DataONE initially emphasizes observational data collected by biological (genome to ecosystem) and environmental (atmospheric, ecological, hydrological, and oceanographic) scientists, research networks, and environmental observatories. DataONE will be domain agnostic, progressively expanding to broader domains and building on infrastructure and interoperability with DataNet partners.</p> <div class="figure" id="id1" style="width: 7in"> <img alt="../_images/proposal_figure_1.png" src="../_images/proposal_figure_1.png" /> <p class="caption"><span class="caption-text">DataONE Member Nodes form a robust, distributed network via coordinating services provided by a set of Coordinating Nodes (i.e., Oak Ridge Campus, UC-Santa Barbara, and University of New Mexico) arranged in a high-availability configuration. Scientists and citizens interact with Member Nodes (e.g., South African Environmental Observation Network, California Digital Library, USGS National Biological Information Infrastructure) through software tools that utilize standardized interfaces. This structure supports many different usage scenarios, such as data and metadata management and replication (e.g., using Morpho [black arrows] or the Mercury system [orange arrows]), as well as analysis and modeling (e.g., using commercial software like Matlab [light green arrows] and open-source scientific workflow systems like Kepler [blue arrows]). Coordinating Nodes perform many basic indexing and data replication services to ensure data availability and preservation (e.g., node registration [purple arrow] and monitoring via heartbeat services (red arrow]).</span></p> </div> </div> <div class="section" id="us-02-value-added-services-proposed"> <h2>US 02. Value Added Services (proposed)<a class="headerlink" href="#us-02-value-added-services-proposed" title="Permalink to this headline">¶</a></h2> <p>DataONE is not the end, but rather the means to enable scientists and citizens to address and better understand the difficult and complex biological, environmental, social, and technological challenges affecting human, ecosystem, and planetary sustainability. The comprehensive cyber-infrastructure allows novel questions to be asked that require harnessing the enormity of existing data and developing new methods to combine and analyze diverse data resources (see figure below).</p> <p>DataONE will accomplish its goals by making scientists, students, librarians, and citizens active participants in the data life cycle, especially the data preservation process. By supporting community derived interoperability standards and incorporating new value-added and innovative technologies (e.g., for semantic and geospatial information, scientific workflows, and advanced visualization) into the scientific process, DataONE will facilitate sophisticated data integration, analysis, interpretation, and understanding. A strong education and outreach program focuses on scientists and students learning to better and more easily manage, preserve, analyze, and visualize Earth observational data. Citizen scientists are actively engaged in data preservation and scientific discovery through their involvement in programs such as the USA National Phenology Network (USA-NPN) and numerous Cornell Laboratory of Ornithology citizen science efforts (e.g., eBird, Project FeederWatch).</p> <div class="figure" id="id2" style="width: 100%"> <img alt="../_images/proposal_figure_2.png" src="../_images/proposal_figure_2.png" /> <p class="caption"><span class="caption-text">DataONE value-added services enable scientists to address novel questions through integrating disparate data sources (top), supporting geospatial data processing (lower left), and providing scientific workflow solutions like Kepler (lower middle) and high-level analyses and visualizations like IBM ManyEyes.</span></p> </div> </div> <div class="section" id="us-03-system-architecture-proposed"> <h2>US 03. System Architecture (proposed)<a class="headerlink" href="#us-03-system-architecture-proposed" title="Permalink to this headline">¶</a></h2> <p>The DataONE architecture must embrace the highly dispersed and independent nature of data collection activities relevant to the environmental and earth sciences. Data are collected by tens of thousands of scientists around the world who have the expertise to describe and archive these data, as well as curate them. Attempting to centralize this curation function is inherently untenable and will not scale. Thus, DataONE will achieve both scalability and sustainability through a highly distributed system architecture (Figures from “Core Architecture” and below) that utilizes the <strong>DataONE Service Interface</strong> to access uniform services provided and used by three types of cyber-infrastructure: (1) <strong>Member Nodes</strong> located at institutions distributed throughout academia, libraries, government agencies, and other organizations that provide local data storage, curation, and metadata for a set of data resources that are collected or affiliated with that institution; (2) <strong>Coordinating Nodes</strong> that are geographically-distributed to provide a high-availability, fault-tolerant, and scalable set of coordinating services to the Member Nodes, including a complete metadata index and data replication services for all data in all Member Nodes; and (3) an <strong>Investigator Toolkit</strong> that provides a complete and evolving set of tools for data and metadata management by scientists and curators throughout the entire data life cycle (Figure 3). Initially, there will be three Coordinating Nodes geographically dispersed at ORC, UNM, and UCSB. A small number of additional Coordinating Nodes may be implemented as DataNetONE expands in scope, sustainable funding, and international presence.</p> <div class="figure" id="id3" style="width: 100%"> <img alt="../_images/proposal_figure_4.png" src="../_images/proposal_figure_4.png" /> <p class="caption"><span class="caption-text">Main features of the DataNetONE architecture, emphasizing distributed data storage at Member Nodes and metadata indexing and services provided by Coordinating Nodes.
