Example

The following snippet shows how a data type, written in native code, is defined within the System.Performance management pack.

<DataType ID="System.Performance.SignatureEntry" Base="System!System.BaseData" Accessibility="Public">
  <Implementation>
    <ClassID>AEB2011B-7AD5-4A03-910F-312228EAE0F7</ClassID>
  </Implementation>
</DataType>

The following is a snippet that shows a data type has been written in managed code. The data type is defined in the Microsoft.SystemCenter.Library management pack.

<DataType ID="Microsoft.SystemCenter.DataItemAlertSubscription" Comment="alert change data item type" Accessibility="Public" Base="System!System.BaseData">
  <Implementation>
    <Assembly>Microsoft.Mom.AlertSubscriptionDataSourceModule, Culture="", PublicKeyToken="31bf3856ad364e35", Version="6.0.4900.0"</Assembly>
    <Type>Microsoft.EnterpriseManagement.Mom.
AlertSubscriptionModule.DataItemAlertSubscription</Type>
  </Implementation>
</DataType>

This final snippet shows a data type has been written in both native and managed code. The data type is defined in the System.Performance management pack.

<DataType ID="System.Performance.SignatureData" Base="System!System.BaseData" Accessibility="Public">
  <Implementation>
    <Assembly>Microsoft.Mom.Modules.DataTypes, Culture="", PublicKeyToken="31bf3856ad364e35", Version="6.0.4900.0"</Assembly>
    <Type>Microsoft.EnterpriseManagement.Mom.
Modules.DataItems.Baselining.MOMSignatureDataItem</Type>
    <ClassID>5B44DF33-D67D-4500-85AE-7AE29CA11985</ClassID>
  </Implementation>
</DataType>
