Exversion is hoping the need to access wide-ranging open datasets has matured enough to create a viable business as an open data marketplace. Their new Exversion API provides developers with a RESTful interface to search and access the open datasets stored on the Exversion data platform. At present, the API returns queries in JSON or XML format, with full XML support to be provided in the near future.
Building APIs not only requires discipline; ideally, the process also should be incorporated within the actual development process of the application. With that goal in mind, Zend, a provider of application development tools for building PHP applications, is promoting the adoption of a new open-source Apigility project that provides a standardized way to build and maintain multiple versions of an API.
