The Temboo Android builds Android applications that connect to over 100 web-based resources and services (e.g. Facebook, Dropbox, US Census data) by standardizing how it interacts with APIs. The Android SDK allows developers to create applications that use Google's Geocoding API to retrieve the Latitude and Longitude for a specific address.
Structured data has an open platform, thanks to a new startup aptly named Factual. At first glance, it seems like Excel on the web. However, Factual is more database-oriented, with joining and filtering built-in. Plus, sharing and discussing the data is an integral part of the experience. Most functions on the site, including both reading and writing data, can also happen via the Factual API.
