Hyper media Software Network Architecture.

Protocol is: Client-server, Stateless, Cacheable, Layered

REST presents numerous benefits other WEB SERVICES:

Does not require a separate discovery mechanism.

Not as dependant on Vendor Software.

Simplified Client Side interface.

Improve scalability and lighter weight.

Statelessness Client - isolate client / server

Application that exposes a Web UI and links things together.

REST Representational State Transfer Not a Standard but an Architectural Style that use standards protocols: HTTP URL Resource Representations: XML/HTML/GIF/JPEG/… Mime Types: text/xml, text/html, image/gif, image/jpeg, application/json

Not a Standard but an Architectural Style that use standards protocols:

HTTP

URL

Resource Representations: XML/HTML/GIF/JPEG/…

Mime Types: text/xml, text/html, image/gif, image/jpeg, application/json

Principles REST Service Design URL to each resource using nouns, not verbs (http://rest.parts.com/parts/90fh3 accessible via HTTP GET, POST, PUT and/or DELETE) Enable GET clients to drill down to get more information by revealing data gradually. Specify format response using DTS, W3C, RelaxNG or Schematron and provide specific schema for POST and PUT. Document service invocation into HTML or WSDL document.

REST in WCF? Resource-oriented services that implement uniform interfaces using standard HTTP (GET, POST, PUT, and DELETE), and that can be query by a URI. Microsoft improved “REST support within WCF was enhanced with the release of .NET Framework 3.5 SP1 to add make REST development easier and to support the ADO.NET Entity Framework entities in WCF contracts.” New HTTP NET CLIENT Class. Server Side Features. HTTP Request Header "text/xml“ for XML “ and application/json“ for JSON XHttpMethodOverride to post DELETE and PUT Http request REST Service Cache Duration settings Security enable with RequestInterceptor WebException serialized as JSON or XML HTTP Asynchronous Client programming model XML/XSD Type

XML/XSD Type

Exposing XSD with REST? XSD describes the structure of a XML document. VS Command prompt XSD.exe generates code from a XML schema Definition. c:dev
est xsd parts.xsd Create a WCF Service interface in Visual Studio [serviceContract] using [XMLSerializerFormat] Create the class that implement the interface methods. Web.config settings to support RESTfull representation webHttpBinding
