The former usage pricing model of X downloads in Y days is no longer available by
default. That pricing model is now used, optionally, as a grace period. A grace
period, if configured at deployment, can be attributed to the Every Download
pricing model (see
TABLE 2-10
). Upon purchase, a grace period allows additional
numbers of downloads or extends the download period. The system administrator
can set the properties
pricing.model.recurringDownload.numberOfDays
and
pricing.model.recurringDownload.numberOfTimes
to enable a grace period.
See the Sun Java System Content Delivery Server Installation Guide for information on
setting a grace period.
Each DRM supports some set of the pricing models available in the Content Delivery
Server. The pricing models that you can assign to a content type are dependent on
the DRM that is associated with the content type.
