# OpenAPI v3.0 schema classes
## Alias
Due to the reserved words in python and pydantic,
the following fields are used with [alias](https://pydantic-docs.helpmanual.io/usage/schema/#field-customisation) feature provided by pydantic:
| Class | Field name in the class | Alias (as in OpenAPI spec) |
| ----- | ----------------------- | -------------------------- |
| Header[*](#header_param_in) | param_in | in |
| MediaType | media_type_schema | schema |
| Parameter | param_in | in |
| Parameter | param_schema | schema |
| PathItem | ref | $ref |
| Reference | ref | $ref |
| SecurityScheme | security_scheme_in | in |
| Schema | schema_format | format |
| Schema | schema_not | not |
> <a name="header_param_in"></a>The "in" field in Header object is actually a constant (`{"in": "header"}`).
> For convenience of object creation, the classes mentioned in above
> have configured `allow_population_by_field_name=True` (Pydantic V1) or `populate_by_name=True` (Pydantic V2).
>
> Reference: [Pydantic's Model Config](https://pydantic-docs.helpmanual.io/usage/model_config/)
## Non-pydantic schema types
Due to the constriants of python typing structure (not able to handle dynamic field names),
the following schema classes are actually just a typing of `Dict`:
| Schema Type | Implementation |
| ----------- | -------------- |
| Callback | `Callback = Dict[str, PathItem]` |
| Paths | `Paths = Dict[str, PathItem]` |
| Responses | `Responses = Dict[str, Union[Response, Reference]]` |
| SecurityRequirement | `SecurityRequirement = Dict[str, List[str]]` |
On creating such schema instances, please use python's `dict` type instead to instantiate.

Structural validation alone may be insufficient to validate that an
instance meets all the requirements of an application. The "format"
keyword is defined to allow interoperable semantic validation for a
fixed subset of values which are accurately described by
authoritative resources, be they RFCs or other external
specifications.
The value of this keyword is called a format attribute. It MUST be a

this set, validation for this format attribute and instance SHOULD
succeed.

Unlike JSON Schema, the value MUST conform to the defined type for the Schema
Object defined at the same level. For example, if `type` is `string`, then
`default` can be `"foo"` but cannot be `1`.**
From JSON Schema:
There are no restrictions placed on the value of this keyword.
This keyword can be used to supply a default JSON value associated
with a particular schema. It is RECOMMENDED that a default value be
valid against the associated schema.
This keyword MAY be used in root schemas, and in any subschemas.
"""
"""
Other than the JSON Schema subset fields, the following fields MAY be used for
further schema documentation:
"""
nullable: Optional[bool] = None
"""
A `true` value adds `"null"` to the allowed type specified by the `type` keyword,
only if `type` is explicitly defined within the same Schema Object.
Other Schema Object constraints retain their defined behavior,

A `false` value leaves the specified or default `type` unmodified.
The default value is `false`.

A property MUST NOT be marked as both `readOnly` and `writeOnly` being `true`.
Default value is `false`.
