With a postal address, a postal service can deliver items to a premise, P.O. box, or similar. A postal address is not intended to model geographical locations like roads, towns, or mountains. In typical usage, an address would be created by user input or from importing existing data, depending on the type of process. Advice on address input or editing: - Use an internationalization-ready address widget such as https://github.com/google/libaddressinput. - Users should not be presented with UI elements for input or editing of fields outside countries where that field is used. For more guidance on how to use this schema, see: https://support.google.com/business/answer/6397478. # Postal address. See also: https://github.com/googleapis/googleapis/blob/master/google/type/postal_address.proto

Because values in `address_lines` do not have type information and may sometimes contain multiple values in a single field (for example, &quot;Austin, TX&quot;), it is important that the line order is clear. The order of address lines should be &quot;envelope order&quot; for the country or region of the address. In places where this can vary (for example, Japan), `address_language` is used to make it explicit (for example, &quot;ja&quot; for large-to-small ordering and &quot;ja-Latn&quot; or &quot;en&quot; for small-to-large). In this way, the most specific line of an address can be selected based on the language. The minimum permitted structural representation of an address consists of a `region_code` with all remaining information placed in the `address_lines`. It would be possible to format such an address very approximately without geocoding, but no semantic reasoning could be made about any of the address components until it was at least partially resolved. Creating an address only containing a `region_code` and `address_lines` and then geocoding is the recommended way to handle completely unstructured addresses (as opposed to guessing which parts of the address should be localities or administrative areas).

For Spain, this is the province and not the autonomous community (for example, &quot;Barcelona&quot; and not &quot;Catalonia&quot;). Many countries don&#x27;t use an administrative area in postal addresses. For example, in Switzerland, this should be left unpopulated.

This is often the UI language of the input form or is expected to match one of the languages used in the address&#x27; country/region, or their transliterated equivalents. This can affect formatting in certain countries, but is not critical to the correctness of the data and will never affect any validation or other non-formatting related operations.

The date is relative to the Proleptic Gregorian Calendar. If year, month, or day are 0, the DateTime is considered not to have a specific year, month, or day respectively. This type may also be used to represent a physical time if all the date and time fields are set and either case of the `time_offset` oneof is set. Consider using `Timestamp` message for physical time instead. If your use case also would like to store the user&#x27;s timezone, that can be done in another field. This type is more flexible than some applications may want. Make sure to document and validate your application&#x27;s limitations. # DateTime value. Includes date, time, and timezone.

          &quot;addressValue&quot;: { # Represents a postal address, such as for postal delivery or payments addresses. With a postal address, a postal service can deliver items to a premise, P.O. box, or similar. A postal address is not intended to model geographical locations like roads, towns, or mountains. In typical usage, an address would be created by user input or from importing existing data, depending on the type of process. Advice on address input or editing: - Use an internationalization-ready address widget such as https://github.com/google/libaddressinput. - Users should not be presented with UI elements for input or editing of fields outside countries where that field is used. For more guidance on how to use this schema, see: https://support.google.com/business/answer/6397478. # Postal address. See also: https://github.com/googleapis/googleapis/blob/master/google/type/postal_address.proto

Because values in `address_lines` do not have type information and may sometimes contain multiple values in a single field (for example, &quot;Austin, TX&quot;), it is important that the line order is clear. The order of address lines should be &quot;envelope order&quot; for the country or region of the address. In places where this can vary (for example, Japan), `address_language` is used to make it explicit (for example, &quot;ja&quot; for large-to-small ordering and &quot;ja-Latn&quot; or &quot;en&quot; for small-to-large). In this way, the most specific line of an address can be selected based on the language. The minimum permitted structural representation of an address consists of a `region_code` with all remaining information placed in the `address_lines`. It would be possible to format such an address very approximately without geocoding, but no semantic reasoning could be made about any of the address components until it was at least partially resolved. Creating an address only containing a `region_code` and `address_lines` and then geocoding is the recommended way to handle completely unstructured addresses (as opposed to guessing which parts of the address should be localities or administrative areas).

For example, this can be a state, a province, an oblast, or a prefecture. For Spain, this is the province and not the autonomous community (for example, &quot;Barcelona&quot; and not &quot;Catalonia&quot;). Many countries don&#x27;t use an administrative area in postal addresses. For example, in Switzerland, this should be left unpopulated.
            &quot;languageCode&quot;: &quot;A String&quot;, # Optional. BCP-47 language code of the contents of this address (if known). This is often the UI language of the input form or is expected to match one of the languages used in the address&#x27; country/region, or their transliterated equivalents. This can affect formatting in certain countries, but is not critical to the correctness of the data and will never affect any validation or other non-formatting related operations. If this value is not known, it should be omitted (rather than specifying a possibly incorrect default). Examples: &quot;zh-Hant&quot;, &quot;ja&quot;, &quot;ja-Latn&quot;, &quot;en&quot;.
            &quot;locality&quot;: &quot;A String&quot;, # Optional. Generally refers to the city or town portion of the address. Examples: US city, IT comune, UK post town. In regions of the world where localities are not well defined or do not fit into this structure well, leave `locality` empty and use `address_lines`.

This is never inferred and it is up to the user to ensure the value is correct. See https://cldr.unicode.org/ and https://www.unicode.org/cldr/charts/30/supplemental/territory_information.html for details. Example: &quot;CH&quot; for Switzerland.

          &quot;datetimeValue&quot;: { # Represents civil time (or occasionally physical time). This type can represent a civil time in one of a few possible ways: * When utc_offset is set and time_zone is unset: a civil time on a calendar day with a particular offset from UTC. * When time_zone is set and utc_offset is unset: a civil time on a calendar day in a particular time zone. * When neither time_zone nor utc_offset is set: a civil time on a calendar day in local time. The date is relative to the Proleptic Gregorian Calendar. If year, month, or day are 0, the DateTime is considered not to have a specific year, month, or day respectively. This type may also be used to represent a physical time if all the date and time fields are set and either case of the `time_offset` oneof is set. Consider using `Timestamp` message for physical time instead. If your use case also would like to store the user&#x27;s timezone, that can be done in another field. This type is more flexible than some applications may want. Make sure to document and validate your application&#x27;s limitations. # DateTime value. Includes date, time, and timezone.

    <code class="details" id="setDefaultProcessorVersion">setDefaultProcessorVersion(processor, body=None, x__xgafv=None)</code>
  <pre>Set the default (active) version of a Processor that will be used in ProcessDocument and BatchProcessDocuments.

Args:
  processor: string, Required. The resource name of the Processor to change default version. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for the SetDefaultProcessorVersion method.
  &quot;defaultProcessorVersion&quot;: &quot;A String&quot;, # Required. The resource name of child ProcessorVersion to use as default. Format: `projects/{project}/locations/{location}/processors/{processor}/processorVersions/{version}`
}

  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # This resource represents a long-running operation that is the result of a network API call.
