Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
Requirements modeling has been recently introduced in the UML world with the form of a new profile called SysML. This paper explores the possibility to link concepts used to describe requirements with those of the enterprise language of RM-ODP. Some correspondence rules are proposed and illustrated on a case study.
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
Accelerated by the rapid deployment of distributed systems and the Internet, online collaboration and information sharing are pervasive in enterprise computing environment. With regard to the requirements of online collaboration and information sharing, authentication information needs flexible manipulation to facilitate federation across trust domains. To achieve identity federation for federated...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
In this paper we discuss the use cases for monitoring of Web services for compliance with policies and service level agreements. In particular, the quality of service associated with Web service interactions and its monitoring rely on the proper use by both parties of related Web service protocols. This monitoring is best served by an event-centric model and an extensible scripting language, such...
Information privacy typically concerns the confidentiality of personal identifiable information (PII) and protected health information (PHI) such as electronic medical records. Thus, the information access control mechanism for e-health services must be embedded with privacy-enhancing technologies. Role-based access control (RBAC) model has been widely investigated and applied to various applications...
