Schemas

CrossContract currently deals only with tabular data but is designed to allow to extend to other data types.

Table schemas

A table schema is a description of each field/column in the data specifying the data type, the semantic meaning of the column, as well as additional constraints on the data (e.g., minimum, maximum, ...). The currently available fields are (check the API references for the most updated versions).

NumberField	Restricts type to be float number	minimum, maximum, enum
StringField	Restricts type to a string	minLength, maxLength, pattern, enum
