Read and Write on Restful Services using Atompub

The Atom Publishing Protocol is the most popular model for read/write RESTful services. If you have developed WCF Data Services then, it supports oData which is nothing but Atompub support. It is used for Publishing and editing web resources using HTTP and XML 1.0. The protocol supports the creation of Web Resources and provides facilities for:

• Collections: Sets of Resources, which can be retrieved in whole or in part.
• Services: Discovery and description of Collections.
• Editing: Creating, editing, and deleting Resources.

Protocol Model

The Atom Protocol specifies operations for publishing and editing Resources using HTTP. It uses Atom-formatted representations to describe the state and metadata of those Resources. It defines how Collections of Resources can be organized, and it specifies formats to support their discovery, grouping and categorization.
