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. Many highly relevant data sets have not yet been indexed.
