Dear devs,
I don't know if this has been discussed before. Lyx uses it's own
format .layout (or .module), with it's own parser. However, the same
information can be easily saved stored in another format. I asked a
chatbot to convert "amsbook.layout" to an hypothetical "amsbook.yaml"
file:
format: 104
columns: 1
sides: 2
page_style: Headers
docbook_root: book

I think it looks pretty good. The advantages of using an industry standard are:
1. People already know the format. This could encourage publishers to
provide layouts.
2. Existing and solid tools for parsing can be used. Even if not
directly by LyX, someone manipulating layouts externally doesn't need
to reinvent the wheel.
Let me know what you think.
