Schema object classes and field types that define the structure and validation of data in Superlinked.

​
SchemaObject

SchemaObject(base_cls: type)
@schema decorated class that has multiple SchemaFields. Use it to represent your structured data to reference during the vector embedding process.

​
Descendants

​
Properties

​
schema_fields
Sequence[SchemaField]
Collection of schema fields that define the structure of this schema object.

​
SchemaField

SchemaField(name: str, schema_obj: SchemaObjectT, type_: type[SFT], nullable: bool)
A SchemaField is a generic field of your @schema decorated class. SchemaFields are the basic building block for inputs that will be referenced in an embedding space. Sub-types of a SchemaField are typed data representations that you can use to transform and load data to feed the vector embedding process.

​
Parameters

​
name
str
required
Name of the schema field.
​
schema_obj
SchemaObjectT
required
The schema object this field belongs to.
​
type_
type[SFT]
required
The type of the field.
​
nullable
bool
required
Whether the field can have null values.
