Gdata, short for Google Data APIs, promises to be Google’s new standard protocol for transmitting all sorts of data back and forth to Google and its various services. As Google states on Google Code: “All sorts of services can provide GData feeds, from public services like blog feeds or news syndication feeds to personalized data like email or calendar events or task-list items.” Imagine for instance, starting with a base feed, then adding query parameters like restricting to a particular category and date range and ending up with a customized feed that specifically fits your criteria. Gdata builds on the RSS 2.0 and ATOM 1.0 protocols.
Imagine your desktop machine — armed with your personal profile — communicating with Google (and even with the Web in general) about your email, search history, RSS subscriptions, calendar, bookmarks, blog posts, and the news… and all through the GData protocol. As Reto Meier states, “Google already has a ridiculous amount of my information. Now with an API that promises access to this information to use the way I want to, there’s one less reason to think about storing it anywhere else.” Kinda scary but also exciting at the same time. Google Operating System here we come!
Will we all be speaking GData in years to come? Will the GData protocol become as ubiqitous as the HTTP protocol? Only time will tell, but I certainly think GData is one to watch!
