This International Standard is a reference model for digital rights management (DRM) functionality for geospatial resources (GeoDRM). As such, it is connected to the general DRM market in that geospatial resources must be treated as nearly as possible like other resources, such as music, text, or services.This International Standard defines:— A conceptual model for digital rights management of geospatial resources, providing a framework and reference for more detailed specification in this area.— A metadata model for the expression of rights that associate users to the acts that they can perform against a particular geospatial resource, and associated information used in the enforcement and granting of those rights, such as owner metadata, available rights, and issuer of those rights.— Requirements that are placed on rights management systems for the enforcement of those rights.NOTE A rights management system must be necessary and sufficient: it must implement only those restrictions necessary to enforce the rights defined therein, and it must be sufficient to enforce those rights.— How this is to work conceptually in the larger DRM context to ensure the ubiquity of geospatial resources in the general services market.
