Yahoo! announced details about BOSS V2. "Early in 2011, BOSS will transition to a paid model and we'll round out new version with monetization options and advanced security access (oAuth). BOSS V2 platform will initially offer a cost-per-query model. Cost will depend on the type of services used -- web, image, news, etc. -- and will likely vary from $0.40 to $0.75 CPM (cost per 1000 BOSS queries). Shortly after BOSS V2 release, developers will also have option to monetize their search experience through the ad marketplace resulting from Yahoo! and Microsoft Search Alliance. In addition, we plan to offer a nominally-priced version of BOSS for academia and non-profit organizations," Yahoo explained.
"We plan to provide BOSS developers with 60 days from the launch of BOSS V2 to move to new service. After that, BOSS V1 willn't be available. Certain features, including structured data, Key Terms, Delicious data, and Site Explorer Service mayn't be available in BOSS V2," added Yahoo!.
