The proposal plans to develop middleware that will allow individuals or groups using differing collaboration infrastructures to participate in an Access Grid-based session without the need for human intervention. This will be done by developing a web services model that will allow components to be updated as they become available without requiring the whole framework to be reworded. The proposal will develop three new modules:1. Network Services Engine which acts as the principal point of contact between the users and resolution engine2. Resolution Engine which matches user capabilities to the services available; it will also function as a Service Registry and,3. Network Services User Interface which provides the user's view into the network services framework.The work will build on the extensive expereince base of the Access Grid developers.These modules will enable users to maximize their use of the Access Grid. The Network Services User Interface funnels user requests for resources to the Network Services Registry, and the Resolution Engine uses the Network Services Interface to interact with the user in the event that manual resolution tasks need to be performed. The work will be beneficial to the collaboration community beyond that of the Access Grid. The proposal also includes technical guidance, training and evaluation of the Access Grid space and advice on changes and improvements at University of Chicago and the NSF Access nodes.

该提案计划开发中间件，允许使用不同协作基础设施的个人或团体参与基于Access Grid的会话，而无需人工干预。 这将通过开发一个网络服务模型来实现，该模型将允许组件在可用时进行更新，而不需要重新编写整个框架。 该提案将开发三个新模块：1。 网络服务引擎，作为用户和解析引擎之间的主要联系点2。 解析引擎，它将用户的能力与可用的服务相匹配;它也将作为服务注册表和3。 网络服务用户界面，提供了用户对网络服务框架的看法。这项工作将建立在Access Grid开发人员广泛的经验基础上。这些模块将使用户能够最大限度地利用Access Grid。 网络服务用户界面将用户的资源请求汇集到网络服务注册表，如果需要执行手动解析任务，解析引擎将使用网络服务界面与用户交互。 这项工作将有利于超越访问网格的协作社区。 该提案还包括访问网格空间的技术指导、培训和评估，以及关于芝加哥大学和NSF访问节点的更改和改进的建议。
