Interface DRMPackager

All Known Implementing Classes:

J2MEDRMPackager

public interface DRMPackager

DRMPackager is an object to package DRM policy with the content. The implementation must follow the static factory pattern by providing the following API.

 public static DRMPackager getInstance() {
   //.....
 }

Every request for packaging would call this factroy method to obtained a reference, followed by call to packageDRMContent(). packageDRMContent() method which should package the content based on the Digital Rights Policy, ODRL document, etc. It is anticipated that some implementations may not specify ODRL definition; others may optionally support ODRL. Such implementations of packageDRMContent() must safeguard aginst the null values of ODRL XML Document.
