Please expand on taxonomies and if they can use the full depth of the data format specification (YAML, JSON, TOML) or if they're limited to a simple key:value / term: value format. Thinking here of how a taxonomie built using YAML should be abl to contain multi-values like collections.

The example on Actors is also not consistent due to lack of a example data for YAML/TOML/JSON
