EarthCube IA: Collaborative Proposal: Cross-Domain Observational Metadata Environmental Sensing Network (X-DOMES)

跨越领域、机构和政治边界，我们的环境正在被持续观察和研究。该项目的研究人员正在寻找短期、近期和长期的变化，同时研究新的和不断发展的方法来观察属性并处理收集到的观察结果。新兴技术使我们能够公开和自由地提供和发现数据。但是，如果我们不理解新发现的数据及其固有的局限性和偏见，就不能负责任地将其用于新的或合作的研究工作。X-穹顶项目将与环境传感器制造商和研究人员合作，开发工具以及社会和技术基础设施，以促进创建有关数据的数据(元数据)。元数据不仅描述观察的对象、时间和地点，还必须记录观察是如何产生的(出处)。通过将这些知识从手册和人类可读的文档中提取出来，X圆顶模型创建了可以被视为数据的元数据？可发现和可搜索，使其可以整合到自动归档和处理中，以实现质量保证和验证方法。利用与美国国家科学基金会资助的大型数据管理项目、EarthCube构建块和工作组以及环境传感器制造商和联盟的现有关系，我们将建立一个传感器制造商和其他利益相关者社区，为描述跨地球科学领域的传感器和观测提供统一的方法。X-DOMES试点项目建立在现有传感器元数据模型的基础上，引用注册的、基于标准的词汇表，将提供一套工具，基于开放地理空间联盟(OGC)和万维网联盟(W3C)社区采用的标准，以演示和促进可在线和/或直接从机载传感器描述发现和访问的文档的生成。该项目还将展示通过基于标准的网络服务将数据与元数据相关联的机制。随着供应商准备好的工具在基础广泛的社区中实施，X-DOMES网络将为开发和采用可互操作的访问急需的内容丰富的传感器元数据奠定基础。

Across-domains, agencies and political boundaries, our environment is being continuously observed and studied. The researchers in this project are looking for short-term, near-term and long-term changes while researching new and evolving methods to observe properties and to process the collected observations. Emerging technologies enable us to provide and discover the data openly and freely. But, if we do not understand the newly discovered data, with its inherent limitations and biases, it cannot be responsibly utilized for new or collaborative research efforts. Working with environmental sensor manufacturers and researchers, the X-DOMES project will develop tools and social and technical infrastructure to facilitate the creation of data about data (metadata). Metadata describes not only who, when and where the observations were made, but also it must document how an observation came to be (provenance). By taking this knowledge out of manuals and human-readable documents, the X-DOMES model creates metadata that can be treated like data ? discoverable and searchable, making it ready to be incorporated into automated archival and processing for quality assurance and validation methods. Leveraging existing relationships with large NSF-funded data management programs, EarthCube building blocks and working groups, and environmental sensor manufacturers and consortia, we will establish a community of sensor manufacturers and other stakeholders to provide a unifying approach to describing sensors and observations across geo-science domains. Built on an existing sensor metadata model that references registered, standards-based vocabularies, the X-DOMES pilot project will provide a suite of tools, built upon community-adopted standards of the Open Geospatial Consortium (OGC) and World Wide Web Consortium (W3C) to demonstrate and facilitate the generation of documents that are discoverable and accessible on-line and/or directly from onboard sensor descriptions. The project will also demonstrate mechanisms to associate the data with the metadata through standards-based web services. With vendor-ready tools implemented throughout a broad-based community, the X-DOMES Network will lay the foundation for the development of and adoption of interoperable access to much needed content-rich sensor metadata.
