rpm files are packages (rpm = Redhat Package Manager) which are also usable in Fedora.
You'll need to install them.
However, the file you mentioned is a source rpm (*.src.rpm), which means that the package doesn't contain the
program (binary), just the source code.
You can install this source rpm and then compile the source code to get the program.
Or you can see if you can find the *.rpm file instead (for your platform), download it, and then install it via
rpm -i your_rpm_file
If you already have a package installed with the same name (check that with "rpm -q package_name"), then you may go for the "rpm -u your_rpm_file" (update) rather than the -i (install).
