URD files are associated with the Universal Network Objects (UNO) component model used by OpenOffice.org. The UNO IDL compiler creates these files from interface definition language (IDL) source files.
A URD file contains compiled UNO type and reflection information. Development tools use this information when building UNO components and language bindings. URD files can also be combined into a UNO type registry database for use by the OpenOffice.org runtime and SDK tools.
The format is a developer-oriented intermediate format, not an OpenOffice.org document format. It is mainly encountered in projects that build or extend UNO components.
A URD file is not normally opened for reading in a desktop application. Use the OpenOffice.org UNO Software Development Kit and its command-line development tools to process the file.
If the file was supplied with a software project, keep it with the related UNO IDL sources and build files. A text editor cannot display its compiled contents meaningfully.
There is no general-purpose converter for URD files. To obtain a new URD file, compile the original UNO IDL source again with the UNO IDL compiler.
For use in a UNO type registry, the OpenOffice.org SDK tools can merge URD files into a registry database. This is a build-time operation rather than a normal document conversion.
