The Google Base API makes it possible to get items in and out of Google Base; a free service for submiting various content for Google to host and to make searchable online. The service allows content providers to upload structured data (including jobs, vehicles, recipes, events, products, reviews, and others) to Google, surface it across Google search properties, and syndicate it via apis, gadgets and gadget ads.
The Google Base data API is designed to enable developers to do two things: (1) Query Google Base data to create applications and mashups. (2) Input and manage Google Base items programmatically. The query API makes it possible to search all of Google Base using attribute-based search refinements. For example, Google Base enables you to query for [used white toyota prius near mountain view, ca] by specifying condition, color, make, and other attributes. Using the Google Base Data API, developers can programmatically access Google Base. This allows for management of structured data, searching for data and syndicating content.
Items inserted to Google Base may surface on Google.com. For example, see the query [used toyota] and the vehicles refinement option.
The database that tried to be everything to everyone is being replaced by more specific tools. The Google Base API, launched in 2005, has been deprecated. In its place, Google suggests using its new Google Shopping Search API for finding products and Shopping Content API for merchants to add products. The new APIs will help Google focus on the most common uses of Google Base. However, the change means that developers will have to update code and that some non-shopping applications will be left without a replacement.
Yahoo has announced some new updates to SearchMonkey its relatively new platform that allows web sites and web content publishers to format and custom search results on Yahoo search pages. The new updates include additional content types that can be included in search results and support for Google Base formatting for structured data feeds (our Google Base API Profile).
