Building RESTful Python Web Services

Understanding the tasks performed by each HTTP method

The following table shows the HTTP verbs, the scope, and the semantics for the methods that our new API must support. Each method is composed of an HTTP verb, a scope, and all the methods have well-defined meanings for all the resources and collections:

HTTP verb	Scope	Semantics
GET	Collection of message categories	Retrieve all the stored message categories in the collection and return them sorted by their name in ascending order. Each category must include the full URL for the resource. Each category must include a list with all the details for the messages that belong to the category. The messages don't have to include the category in order to avoid repeating data.
