Document(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Document represents the canonical document resource in Document Understanding AI. It is an interchange format that provides insights into documents and allows for collaboration between users and Document Understanding AI to iterate and optimize for quality.

This message has oneof_ fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.

Name	Description
uri	str Optional. Currently supports Google Cloud Storage URI of the form gs://bucket_name/object_name. Object versioning is not supported. See `Google Cloud Storage Request URIs
content	bytes Optional. Inline document content, represented as a stream of bytes. Note: As with all bytes fields, protobuffers use a pure binary representation, whereas JSON representations use base64. This field is a member of oneof_ source.
mime_type	str An IANA published MIME type (also referred to as media type). For more information, see https://www.iana.org/assignments/media-types/media-types.xhtml.
text	str Optional. UTF-8 encoded text in reading order from the document.
