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.
Turn any dataset into a RESTful HTTP API


Mapstraction is a Javascript library. It provides developers with a single interface for a wide variety of Javascript map APIs including Leaflet, Google, Bing, OpenLayers and ESRI's ArcGIS.
A key benefit is that once a developer has loaded Mapstraction, s/he can to switch from one map API to another quickly and easily - often only needing to change a few lines of code.
Mapstraction displays points, lines, polygons and markers on the maps, and also allows developers to add base maps and overlays.
