Agenda

What’s CSOM?
REST, OData, OAuth

What’s CSOM?
SharePoint has two frameworks for development:
Server-side object model
Used to run code on the server.
Eg: WebParts, workflows, taxonomies and so on.

Client-side object model (CSOM)
Used to develop code that runs outside of
the SharePoint server.
Eg: Applications you have on your desktop, mobile etc.

What’s CSOM?
Introduced in SharePoint 2010
Multiple implementations
Managed:
.NET Framework
& Silverlight
JavaScript

CSOM - SharePoint 2013

Expanded significantly!

Increased coverage from CSOM in SharePoint

Business Data

Critical Part of the App Model.
SharePoint apps cannot run any server-side
code inside the SharePoint host environment.

Four permutations for writing code in
a SharePoint app:
Client-side JavaScript that uses CSOM
Client-side JavaScript that uses the REST API
Server-side C# code that uses CSOM
Server-side C# code that uses the REST API


SharePoint 2010 SharePoint 2013

CSOM – APIs, Tools and Libraries

REST, OData and OAuth

REST (Representational State Transfer) has a lot of
industry momentum.
It is a style of Software Architecture for distributed
systems.

For SharePoint 2013
Nearly every API in the client object model
has a corresponding REST endpoint.

REST, OData and OAuth

http://www.odata.org/

ODATA is the new data access API like ADO.

It standardizes data access APIs
Becoming really popular and used by Netflix, Azure
and other industry leaders
Supports formats like:
Atom, JSON or plain XML

REST, Odata, OAuth

The OAuth is an open authorization framework.

It enables a application to obtain access to an
HTTP service.

It is meant to keep the authentication conflicts
to a minimum.
