    r"""Instance of a general MetadataSchema.

    Attributes:
        name (str):
            Output only. The resource name of the
            MetadataSchema.
        schema_version (str):
            The version of the MetadataSchema. The version's format must
            match the following regular expression:
            ``^[0-9]+[.][0-9]+[.][0-9]+$``, which would allow to
            order/compare different versions. Example: 1.0.0, 1.0.1,
            etc.
        schema (str):
            Required. The raw YAML string representation of the
            MetadataSchema. The combination of [MetadataSchema.version]
            and the schema name given by ``title`` in
            [MetadataSchema.schema] must be unique within a
            MetadataStore.

            The schema is defined as an OpenAPI 3.0.2 `MetadataSchema
            Object <https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#schemaObject>`__
        schema_type (google.cloud.aiplatform_v1beta1.types.MetadataSchema.MetadataSchemaType):
            The type of the MetadataSchema. This is a
            property that identifies which metadata types
            will use the MetadataSchema.
        create_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. Timestamp when this
            MetadataSchema was created.
        description (str):
            Description of the Metadata Schema
