DataMed is a search and discovery service focused on biomedical datasets. Its stated purpose is to help users find biomedical data, track its reuse, and measure its impact, bringing information about datasets and repositories together in one place. The service presents itself as a one-stop shop for searching across millions of biomedical datasets and offers a Search API for accessing its search functionality.

DataMed also provides views that organize information by repository, dataset, author, usage, publication mentions, year, and s-index. These tools are intended to help users explore repository activity, see which datasets are used or mentioned, and identify authors associated with the data. The site includes summaries of repository activity and dataset mentions and usage, supporting assessment of how biomedical data is being referenced and reused. The supplied page shows these sections, although its displayed totals are zero, so it does not establish current repository, dataset, author, or impact counts. Overall, DataMed is presented as a resource for locating biomedical datasets and examining their visibility and reuse.
