The extractor_mime_type_binding core model stores the explicit MIME-to-extractor routing table used by the knowledge extractor runtime.

This model is the persistence layer behind:

• module_sdk.extractors.list_configurable_mime_bindings()
• module_sdk.extractors.list_ingestible_mime_types()
• module_sdk.extractors.set_mime_type_binding(...)
• module_sdk.extractors.resolve(...)

What This Model Represents¶

Rows include:

• id
• mime_type
• extractor_id

mime_type is normalized to lowercase. extractor_id is normalized to lowercase.

Only one binding can exist for a given MIME type.

Boundary¶

Most module code should use module_sdk.extractors instead of manipulating this model directly.

Use the extractor SDK methods when you want validation that:

• the extractor exists
• the extractor is installed or active
• the extractor supports the selected MIME type

Direct model CRUD is useful for generic admin tables and diagnostics, but it does not replace the domain-level validation in sdk.extractors.

Listing Bindings¶

Example:

listing = module_sdk.models.extractor_mime_type_binding.list(
    page=0,
    page_size=100,
    filters={"mime_type": "application/pdf"},
)

Supported filters include:

• id
• mime_type
• extractor_id

Creating A Binding¶

Example:

created = module_sdk.models.extractor_mime_type_binding.create(
    {
        "mime_type": "application/pdf",
        "extractor_id": "docling",
    }
)

The model requires both fields and rejects duplicate MIME bindings.

For user-facing configuration actions, prefer:

module_sdk.extractors.set_mime_type_binding(
    mime_type="application/pdf",
    extractor_id="docling",
)

That method validates extractor compatibility before writing the row.

Updating And Deleting¶

Update and delete behave like ordinary core-model registry operations:

updated = module_sdk.models.extractor_mime_type_binding.update(
    row_id,
    {"extractor_id": "docling"},
)
deleted = module_sdk.models.extractor_mime_type_binding.delete(row_id)

Deleting a row makes the MIME type non-ingestible until another extractor is configured for it.
