-Obo format translation of the FMA, omitting all relationships other than is_a, part_of and has_part. Future versions of fma_obo will include more relationships
+After many years of maintaining a bespoke OBO-format translation of the FMA — restricted to the is_a, part_of, and has_part relationships — we have now deprecated this project.
+Users are encouraged to use the official FMA release instead: `http://purl.org/sig/ont/fma.owl`.
+Note that the current official FMA release has unsatisfiable classes. Please follow [this issue](https://github.com/OBOFoundry/OBOFoundry.github.io/issues/21) to keep yourself up to date.
