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.
