15. REST Overview

16. 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.

17. REST in SharePoint 2010

18. 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

19. Client OM and OData

20. What is OData?
More Information @ http://www.odata.org/

21. 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

22. Methods will be mapped into eitherOData Maps CRUD Operations to HTTP Verbs
OData Implementation Details
More Information @ http://www.odata.org/

23. URLs
Resource Path – SQL Table or Web or List

24. 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;

25.  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’)/Ite
ms(0)/?$select CustomerName,CustomerId,Address
Managing Objects to Resources
