[semantics-public] Semantic map between X3D and Blender Python

[John Carlson]

Moved to semantics-public.

It appears like the best way to read in X3D and produce Blender python, or
writing an X3D library to produce Blender python is creating a semantic
mapping between X3D and Blender.  I believe we have a semantic description
of X3D (somewhere).  I’m wondering if anyone has a semantic description of
the  Blender python API?

I know that semantic mapping was discussed in documentation in this group,
but I just heard about converting X3D to Turtle.  Is there Turtle file for
the X3D schema or X3DUOM?

I will look for those, but I’m primarily interested in Blender.  Can I
point a tool at the Blender API docs or source code and have the tool
produce Turtle or similar? Swagger might be a tool for that?

Is MapForce the only tool out there for mapping between semantic
descriptions?   Does it produce good reports?

I’m guessing compilers are the state of the art?

How can one create a compiler from a mapping between semantic descriptions?

Thanks,

John
