The latest release of our Open Platform Content API exposes for the first time the concept of 'references' on our tags and articles. Within our domain model, a 'reference' makes a link to either something in the 'real world', or to a specific piece of data in another system.
The Google Data APIs (Google Data) provide a simple protocol for reading and writing data on the web. Though it is possible to use these services with a simple HTTP client, this library provides helpful tools to streamline your code and keep up with server-side changes.
GPS Visualizer is a free, easy-to-use online utility that creates maps and profiles from GPS data (tracks and waypoints, including GPX files), driving routes, street addresses, or simple coordinates. Use it to see where you've been, plan where you're going, or visualize geographic data (business locations, scientific observations, events, customers, real estate, geotagged photos, "GPS drawing," etc.).
A heat map is a graphical representation of two dimensional data (X, Y and Value) on a two dimensional surface by using colors. On a map a heat map is a representation of density of latitude and longitude points on a map. HeatmapAPI lets you creates heat map images you can overlay on your maps in your software.
"Take any kind of street address list copied from Excel and geocode the addresses to get latitude and longitude coordinates using the tool below. The data can then be mapped in your browser, printed, downloaded into Google Earth, saved to a web page, or transferred back into your spreadsheet. It's fast, easy, and - free to use!"
At the CETIS conference this month I facilitated a session on the "University API", which was an opportunity to discuss what kinds of services institutions could offer for public access to developers, rather like BBC Backstage.
"Add the Conversation element so visitors can post comments and links on your site or participate in global Google Friend Connect conversations. Posted comments can be automatically translated into a visitor's preferred language--instantly." Wonder if there's an easy generic way of doing this in jQuery or some such, without requiring a Google account.
"Welcome to the AMEE Developer site. AMEE is a neutral, open platform for measuring energy consumption. This platform is exposed as a RESTful HTTP-based web service with XML, JSON and Atom interfaces. "
"At Paul Smith’s College, I recently implemented a “New Books” display using open APIs and an image scroller. In this article I’ll give a brief overview of Google Book Search, OpenLibrary and Worldcat, explain how I created this New Books Widget using book cover data, and provide readers with some practical and simple code to show how to collect this data. This article will be of interest to anyone who wants to read about a brief overview of current state of free book data service providers. Additionally, beginner programmers will likely find the examples at the end of the article helpful when getting started with projects of their own."
