Google Data APIs Overview: All your RSS are belong to Google (that joke never gets old…).

GData is a new protocol based on Atom 1.0 and RSS 2.0.

To acquire information from a service that supports GData, you send an HTTP GET request; the service returns results as an Atom or RSS feed. You can update data (where supported by a particular GData service) by sending an HTTP PUT request, an approach based on the Atom Publishing Protocol.

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. The RSS and Atom models are extensible, so each feed provider can define its own extensions and semantics as desired. A feed provider can provide read-only feeds (such as a search-results feed) or read/write feeds (such as a calendar application).

So, RSS is bad now? Is that right? Was there a memo I missed?



  1. This may be off topic but could someone explain to me how the “All your __ are belong to _” came to be? In particular I really don’t understand the “…are belong…” part.


  2. Do they ever learn their lessons in name-finding and branding? GData is the name of a somewhat large software development company in Germany who does antivirus software, and I’m sure they will not be amused if Google steals their name. Same happened with GMail, which was a trademarked – again – in Germany long before Google started to use it. Can’t they afford some specialists forprofuct names to do proper research?

  3. The Google data API (“GData”) isn’t the name of a Google service or product. It is simply (an abbreviation of) the name of a API protocol model using to construct APIs for Google services, like the Google Calendar data API.

    I’m somewhat confused by the “so, RSS is bad now?” comment in the original post. GData feeds use completely valid Atom or RSS 2.0 feeds. So there is no intent to replace or deprecate either, only to leverage them and make them useful in new ways beyond blog syndication (i.e. data publishing / syndication).
