Open Digital Rights Language
File type: Various data file
Files with the dr file extension are associated with the Open Digital Rights Language (ODRL), a language for expressing rights over digital content.
An ODRL document contains rights-related data, such as permissions, prohibitions, duties or constraints.
Found 4 different file type records with the same dr filename suffix.

The DR file extension was associated with the Open Digital Rights Language (ODRL) Initiative, an international effort to develop and promote an open standard for rights expressions.
ODRL is intended to provide flexible and interoperable mechanisms for expressing how digital content may be used. Its purpose includes supporting the publishing, distribution and consumption of digital media across different sectors and communities.
The .dr association is obsolete. Modern ODRL implementations use established structured-data serializations, so an ODRL document may instead use a format such as RDF/XML, Turtle or JSON-LD.
A dr file may be opened in a text editor if it contains a text-based ODRL expression. Software that supports ODRL is needed to validate the rights expression and interpret its permissions, duties and constraints.
Do not rename or edit the file as plain text if its contents are not readable structured data.
There is no general-purpose converter for the obsolete .dr file association. If the file contains valid ODRL data, it can be converted with software that supports the relevant ODRL serialization.
Conversion to a current ODRL serialization is usually performed by an ODRL-aware parser or application. Renaming the extension alone does not convert the file.

Open the .dr file with DRwin on Microsoft Windows. Use the application's Open command and select the project data file.
Use DRwin to save or export the project data in any format supported by the application.

The DR file extension identifies a rights object used by the OMA DRM system. The file stores copy-protection information, including permissions and usage constraints for protected content, in WBXML format.
Sony Ericsson DRM Packager creates and manages the rights objects used with packaged DRM content. The DR file is a rights object rather than the protected media itself.
Open a DR file with Sony Ericsson DRM Packager on Microsoft Windows, or with Sony Ericsson DRM Packager for Mac on Apple macOS or Mac OS X.
A DR file is a rights object rather than a document or media file, so it may not display useful content in a text editor or general-purpose file viewer.
DR files are not normally converted to another file format. They contain DRM permissions and constraints, not standalone media content.
Use the compatible Sony Ericsson DRM Packager to manage the rights object or create a new DRM package. Converting the file generally would not preserve its intended DRM function.
