This document summarizes the work of developing a Data Discovery Index prototype that helps users find and access shared biomedical data from various repositories. It ingests metadata from different standards and sources using ElasticSearch. It was presented at the Alan Turing Institute Symposium in April 2016. The project aims to organize data through an aggregator framework and portal. It involves mapping various metadata standards to have maximum coverage of use cases with minimal data elements.
