Omics Discovery Index

The Omics Discovery Index (OmicsDI) provides dataset discovery across a heterogeneous, distributed group of Transcriptomics, Genomics, Proteomics and Metabolomics data resources, including both open and controlled access data resources. The resource provides a short description of every dataset, including accession, description, sample/data protocols biological evidences, and publication. Based on these metadata, OmicsDI provides extensive search capabilities, as well as identification of related datasets by metadata and data content where possible. In particular, OmicsDI identifies groups of related, multi-omics datasets across repositories by shared identifiers.

组学发现索引（Omics Discovery Index，简称OmicsDI）可实现跨异构分布式转录组学（Transcriptomics）、基因组学（Genomics）、蛋白质组学（Proteomics）及代谢组学（Metabolomics）数据资源的数据集检索服务，涵盖开放访问与受控访问两类数据资源。该资源为每个数据集提供简短描述，内容包含登录号、数据集说明、样本与数据实验方案、生物学证据及相关发表文献。基于上述元数据（metadata），OmicsDI提供全方位检索功能，并可在可行条件下依据元数据与数据内容识别相关数据集。尤为特别的是，OmicsDI可通过共享标识符，识别各数据存储库中具有关联关系的多组学数据集群组。
