@ronaldtse From what I understand we need to support something like what xpath does i.e lutaml_model_instance.model_path(<expression>).

Is this correct?

[ronaldtse]

Yes, that's correct. What we are doing in root_mappings / child_mappings is like that:

    map_root to: :units, root_mappings: { id: :key, name: %w[root_units enumerated_root_units] }

i.e. root_units enumerated_root_units => in YAML input.root_units.enumerated_root_units.

We need to think about it.

[ronaldtse]

We have a gem for lutaml-path.

We need a specification for lutaml-path and to extend it.
