We’ve had OpenId to make the transport of your ID easier between Web sites. We’ve had initiatives on Data Portability to make it easier for you to move your data around between social networks and other apps. But what we haven’t had yet is a way to allow you to share your location between different mobile social platforms. That’s something that a new, largely European-inspired, initiative hopes to address. The alliance, called OSLO (Open Sharing of Location-based Objects) includes many of the players in mobile social networking and location-based social software. Twelve startups, all of whom serve their users with location-based services, have signed an agreement to enable their combined 30 million users to share location information and interact between networks. Currently most location-based systems operate in a similar fashion to instant messaging systems, and don’t interoperate. The question is, will Google’s Latitude and Yahoo!’s FireEagle come on board?
