The Internet spawned hopes for a golden age of government transparency, but while many government agencies have adopted digital technology, functional transparency remains elusive. Achieving transparency means becoming aware of how data can, through deliberate manipulation or technical ignorance, be locked away in formats that make it difficult to access or analyze.
