The Open Data Protocol
This posts presents another initiative to open-up data sources by mean of standard Web technologies such as HTTP, Atom Publishing Protocol (AtomPub) and JSON: the Open Data Protocol (OData).
OData (which seems to be mainly supported by Microsoft) is a Web protocol for querying and updating data. OData can be used to give access to a variety of sources, such as relational databases, file systems, content management systems and traditional Web sites.
The New York City Metropolitan Transportation Authority recently decided to release their transit data to the public. Examples of release data are about the subway, buses, railroads, etc.
The goal of MTA is to enable the creation of new mash-up services, such as the WayFinder Mobile Application for iPhone, an augmented reality application that has been designed to designed to help locating the nearest subway, bus or train stations.
The main goal of Fusion Tables is to make it easier for people to create, manage and share on structured data on the Web. Fusion Tables is a new kind of data management system that focuses on features that enable collaboration. [] In a nutshell, Fusion Tables enables you to upload tabular data (up to 100MB per table) from spreadsheets and CSV files. You can filter and aggregate the data and visualize it in several ways, such as maps and time lines. The system will try to recognize columns that represent geographical locations and suggest appropriate visualizations. To collaborate, you can share a table with a select set of collaborators or make it public. One of the reasons to collaborate is to enable fusing data from multiple tables, which is a simple yet powerful form of data integration. If you have a table about water resources in the countries of the world, and I have data about the incidence of malaria in various countries, we can fuse our data on the country column, and see our data side by side.
