The demes
specification defines a data model for describing one or
more demes (or populations), how they change over time, and their
relationships to one another. A human-readable demes
model is written
as a YAML file, which facilitates model sharing, reuse, and interoperability.
A reference implementation for loading demes
models into python is
available from https://github.com/popsim-consortium/demes-python
