This document outlines the roadmap for Healthdata.gov. It describes how Healthdata.gov started as a rushed initial phase 1 project to launch a new portal by June 2013 for an event. It discusses how Healthdata.gov serves 3 audiences (internal publishers, academics/researchers, and developers/entrepreneurs) and aims to achieve 3 speeds (Web 1.0, 2.0 and 3.0) and 3 goals (discovery, programmatic access, and creating "linkages"). The roadmap outlines future phases to simplify publishing, improve search capabilities, focus on APIs, and build a health data marketplace and knowledge graph.
