The .kmt file extension is associated with Kermeta, a language and development environment for creating metamodels. A Kermeta file stores metamodel data and Kermeta source code used by the environment.
Kermeta files are used as part of Kermeta projects and are processed by Kermeta or the Kermeta integration for Eclipse. Kermeta and Eclipse tools are available for Microsoft Windows, while Eclipse with Kermeta support is also available on macOS and Linux/Unix systems.
The MIME type commonly associated with this format is application/octet-stream.
On Microsoft Windows, open the .kmt file with Kermeta. On Windows, macOS, or Linux/Unix, use Eclipse with the Kermeta support installed.
Opening the file in a plain-text editor may show its source code, but Kermeta or Eclipse is needed to interpret it as part of a Kermeta project.
There is no general-purpose conversion utility for the .kmt file format. It is a source file rather than a document intended for conversion.
Open the file in Kermeta or Eclipse to edit and process it. The environment may generate other project artifacts from the source, but those outputs are not a direct conversion of the original file.
