Description
" XrML 2.0, announced on November 26, 2001, can be used in content-centric as well as service based business models. Rights and conditions can be securely assigned at varying levels of granularity to individuals as well as groups of individuals and the parties can be authenticated. In addition, the grants/licenses can be interpreted and enforced by the consumption application. XrML is designed to be used in either single tier or multi-tier channels of distribution with the downstream rights and conditions assigned at any level. In addition, the trust environment can also be specified in the language in order to maintain the integrity of the rights and conditions.
XrML 2.0 is extensible and fully compliant with XML namespaces using XML schema technology. XrML 2.0 extensions can be designed for specific industries or with the inclusion of other elements, such as resource-level metadata standards like ONIX and RDF. In addition, standards such as XSLT and XPath have been employed in XrML, and XML Signature and XML Encryption have been used for authentication and protection of the rights expressions. This extensibility makes the language scale with the complexity of business models captured." (http://www.xrml.org/about.asp)
