CSR-AES: Orpheus: Content and Service Composition Framework for Cooperative Grid Computing

该项目将开发一个名为Orpheus的内容和服务组合体系结构，它将表现为一个用于协作网格计算的覆盖沙漏服务基础设施。为了解决沙漏Orpheus的挑战，该项目涉及四个主要研究目标：(A)来自具有相似兴趣的用户/组的复合内容请求的规范，(B)沙漏服务基础设施的构建，(C)分布式生产和传播服务和政策，以及(D)根据显示能力显示定制复合内容的多视角呈现系统。沙漏服务基础设施是一种新颖的解决方案，它将在高级执行系统中提供全新的可能性。协作网格计算非常需要这样的解决方案，因为现有的解决方案不能提供灵活的、定制的分布式合成和基于用户/组兴趣/分数的不同内容类型的交付。许多分布式资源可以通过互联网访问，对于网格和其他社区来说，以一种考虑到用户组偏好的方式访问这些资源将是有利的。沙漏服务基础设施代表着突破性的解决方案和重大的计算机科学进步，它将整合服务计算、服务多播、多视点呈现系统和内容信息管理，以支持自治、分布式和动态内容制作和交付等复杂的分布式系统。

The project will develop a Content and Service Composition Architecture, called Orpheus, which will manifest itself as an overlay hourglass service infrastructure for cooperative grid computing. To solve the challenges of the hourglass Orpheus, the project involves four major research goals: (a) specification of composite content request from a user/group with similar interests, (b) construction of the hourglass service infrastructure, (c) distributed production and dissemination services and policies, and (d) multi-view presentation systems to display customized composite content according to display capabilities. The hourglass service infrastructure is a novel solution that will provide fundamentally new possibilities in Advanced Execution Systems. The cooperative grid computing is in great need of such a solution as current solutions do not offer flexible, customized distributed composition and delivery of different content types based on user/group interest/scores. Many distributed sources are accessible via the Internet and it would be advantageous for grid and other communities to get access to these sources in such a way that user group preferences are taken into account. The hourglass service infrastructure represents a breakthrough solution and significant computer science advances that will integrate service computing, QoSaware service multicasting, multi-view presentation systems and content information management to support complex distributed systems such as autonomous, distributed and dynamic content production and delivery.
