Data startup Factual has taken the largest step yet toward solving a problem of our modern, mobile, location-enabled lifestyle. With each restaurant-finding or check-in application, developers are building their own databases of places. Each has its own identifier and no connection to any other listing referencing the same place--a restaurant, park, office building or other landmark. Now Factual has added its "crosswalk" feature to the Factual Places API to address the problem and offer a solution that connects over 500 million web pages to specific venues. Included are the place pages from other directories of places, making Factual a Rosetta Stone for translating identifiers.
After much anticipation since its private beta release in March, Yahoo! has made Fire Eagle publicly available. Fire Eagle is an open geo-location platform that allows users to broadcast their geographic location to the Web while at the same time giving the the ability to easily control how and on which sites location data is shared (our Fire Eagle API profile).
