AstroGrid3; Bristol component

到2007年底，AstroGrid项目将完成虚拟观测站系统运行所需的所有核心基础设施软件组件的开发，并将具备建立和运行原型工作系统的经验。使用AstroGrid软件产品和关键数据中心工作人员的技能，我们建议为英国天文学家构建一个全面运作和可持续的VO服务。这将涉及几个方面的工作。(i)在每个数据中心站点设置核心VO服务-注册表、作业执行服务、MySpace和社区身份验证。(ii)根据虚拟组织标准和虚拟组织接口，发布商定的特定主要数据服务和应用程序清单。(iii)与天文学界合作，优化关键任务的科学回报，使用VO -包括用户指南，帮助台和培训研讨会。(iv)与英国所有部门的系统管理员和工具编写人员合作，提供培训研讨会，他们希望部署的任何组件的自动化和可靠的自动安装版本，以及任何语言的工具与VO服务交互的简单方法。(v)根据工程标准维护和升级核心软件产品。新的功能将被添加，重新设计将是必要的，因为从IVOA和其他电子科学世界的成熟出现的标准。(vi)跟上不断变化的技术环境，评估新技术并构建可能的新基础设施组件的原型。该服务将为英国所有天文学家提供服务，但其交付集中在少数几个关键中心。该联盟由参与构建AstroGrid产品的机构组成，这些机构密切参与了未来十年预计的几乎所有关键数据库的交付-例如XMM，WFCAM，VISTA，SDO，Planck，GAIA，阿尔马，e-MERLIN和WFMOS。确保这些数据库可通过志愿人员组织接口使用是本项目的主要目标。在建设这些设施或飞行任务方面都进行了巨大的投资，而且已经或即将对这些飞行任务的基础数据管理进行大量投资-数据的输送和存档。将所有这些数据集集成到虚拟组织基础设施中，并建立和运行核心虚拟组织服务，如数据发现、工作流、社区存储、单点登录和工具互操作性，将以相对较少的资金大大提高科学水平。大部分成本是安装、维护和改进服务所需的员工，以及用于运行核心服务和改进网络的少量硬件投资。

By the end of 2007, the AstroGrid project will have completed development of all the core infrastructure software components needed for an operational Virtual Observatory (VO) system, and will have had experience setting up and running a prototype working system. Using both the AstroGrid software product, and the skills of key data centre staff, we propose to construct a fully operational and sustainable VO service for UK astronomers. This will involve several areas of work. (i) Setting up core VO services at each data centre site - Registry, Job Execution Service, MySpace, and Community Authentication. (ii) Publishing an agreed list of specific prime data services and applications, to VO standards and with VO interfaces. (iii) Working with the astronomy community to optimise science return from key missions, using the VO - including user guides, helpdesk, and training workshops. (iv) Working with system administrators and tools writers across all UK departments, providing training workshops, automated and reliable auto-install versions of any components that they wish to deploy, and easy methods for tools in any language to interact with VO services. (v) Maintaining and upgrading the core software product to engineering standards. New functionality will be added, and re-engineering will be necessary as the standards emerging from the IVOA and the rest of the e-Science world mature. (vi) Keeping abreast of the changing technology landscape, assessing new technologies and constructing prototypes of possible new infrastructure components. The service will be run for the benefit of all astronomers in the UK, but its delivery is centred on a handful of key centres. The consortium consists of institutions which were involved in constructing the AstroGrid product, and which are closely involved in the delivery in just about all of the key databases expected over the next decade - such as XMM, WFCAM, VISTA, SDO, Planck, GAIA, ALMA, e-MERLIN, and WFMOS. Ensuring that these databases are available through VO interfaces is the main aim of this project. Huge investment has been made in building each of these facilities or missions, and substantial investment has been or will soon be made in the basis data management for these missions - pipelining and archiving the data. Integrating all these datasets into the VO infrastructure, and setting up and operating core VO services such as data discovery, workflow, community storage, single sign on, and tool interoperability, will add substantially improved science for relatively little money. Most of the cost is in the staff required to install, maintain, and improve services, with a small hardware investment for running core services and improved networking.
