Field Definitions
Applies to: SharePoint Foundation 2010
Each element manifest file that defines site columns must adhere to the Field Definition Schema.
A site column is a reusable column definition, or template, that you can assign to multiple lists across multiple SharePoint sites. Site columns decrease rework and help you ensure consistency of metadata across sites and lists. For example, suppose you define a site column named Customer. Users can add that column to their lists, and reference it in their content types. This ensures that the column has the same attributes—at least to start with—wherever it appears. Much like site content types, you define a site column at the site level, independent of any actual list or content type.
For more information about site and list columns, see Introduction to Columns.
XML Schema Definition
An element manifest that defines site columns must validate with the schema in the file wss.xsd. This file is located on the following path: %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\TEMPLATE\XML.
Example
The following example shows an element manifest for a Feature that creates four site columns.
