Please visit https://github.com/cogan-shimizu-wsu/OWL2dl-m for an examination of the source code of the tool.
Currently the tool plays both roles.
If the tool is called from the command line with arguments, it will not launch the gui. Usage is: "java GUI_Converter.jar input.owl output
the command line arguments are expected to be a single file "input.owl" and output is expected to be a directory.
The tool when called with no arguments will launch the gui. The gui allows for any number of files from the same directory to be converted simulataneously. Use the browse buttons to find input and output directories.
There is a known bug that some times delays the output of "Job finished." However, if "post-processing" line has been printed, the file is safe to move and open.
