This proposal is designed to facilitate grid portal development using the portlet/container approach to building portals. This approach separates portal control and basic services from content. A central control server provides basic portal services such as authentication, access control, and user customizability. Into this framework, portal content and custom services are plugged in using software components called portlets. The container manages the organization and interaction of the portlets, and the portlets deliver specific web content (either local or remote), including Grid service interfaces.The portlet-based design concept supports distributed, loosely coupled development and deployment: user interfaces and science interface components can be developed independently, using the standard portlet API, and then reused between portals. Services and interfaces may be installed and added to various portals in a well-defined way. The portlet model is also an ideal fit to the emerging Open Grid Services Architecture (OGSA) and its implementation specification, the Open Grid Service Infrastructure (OGSI). Because OGSI is based on the new web-service standards, each Grid service can be directly accessed by a custom portlet. The impact of making the Grid readily approachable by the international community of researchers is potentially extremely large, as the immense resources that have been collected and organized in recent years by the underlying Grid technologies become visible as usable components of the global research community's desktop. This project will greatly simplify the use of Grid technologies and allow new services to be made readily available to individual researchers and groups by enabling the proliferation of Grid portal technology through reusability and simplification of installation. Scientists will be able to easily form flexible groups with collaborators across the world and use the Grid to share data and resources. This project provides tools for collaboration between established and ad hoc groups of users, enabling those scientists to communicate effectively with each other about the science they are doing, and providing customized views of the Grid that are tailored to meet the needs of collaborating groups.

该提案旨在促进使用portlet/容器方法构建门户的网格门户开发。这种方法将门户控制和基本服务与内容分开。中央控制服务器提供基本的门户服务，如身份验证、访问控制和用户可定制性。在这个框架中，门户内容和定制服务是使用称为portlet的软件组件插入的。容器管理portlet的组织和交互，portlet提供特定的Web内容(本地或远程)，包括网格服务接口。基于portlet的设计概念支持分布式、松散耦合的开发和部署：用户界面和科学界面组件可以使用标准的portlet API独立开发，然后在门户之间重用。可以以明确定义的方式安装服务和接口并将其添加到各种门户。Portlet模型也非常适合新兴的开放网格服务体系结构(OGSA)及其实现规范--开放网格服务基础设施(OGSI)。因为OGSI是基于新的Web服务标准的，所以每个网格服务都可以由一个定制的portlet直接访问。使国际研究人员易于接近网格的影响可能是非常大的，因为近年来由底层网格技术收集和组织的大量资源成为全球研究社区桌面的可用组件。该项目将极大地简化网格技术的使用，并通过可重复使用和简化安装使网格门户技术得以扩散，从而使新的服务容易提供给个人研究人员和团体。科学家将能够轻松地与世界各地的合作者组成灵活的小组，并使用网格来共享数据和资源。该项目为已建立的用户组和特设用户组之间的协作提供了工具，使这些科学家能够就他们正在做的科学有效地相互交流，并提供定制的网格视图，以满足协作小组的需求。
