SharePoint 2013 Content

The following are the new Content (Enterprise Content Management) features in SharePoint 2013.

Feature	Description
Standard and Simplified Web Development	SharePoint 2013 enables developing solutions using Web Standard technologies like HTML, JavaScript , CSS, etc and supports Open protocols like OAuth and OData. This helps standardizing the development process and enables easy sharing of information with other platforms.
BCS – OData Support	Business Connectivity Services now allows connections to applications/services which use the OData Protocol. SharePoint can now expose data in a format which supports OData and also access external data which are modeled based on OData Protocol. Visual Studio 2010 can automatically generate the BDC model for external OData sources, to help accessing data easily.
BCS – REST Support	REST endpoint are defined for almost all the API in the Client Object Model, hence SharePoint 2013 can share information requested using REST format URIs
BCS - External Content Types Support	External content types can now be accessed from SharePoint 2013 using WCF Services
BCS - External Event Receivers Support	Now event receivers can be defined to trigger when a change happens outside the SharePoint 2013 system, Ex: We can define an event receiver to trigger when data changes in an external database.
Apps	Apps are complete modules on their own, they contain all the resources required for them to function, Apps can be plugged in into SharePoint sites to provide additional functionality, without any change to the underlying SharePoint system, they are light weight and easily portable, hence can be installed and un-installed easily.
BCS – App Support	BCS connections can be defined with App scope, and can be stored separately. These BCS models are stored in the App itself, hence reducing dependency on the Server.
External lists	Lists based on external data now allow paging and sorting before rendering the list to improve performance.
Site-based retention	SharePoint 2013 allows retention policies to be applied at a site level, so that the policy is applied uniformly to all the contents in the site. When the site policy expires the policy of all sub items get expired automatically, and finally get deleted along with the site policy. The site retention policy also applies to the Exchange server mailboxes associated with the site, so when the site policy expires and get deleted, the associated emails also get deleted automatically.
