We build OpenSocial applications using a common API. This API is used to access data and the core functions. We provide the following OpenSocial application development services:Social Mashup: It is a small application that runs within an application. It is developed using HTML, JavaScript, CSS, Social Application: This app too runs inside of a social network but it relies on an external server for processing and rendering data. Social Website or Social Mobile Application: Social websites and social mobile applications run outside social networks but consume social data through REST or RPC APIs. The web is better when it's social.The web is more interesting when you can build apps that easily interact with your friends and colleagues.
