DataTank

The DataTank is an open source tool that publishes data, stored in text-based files (e.g., CSV, XML, JSON) or in binary structures (e.g., SHP files, relational databases). The DataTank reads data from these structures and publishes them to the web using a URI as an identifier, providing these data in any format a user wants regardless of the original data structure. The DataTank requires a server with Apache2 or Nginx, mod rewrite enabled, PHP 5.4 or higher, Git, any database supported by Laravel 4.
