Open technologies involve sharing data over the Internet, and all kinds of governments can use them, for all kinds of reasons. Recent public policies have stretched the label “open government” to reach any public sector use of these technologies. Thus, “open government data” might refer to data that makes the government as a whole more open (that is, more transparent). It might equally well refer to politically neutral public sector disclosures that are easy to reuse, but that may have nothing to do with public accountability. Today a government can call itself “open” if it builds the right kind of website — even if it does not become more transparent or accountable.
