This document summarizes efforts to publish clinical quality data from health.data.gov as linked open data. It describes releasing metadata and data from the Hospital Compare project as RDF using vocabularies like VoID, FOAF and DC. Tools like Google Refine, Top Braid Composer and Virtuoso were used to transform, model and serve the data. A community of practice seeks to evolve standards and share best practices for publishing government linked data.
