Introduction to Collaborative Application Markup Language (CAML)
Collaborative Application Markup Language (CAML) is an XML-based language that is used in Microsoft SharePoint Foundation to define the fields and views that are used in sites and lists.
CAML is case-sensitive.
CAML can be used in various ways to customize a SharePoint site, including the following:
In script or code that implements members of the SharePoint Foundation object model, where CAML strings are passed through method parameters, assigned to properties, or returned by methods and properties
In SOAP messaging that passes CAML strings to a SharePoint Foundation Web service to interact remotely with a deployment
In front-end site definitions used to instantiate SharePoint sites
In SharePoint Foundation Features to add specific functionality within a particular scope
