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.

该提案旨在使用Portlet/Container方法来促进网站开发的建筑门户网站。 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了基本的门户服务，例如身份验证，访问控制和用户自定义性。 在此框架中，使用称为Portlet的软件组件插入门户内容和自定义服务。 该容器管理Portlet的组织和交互，Portlet提供了特定的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，宽松耦合的开发和部署：用户界面和科学界面组件可以独立开发，可以使用标准Portlet API在Portals之间进行独立开发，然后再使用。可以以明确的方式安装服务和接口。 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，即开放网格服务基础结构（OGSI）。由于OGSI基于新的Web服务标准，因此可以通过自定义Portlet直接访问每个网格服务。 使网格易于接近国际研究人员社区的影响可能非常大，因为近年来，基础网格技术在全球研究社区桌面的可用组件中可见的巨大资源变得可见。 该项目将大大简化网格技术的使用，并通过可重复使用和简化安装来启用网格门户技术的扩散，从而使单个研究人员和小组轻松获得新服务。 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，并使用网格共享数据和资源。 该项目为建立和临时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进行有效的沟通，并提供量身定制的网格视图，这些视图是为了满足协作群体的需求。
