The Basic Model Interface (BMI)
summary
A minimal, language-agnostic set of about ~30 functions exposes initialize run step get/set and finalize so models remain runnable without BMI yet become pluggable; mappings exist for Python Fortran C Julia JavaScript and Rust and examples use a 2D heat equation; adoption includes NOAA Next Gen Modeling Framework and is community governed by a council; current work adds extension hooks for parallelism and geospatial features with a version 3 target Sep 2027.
