OMA Digital Rights Management V2.1.2
OMA DRM v2.1 has been developed as a result of market feedback. The main differences between OMA DRM v2.0 and OMA DRM v2.1 are the addition of several features on top of OMA DRM v2.0, including:
- Metering, primarily intended for information gathering. By means of metering, actual content usage information can be provided to Rights Issuers, thereby enabling royalty collection based on actual usage of content.
- Content differentiation, defining a mechanism to control how content can be consumed. For example, this mechanism can prevent that a music track is used as ringtone.
- RO installation confirmation.
- Additional metadata, such as artist, title and genre
- Support for user editable metadata, in addition to content issuer defined metadata.
- A binary format for ROAP triggers to improve communication efficiency.
- New domain property (noConsumeAfter) to simplify 'temporary sharing' business models
- RO upload functionality to enable users to upload Rights from their old device to a Rights Issuer so that these Rights can be downloaded to their new device.
- Improved extensibility for future versions.
The DRM 2.1 features have minimum impact on the DRM 2.0 architecture and are defined in a DRM 2.0 backward compatible manner.
