To follow up on a thought I Twittered t’other day, picking up on a comment of Dennis Crowley‘s: most public objects – and certainly all municipal objects – should offer APIs. (A concrete example: BART‘s provisions.)
Furthermore, specifically with regard to public infrastructures like transit systems, I believe that this should be a matter of explicit government policy.
What’s a public object? A sidewalk. A building facade. A parking meter. Any discrete object in the common spatial domain, intended for the use and enjoyment of the general public. Any artifact located in or bounding upon public rights-of-way. Any discrete object which is de facto shared by and accessible to the public, regardless of its ownership or original intention. How’s that for starters?
