Trait

A trait helps express the semantic meaning and structural guidance. Traits are essentially a metadata's metadata. Traits can extend other traits and have a format that's easy to understand and follow. For example, the trait is.partition.format.CSV describes a data partition in CSV format and has parameters that can provide additional information, such as which character to use as a delimiter.
