Application Definition File Reference
An application definition file (ADF) is used to build notification applications on the Notification Services platform. The ADF contains metadata that defines the application. This includes the structure of the events and subscriptions that the application accepts as input, and the structure of the notifications it produces.
Your ADF must be an XML file that conforms to the schema described in ApplicationDefinitionFileSchema.xsd, which is in the Microsoft SQL Server\90\NotificationServices\9.0.242\XMLSchemas folder. This schema describes all of the elements used when defining an application.
An ADF contains a hierarchy of XML elements, each containing text or other elements that specify the application settings and structure. The ADF must conform to the standards for well-formed XML, so all element names are case sensitive. Elements are specified using Pascal case, which means that the first character is uppercase and the first letter of any subsequent concatenated word is uppercase.
All element values must conform to XML naming conventions. For more information about these conventions, see XML Textual Content in the MSDN Library.
The following sections list the ADF XML element in the order they appear in an ADF. Not all elements can be used in one ADF. For sample ADF files, see Application Definition File Templates.
