Online scripture languages to gospel library catalog process

Hello, I've been searching for a bit and can't seem to find the process by which online xml/html versions of the scriptures as offered on scriptures.lds.org are converted to content that can be fetched by Gospel Library via the Gospel Library Catalog web api. Is there such a process? or are both services creating content from some main place and Gospel Library Catalog just hasn't caught up yet (it currently only has English, Spanish and German available).

I would like to get other languages of the scriptures from Gospel Library, but haven't seen them yet.

thanks,
Jeremy
