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

这项拟议的工作解决了EarthCube计划成功的核心挑战：如何利用最先进的技术来发现、访问和集成地球科学数据。该项目汇集了海洋、地球和极地科学方面的大量地球科学知识，以展示如何将创新技术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门槛，同时尊重和保留存储库的自主性和异构性。他们将通过允许搜索和浏览来自多个存储库的集成内容的门户来演示该方法。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。必须将现有的数据储存库和网络连接起来，同时保留其独立的任务和为现有的纪律团体提供的服务。必须尊重文化、概念和基础设施的异质性，以保持不同的视角和不同的优先事项，从而促进地球立方努力的包容性。特别是，数据或储存库提供者的个人选择将需要以包容的方式得到尊重，整合的方法必须反映这一点。然而，与此同时，地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的演示，其基础是：1)将地球科学数据和知识以“链接的开放数据”的形式进行数字出版；2)使用设计模式和联邦储存库之间共享的词汇进行语义整合；3)一个可在深度和广度上扩展的底层网络基础设施，它可以成为协调EarthCube数据的核心构件。该方法背后的网络基础设施是可扩展的、可持续的和负担得起的-利用链接的开放数据和形式语义的最新发展，基于共享的本体设计模式。Geolink启用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积木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.
