-machine communication.
