Mixi [JP] (TSE:2121) held a conference to introduce their new service “Mixi Appli”. Mixi Appli provides an OpenSocial-based application platform for developers.

Mixi Appli is one of the three services provided on “Mixi Platform”. Mixi Platform provides Mixi Appli, Mixi Connect (OAuth) and Mixi OpenID.

Mixi Appli provides 5 APIs such as Person & Friends API, Community API, Activities API, Persistence API, and API.

He predicted that the next generation of Web sites are going to be based on social graph. Social graph based sites are not “globally social” like Digg, Flickr or Youtube. Social graph based services have values such as “sharing”, “contextual” and “empathy”.

Mixi Appli provides two methods of monetization for developers. One is a Mixi official ad program which pays per pageview. Ad revenue starts from 0.01yen ($0.0001) per pageview, and the revenue increases proportionally with pageviews and uniqueusers. Another is a Mixi payment API. Mixi payment API supports micro-payment.

Harada announced Social Application Award, the award which is given to the best Mixi Appli. The winner receives a million yen ($10,000).

Mixi Appli will be officially launched on August 2009. Subsequently, Mixi ad program and Mixi Appli for mobile launches on September.
