Science Gateways and portals are Web-based user interface and accessibility tools that provide user-centric views of cyberinfrastructure: they convert computing resources into tools for Web-based science and education. Although numerous production gateways have been developed, problems remain. How can operational gateways sustain themselves as underlying resources and middleware change? How can a gateway leverage modern commercial Web techniques like gadgets and social networking? How can a gateway wrap complicated science applications as robust services and workflows that really work in day-to-day operation? Can startup gateways reuse proven software from mature gateways and avoid reinvention? The research team addresses these problems through the Open Gateways Computing Environments (OGCE) collaboration, an integrated group of software developers and operational gateway providers. Key partner gateways include GridChem, GISolve/SimpleGrid, the Purdue Scientific Data and CCSM Gateways, UltraScan, and MyOSG. The goal of investigators is to provide high-quality implementations of software tools for Grid and Cloud-based scientific application management, workflow composition and enactment, and social network-capable gadget component management. The assembled team supports the full lifecycle of gateway software, from requirements gathering to operational use. This cycle is directly reflected in the project's structure. Feature requests, enhancements, and changes to the software are managed using the Apache meritocracy model. The team achieves long-term sustainability through participation in the Apache Software Foundation. Software developed by the researchers complies with relevant standards: scientific job management is provided through Web services generated by an application factory service; workflows are executed using open standards for enactment engines, and user interface components are compatible with the Open Social specification. Additionally the team investigates the extension of gadget components to the HUBzero framework.

科学门户和门户是基于Web的用户界面和访问工具，提供以用户为中心的网络基础设施视图：它们将计算资源转换为基于Web的科学和教育工具。虽然已经开发了许多生产网关，但问题仍然存在。随着底层资源和中间件的变化，运营网关如何维持自身？门户如何利用现代商业Web技术，如小工具和社交网络？网关如何将复杂的科学应用程序包装成真正在日常运营中工作的强大服务和工作流？创业网关能否重复使用成熟网关中经过验证的软件并避免重新发明？研究小组通过开放网关计算环境(OGCE)协作解决这些问题，OGCE是一个由软件开发人员和运营网关提供商组成的集成组。主要的合作伙伴网关包括GridChem、GISolve/SimpleGrid、普渡科学数据和CCSM网关、超级市场和MyOSG。研究人员的目标是为基于网格和云的科学应用管理、工作流合成和执行以及支持社交网络的小工具组件管理提供高质量的软件工具实施。组建的团队支持网关软件的整个生命周期，从需求收集到运营使用。这种循环直接反映在项目的结构中。对软件的功能请求、增强和更改使用Apache精英管理模型进行管理。该团队通过参与阿帕奇软件基金会实现了长期可持续性。研究人员开发的软件符合相关标准：科学的作业管理通过应用程序工厂服务生成的Web服务提供；工作流使用开放标准执行，用于执行引擎；用户界面组件与开放社会规范兼容。此外，该团队还调查了Gadget组件对HUBzero框架的扩展。
