Thanks for the links. This also seems to use its own data format¹ for
defining the keyboards, but it looks like it is much more
mature/flexible than the other options I have seen so far.

FWIW, I had written a tool² which could parse XKB layout definitions
(symbol files) and produce the corresponding SCIM layouts, and I have
used it to generate OFW keytables as well³. I think that this tool
(with some modifications) will be able to migrate our existing
keyboard layouts to the format required by fvkbd.

Thanks,
Sayamindu
