Updated 6/20/2011: My Reading Office 365 Beta’s SharePoint Online Lists with the Open Data Protocol (OData) post of 6/20/2011 replaces this article due to an incompatibility problem with Windows Live Writer 2011.
The new post expands on the use of Fabrice Marguerie’s Sesame Data Browser to read and query OData feeds. Sesame won’t open OData content generated by SharePoint Online due to issues with required claims-based federated authentication. The updated post explains these issues.
A later post will provide details about adding, updating, and deleting OData content.
