-        encoding_confidence? (float): Confidence value for encoding function.
-
-        field_type? (str): Enforce all the inferred types to be this type.
-            For more information, please check "Describing  Data" guide.
-
-        field_names? (str[]): Enforce all the inferred fields to have provided names.
-            For more information, please check "Describing  Data" guide.
-
-        field_confidence? (float): A number from 0 to 1 setting the infer confidence.
-            If  1 the data is guaranteed to be valid against the inferred schema.
-            For more information, please check "Describing  Data" guide.
-            It defaults to 0.9
-
-        field_float_numbers? (bool): Flag to indicate desired number type.
-            By default numbers will be `Decimal`; if `True` - `float`.
-            For more information, please check "Describing  Data" guide.
-            It defaults to `False`
-

-            It defaults to `["false", "False", "FALSE", "0"]`
-
-        schema_sync? (bool): Whether to sync the schema.
-            If it sets to `True` the provided schema will be mapped to
-            the inferred schema. It means that, for example, you can
-            provide a subset of fileds to be applied on top of the inferred
-            fields or the provided schema can have different order of fields.
-
-        schema_patch? (dict): A dictionary to be used as an inferred schema patch.
-            The form of this dictionary should follow the Schema descriptor form
-            except for the `fields` property which should be a mapping with the
-            key named after a field name and the values being a field patch.

-
-        licenses? (dict[]): The license(s) under which the resource is provided.
-            If omitted it's considered the same as the package's licenses.
-
-        sources? (dict[]): The raw sources for this data resource.
-            It MUST be an array of Source objects.
-            Each Source object MUST have a title and

-
-        detector? (Detector): File/table detector.
-            For more information, please check the Detector documentation.
-
-        onerror? (ignore|warn|raise): Behaviour if there is an error.
-            It defaults to 'ignore'. The default mode will ignore all errors
-            on resource level and they should be handled by the user
-            being available in Header and Row objects.
-
-        trusted? (bool): Don't raise an exception on unsafe paths.
-            A path provided as a part of the descriptor considered unsafe
-            if there are path traversing or the path is absolute.
-            A path provided as `source` or `path` is alway trusted.
-
-        package? (Package): A owning this resource package.
-            It's actual if the resource is part of some data package.

-    Parameters:
-
-        source (any): Source of the package; can be in various forms.
-            Usually, it's a package descriptor in a form of dict or path
-            Also, it can be a glob pattern or a resource path
-
-        descriptor (dict|str): A resource descriptor provided explicitly.
-            Keyword arguments will patch this descriptor if provided.
-
-        resources? (dict|Resource[]): A list of resource descriptors.
-            It can be dicts or Resource instances.
-
-        id? (str): A property reserved for globally unique identifiers.
-            Examples of identifiers that are unique include UUIDs and DOIs.
-
-        name? (str): A short url-usable (and preferably human-readable) name.
-            This MUST be lower-case and contain only alphanumeric characters
-            along with “.”, “_” or “-” characters.
-
-        title? (str): A Package title according to the specs
-           It should a human-oriented title of the resource.
-
-        description? (str): A Package description according to the specs
-           It should a human-oriented description of the resource.
-
-        licenses? (dict[]): The license(s) under which the package is provided.
-            If omitted it's considered the same as the package's licenses.
-
-        sources? (dict[]): The raw sources for this data package.
-            It MUST be an array of Source objects.
-            Each Source object MUST have a title and
-            MAY have path and/or email properties.
-
-        profile? (str): A string identifying the profile of this descriptor.
-            For example, `fiscal-data-package`.
-
-        homepage? (str): A URL for the home on the web that is related to this package.
-            For example, github repository or ckan dataset address.
-
-        version? (str): A version string identifying the version of the package.
-            It should conform to the Semantic Versioning requirements and
-            should follow the Data Package Version pattern.
-
-        contributors? (dict[]): The people or organizations who contributed to this package.
-            It MUST be an array. Each entry is a Contributor and MUST be an object.
-            A Contributor MUST have a title property and MAY contain
-            path, email, role and organization properties.
-
-        keywords? (str[]): An Array of string keywords to assist users searching.
-            For example, ['data', 'fiscal']
-
-        image? (str): An image to use for this data package.
-            For example, when showing the package in a listing.
-
-        created? (str): The datetime on which this was created.
-            The datetime must conform to the string formats for RFC3339 datetime,
-
-        innerpath? (str): A ZIP datapackage descriptor inner path.
-            Path to the package descriptor inside the ZIP datapackage.
-            Example: some/folder/datapackage.yaml
-            Default: datapackage.json
-
-        basepath? (str): A basepath of the resource
-            The fullpath of the resource is joined `basepath` and /path`
-
-        detector? (Detector): File/table detector.
-            For more information, please check the Detector documentation.
-
-        onerror? (ignore|warn|raise): Behaviour if there is an error.
-            It defaults to 'ignore'. The default mode will ignore all errors
-            on resource level and they should be handled by the user
-            being available in Header and Row objects.
-
-        trusted? (bool): Don't raise an exception on unsafe paths.
-            A path provided as a part of the descriptor considered unsafe
-            if there are path traversing or the path is absolute.
-            A path provided as `source` or `path` is alway trusted.
-
-        hashing? (str): a hashing algorithm for resources
-            It defaults to 'md5'.
-
-        dialect? (dict|Dialect): Table dialect.

This allows for comparison prior to casting and for fields to have missing value which are not of their type, for example a `number` field to have missing values indicated by `-`.\n\nThe default value of `missingValue` for a non-string type field is the empty string `''`.
