所有网格项目都必须处理拓扑和操作信息，如资源分布、联系人列表和停机时间声明。正确地存储、维护和发布这些信息是成功的网格操作的关键要素之一。EGEE和WLCG项目采用的解决方案是一个中央存储库，它托管这些信息并使其可供用户和客户端工具使用。这一资料库称为GOCDB，通过EGEE和WLCG作为业务、监测、核算和报告的权威性主要信息来源。在给出了简短的历史GOCDB，本文介绍了目前的架构的工具，并给出了一个概述其完善的开发工作流程和发布程序。它还介绍了与其他EGEE操作工具的不同协作用例，并处理了为解决故障转移和复制问题而设置的高可用性机制。它描述了正在进行的工作，提供Web服务接口，并给出了与其他网格项目，如在英国的NGS集成的例子。本文最后提出了我们的愿景，GOCDB的未来和相关计划的基础上的伪对象数据库模型的架构，允许其分布在11个EGEE地区。这将是EGEE第三阶段最具挑战性的工作之一，为可持续的欧洲电网基础设施做准备。
All grid projects have to deal with topology and operational information like resource distribution, contact lists and downtime declarations. Storing, maintaining and publishing this information properly is one of the key elements to successful grid operations. The solution adopted by EGEE and WLCG projects is a central repository that hosts this information and makes it available to users and client tools. This repository, known as GOCDB, is used through EGEE and WLCG as an authoritative primary source of information for operations, monitoring, accounting and reporting. After giving a short history of GOCDB, the paper describes the current architecture of the tool and gives an overview of its well established development workflows and release procedures. It also presents different collaboration use cases with other EGEE operations tools and deals with the High Availability mechanism put in place to address failover and replication issues. It describes ongoing work on providing web services interfaces and gives examples of integration with other grid projects, such as the NGS in the UK. The paper finally presents our vision of GOCDB's future and associated plans to base its architecture on a pseudo object database model, allowing for its distribution across the 11 EGEE regions. This will be one of the most challenging works to achieve during the third phase of EGEE in order to prepare for a sustainable European Grid Infrastructure.
