Query regarding core:view and mvc:view in XML view

Hello Experts,

Can someone explain in brief or re-direct me to appropriate link to understand the difference between core:view and mvc:view in XML view of SAPUI5/Fiori application?

When we start an application in Eclipse and create XML view using sap.m library we see core:view, but in sample applications in SAPUI5 SDK - Demo Kit, we are seeing mvc:view. Please help us understanding when to use what.

<core:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m"

  controllerName="splitapptest.Master" xmlns:html="http://www.w3.org/1999/xhtml">

  <Page title="Title">

</core:View>
