EarthCube Building Blocks: Collaborative Proposal: GeoLink - Leveraging Semantics and Linked Data for Data Sharing and Discovery in the Geosciences

提出的工作解决了EarthCube项目成功的核心挑战：如何利用最先进的技术进行地球科学数据的发现、访问和集成。该项目汇集了海洋、地球和极地科学领域的重要地球科学成果，展示了如何将创新技术强有力地应用于这些设施，以增强科学家发现和解释相关地球科学数据和知识的能力。最终产品GEOLink将降低跨存储库数据发现和访问的障碍，同时尊重和保留存储库的自主性和异构性。他们将通过一个门户演示该方法，该门户允许搜索和浏览来自多个存储库的集成内容。EarthCube面临的一个关键挑战是以可持续的方式实现数据发现、访问和集成。现有的数据储存库和网络必须联系起来，同时保持其独立的任务和服务与现有学科共同体的联系。文化、概念和基础设施的异质性必须得到尊重，以保持不同的观点和不同的优先事项，从而促进“地球立方”项目的包容性。特别是，需要以包容的方式尊重数据或存储库提供者的个人选择，而集成方法必须反映这一点。然而，与此同时，地球科学数据的多样性和异质性对其发现构成了重大障碍。在这个项目中，参与的研究人员将开发一个名为GEOLink的示范项目，其基础是：1)以“关联开放数据”的形式数字化发布地球科学数据和知识；结合2)使用联合存储库之间共享的设计模式和词汇表进行语义集成；3)在深度和广度上都可扩展的底层网络基础设施，可以成为EarthCube数据协调的中心构建块。该方法的网络基础设施是可扩展的、可持续的和负担得起的——利用了关联开放数据和形式化语义的最新发展，以共享的本体设计模式为基础。启用geolink的存储库将支持相关资源的发现，包括滚动甲板到存储库（R2R）、生物和化学海洋学数据管理办公室（BCO-DMO）、综合地球数据应用（IEDA）、长期生态研究网络（LTER）、DataONE和国际海洋发现计划（IODP），以及来自其他EarthCube构建块项目和合作者的内容。

The proposed work addresses a challenge central to the EarthCube program's success: How to employ state of the art technology for geoscience data discovery, access, and integration. The project brings together significant geosciences holdings in the ocean, earth and polar sciences to demonstrate how innovative technologies can be robustly applied to these facilities to enhance the capabilities for scientists to discover and interpret relevant geoscience data and knowledge. The end product, GEOLink, will lower barriers to cross-repository data discovery and access, while respecting and preserving repository autonomy and heterogeneity. They will demonstrate the approach through a portal that allows searching and browsing of integrated content from multiple repositories.A key challenge for EarthCube is to enable data discovery, access, and integration in a sustainable way. Existing data repositories and networks must be linked, while retaining their independent missions and services to existing disciplinary communities. Cultural, conceptual, and infrastructural heterogeneities must be respected in order to maintain different perspectives and differing priorities and thus foster inclusivity in the EarthCube endeavor. In particular, individual choices made by providers of data or repositories will need to be respected in an inclusive manner, and approaches to integration must reflect this. At the same time, however, the diversity and heterogeneity of geoscience data presents a significant barrier to its discovery. In this project, the researchers involved will develop a demonstration called GEOLink based on: 1) digital publication of geoscience data and knowledge as "Linked Open Data"; combined with 2) semantic integration using design patterns and vocabularies shared among federated repositories; and 3) an underlying cyberinfrastructure extendable in both depth and breadth, that can become a central building block for EarthCube data harmonization. The cyberinfrastructure underlying the approach is extendable, sustainable, and affordable - leveraging state of the art developments in Linked Open Data and formal semantics, grounded through shared Ontology Design Patterns. GEOLink-enabled repositories will support discovery of related resources, including Rolling Deck to Repository (R2R), the Biological and Chemical Oceanographic Data Management Office (BCO-DMO), Integrated Earth Data Applications (IEDA), the Long-Term Ecological Research Network (LTER), DataONE, and the International Ocean Discovery Program (IODP), as well content from other EarthCube Building Block projects and collaborators.
