Open Mobile Alliance Digital Rights Management (OMA DRM) is a mechanism used for protecting distributed content. Using DRM, the content can be accessed on authenticated devices depending on the usage rights set by the content owner. OMA DRM addresses the various technical aspects of this system by providing appropriate specifications for content formats, protocols, and a rights expression language.
On Nokia devices, DRM properties can be set with Nokia Mobile Internet Toolkit
For more information about DRM, see documents OMA DRM 1.0 specification and OMA DRM 2.0 specification at Open Mobile Alliance web site, and document DRM Developers Guide for Nokia Devices at Forum Nokia web site.
