GData (Google Data Protocol) provides a simple protocol for reading and writing data on the Internet, designed by Google. GData combines common XML-based syndication formats (Atom and RSS) with a feed-publishing system based on the Atom Publishing Protocol, plus some extensions for handling queries. It relies on XML or JSON as a data format.

According to the Google Developers portal, "The Google Data Protocol is a REST-inspired technology for reading, writing, and modifying information on the web. It is used in some older Google APIs."^[3] However, "Most Google APIs are not Google Data APIs."

Google provides GData client libraries for Java, JavaScript, .NET, PHP, Python, and Objective-C.

Implementations
