>> I also think that we need a language agnostic markup language to represent the BREP.

I agree with that, but some serious decisions have to be made or it will end up a mess like STEP.

Yeah, agreed. Would be cool to have multiple CAD kernels using the same markup language, then you can easily version control and use it for interchange.

[rjsw]

In what way do you consider STEP to be a mess?

[engr]

ISO 10303-21 is annoying to read and write, with an awful lot of stuff not used by CAD tools

[rjsw]

Don't read or write it then, use software that will do it for you.

I don't know of anything that isn't useful in ISO 10303-21.
