Generating a License for Metered Content
After receiving a metering certificate from a metering aggregation service, a license issuer generates a license for metered content as follows:
- When a license request is received for metered content, the license issuer uses the WMRMLicGen.MeteringCertificate property to specify which metering certificate to use.
- The corresponding metering ID and URL are then added to the license, and all actions for the corresponding content will be metered.
Example Code
' Declare variables. Dim LicenseObj ' WMRMLicGen object Dim MeterCert ' Metering certificate Dim LicenseKID ' Key ID Dim LicenseKey ' Key Dim RightsString ' Rights string Dim varClientInfo ' Client information Dim ContentServerPubKey ' Public key of the content server Dim IndiVersion ' Security version of the DRM component Dim varLicense ' License ' Specify your metering certificate (XML string). ' The following is a sample metering certificate. ' VBScript requires you to use double quotes for quotes within the string.
