It's funny that when I talk to people in the travel industry about mashups and APIs, most of them get glazed looks in their eyes. Throw in terms like location based services or geospatial awareness and I've lost them. What most of them don't realize is that the majority of the travel apps that are starting to come out, both online and for mobile are mashups that are relying on location awareness and geospatial data. Many of them, like Pocketvillage are a consumer interface on top of a variety of APIs all normalized for a single homogenous user experience. That's right, it's essentially a metasearch tool that pulls in content from a variety of sources including Viator, GetYourGuide, TourCMS, Rezgo, AirBnB, and many others. What differentiates a metasearch like Pocketvillage from other metasearch applications however, is the fact that with location based services enabled, Pocketvillage can return content based on your current location. The issue right now however is that not all geo data is equal. Not all APIs provide geolocation information and some return it based on different criteria.
Back in February 2010 we asked Why can't you share photos on Foursquare? We discussed that this could be seen as an oversight or an opportunity for others. However, this question has now been deprecated by Foursquare with the introduction of its add photo API method, which suggests that the previous absence of a method was simply because it wasn't a priority, it was an oversight or the opportunity hasn't been taken up by developers as Foursquare had hoped. In addition to the new add photo method, Foursquare have also introduced API methods which allow comments to be added and deleted from checkins. These methods have already been rolled into the official iPhone and Android apps along with a few 3rd party apps that use the Foursquare API.
For months, the Bing Maps site has been showing off what are essentially embedded mashups. You can search nearby tweets, FourSquare check-ins and other content from partners. Until now, it was merely a showcase of apps either written internally or by a company that Microsoft had blessed. Now, you have the opportunity to get your mashup included on Bing's map.
