Issues with CSOM • No Direct Access to

client.svc Web Service

• Must use a Proxy or

Supported End Points

• Supports .NET Silverlight & JavaScript

REST Overview

What’s REST and Why?

Simple and Easier to

Use • Easier than SOAP Based

WS’s

• Higher Productivity using

JavaScript and JQuery

• Results as JSON and

ATOM

• Everything is URL

• Results can be cached on

Proxy Servers.

REST in SharePoint 2013

Replace

• http://intranet/_vti_bin/client.svc/web

with

• http://intranet/_api/web/

• Lot more simple URL

• Helps in 256 Character Limit of URLs

in browser

• ListData.svc is still there for

backword compatiability

• OLD Aps will still work but needs to

be updated

Client OM and OData

What is OData?

More Information @ http://www.odata.org/

OData Terms and Concepts OData Described in Entity Data Model by

Collection Entity Set A Navigation Property on an entity type that identifies a collection of entities

Entry Entry type Note: May be Part of a type Hierarchy

Property of an Entry Primitive or complex Entity type property

Complex Type Complex Type

Link A Navigation Property defined on an entity type

Service Operation Function Import

Methods will be mapped into either OData Maps CRUD Operations to HTTP Verbs

OData Implementation Details

URLs

Resource Path – SQL Table or Web or List

REST – Return ATOM XML vs. JSON

ATOM-PUB XML

• Verbose

• Easier to Read

• ACCEPT = application/atom+xml

• Condensed notation

• Smaller payload

• ACCEPT =

application/json;odata=verbose;

Example REST URLS

http://Intranet.consoto.com/_api/web/

http://Intranet.consoto.com/_api/web/Lists

http://Intranet.consoto.com/_api/web/Lists/getByTitle(‘Customers’)

http://Intranet.consoto.com/_api/web/getAvailableWebTemplates(lcid=1033

http://Intranet.consoto.com/_api/web/

http://intranet.consoto.com/_api/web/Lists/getByTitle(‘Customers’)/Items(0)/?$select CustomerName,CustomerId,Address

Managing Objects to Resources

Demo : REST in Browser

Summary

CSOM Now Covers More

Important for App Development

REST

Improved Syntax

Easy to Use with JavaScript than C#
