Having blogged about my website as it developed I forgot to blog about the semantic app concept I came up with!
Here is a mockup of the app:
The idea uses multiple social networks and social media platforms to aggregate the locations of your friends using a mixture of geolocation and other location technologies.
The application would use platforms such as Facebook, twitter and Instagram to gain the locations of your friends!
The reason this is not possible now is that it is currently not possible to aggregate the data needed using semantic coding, this is due to the individual platforms not being coded in a way that conforms to the new semantic web coding conventions.
