DataMed

DataMed is a prototype biomedical data search engine. Its goal is to discover data sets across data repositories or data aggregators. In the future it will allow searching outside these boundaries. DataMed supports the NIH-endorsed FAIR principles of Findability, Accessibility, Interoperability and Reusability of datasets with current functionality assisting in finding datasets and providing access information about them. The data repositories covered in this initial release have been selected by the bioCADDIE team and represent only a small sample of biomedical data. DataMed indexes the core metadata available for most datasets, but it offers enhanced search functions when repositories provide additional metadata.DataMed是一款原型生物医学数据搜索引擎。其核心目标是在各类数据存储库与数据聚合平台中发现数据集。未来，该工具将支持突破上述边界的跨源检索。DataMed遵循美国国立卫生研究院（National Institutes of Health，NIH）认可的数据集FAIR原则，即可发现性（Findability）、可访问性（Accessibility）、可互操作性（Interoperability）与可重用性（Reusability），当前功能可辅助用户查找数据集并提供相关访问信息。此次初始版本覆盖的数据存储库由bioCADDIE团队遴选，仅为生物医学数据资源的一小部分样本。DataMed可为绝大多数数据集的核心元数据（metadata）建立索引，当数据存储库提供额外元数据时，其可提供增强型搜索功能。
