The business networking site LinkedIn has now launched a new application platform they call InApps. It's an OpenSocial-based platform that enables third-party developers to create applications that get embedded into LinkedIn user's profiles. While this follows along the model used of Facebook, MySpace and host of other social platforms, it differs in its emphasis on being business centric in nature and, like the service itself, follows a much more controlled and button-downed approach. And like the LinkedIn API that we reported on last year, access is limited based on an approval process.
Factual Inc, a company founded by ex-Googler Gil Elbaz that is creating a collaborative data platform, announced extensions to its Factual APIs today that are aimed at improving the ability to target advertising and provide other geo-based capabilities in mobile applications. The three new APIs, Geopulse, Reverse Geocoder, and World Geographies, fill gaps and extend the scope of Factual’s API portfolio. But the way that Factual thinks about its APIs also holds lessons for anyone who is mapping out an API strategy of their own.
