Select from the Length or Inherit column whether this Vocabulary inherits its properties, at least in part, from another Vocabulary. If no other Vocabularies exist, only the No inheritance option is available. Note that unless a JSON schema was uploaded when this Vocabulary was created, its root name is mainSchema. The JSON schema root contains the JSON schema properties as noted in the Property column. The default setting for the Length or Inherit column is No inheritance, meaning this Vocabulary does not reference properties from another Vocabulary.
