The recent Executive Order Making Open and Machine Readable the New Default for Government Information and the Office of Management and Budget (OMB) Memorandum Open Data Policy – Managing Data as an Asset have brought much attention to efforts to promote the use of data by the US federal government. In fact, highlights of the US Federal Open Data Project are already impressive. Many agencies already provide their data in machine-readable formats through APIs, or at least downloadable data sets. However, I personally measure “highlights” in terms of the use of the data (not by the number of data sets accessible). And, many organizations already put this data to good uses in health, energy, education, safety, and finance. My recent blog, Open Data Isn’t Just For Governments Anymore, highlighted several examples of companies built on open data. Think Symcat, Healthgrades, oPower, or even Zillow which has been using public data for a while now. How many of you have “zillowed” your house, your neighbor’s house, or even a colleague’s house? Be honest. I have.
