SchemaDefinition¶

class tracdap.metadata.SchemaDefinition¶

A schema definition describes the schema of a dataset

Schema definitions can be top level objects (a type of object definition), in which case they can be referred to by multiple data definitions. Alternatively they can be embedded in a data definition to create datasets with one-off schemas.

A table schema describes the schema of a tabular data set. Other schema types may be added later, e.g. for matrices, tensors, curves, surfaces and structured datasets.
