Google is developing a system that will enable web publishers of any size to automatically submit new content to Google for indexing within seconds of that content being published. Search industry analyst Danny Sullivan told us today that this could be "the next chapter" for Google.
This document describes the protocol used by the Google Data APIs, including information about what a query looks like, what results look like, and so on.
The Google Data APIs provide a simple standard protocol for reading and writing data on the web. These REST-style APIs are based on the Atom Publishing Protocol (AtomPub), using the standard Atom syndication format to represent data and HTTP to handle communication. The Google Data API protocol also extends AtomPub for processing queries, authentication, batch requests, and providing alternate output formats (JSON, RSS). Many Google services support the Google Data API protocol
The Google Data APIs provide a simple standard protocol for reading and writing data on the web. The Data APIs use either of two standard XML-based syndication formats: Atom or RSS. They also have a feed-publishing system that consists of the Atom publishing protocol plus some extensions (using Atom's standard extension model) for handling queries.
The Atom Publishing Protocol is an important new standard for content publishing and management. In this article, explore a high-level overview of the protocol and its basic operation and capabilities.
