# SchemaInputAttribute
<a name="API_SchemaInputAttribute"></a>

A configuration object for defining input data fields in AWS Entity Resolution. The `SchemaInputAttribute` specifies how individual fields in your input data should be processed and matched.

 ** fieldName **   <a name="API-Type-SchemaInputAttribute-fieldName"></a>
A string containing the field name.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 255.  
Pattern: `[a-zA-Z_0-9- ]*`   
Required: Yes

 ** type **   <a name="API-Type-SchemaInputAttribute-type"></a>
The type of the attribute, selected from a list of values.  
LiveRamp supports: `NAME` \| `NAME_FIRST` \| `NAME_MIDDLE` \| `NAME_LAST` \| `ADDRESS` \| `ADDRESS_STREET1` \| `ADDRESS_STREET2` \| `ADDRESS_STREET3` \| `ADDRESS_CITY` \| `ADDRESS_STATE` \| `ADDRESS_COUNTRY` \| `ADDRESS_POSTALCODE` \| `PHONE` \| `PHONE_NUMBER` \| `EMAIL_ADDRESS` \| `UNIQUE_ID` \| `PROVIDER_ID`   
TransUnion supports: `NAME` \| `NAME_FIRST` \| `NAME_LAST` \| `ADDRESS` \| `ADDRESS_CITY` \| `ADDRESS_STATE` \| `ADDRESS_COUNTRY` \| `ADDRESS_POSTALCODE` \| `PHONE_NUMBER` \| `EMAIL_ADDRESS` \| `UNIQUE_ID` \| `IPV4` \| `IPV6` \| `MAID`   
Unified ID 2.0 supports: `PHONE_NUMBER` \| `EMAIL_ADDRESS` \| `UNIQUE_ID`   
Normalization is only supported for `NAME`, `ADDRESS`, `PHONE`, and `EMAIL_ADDRESS`.   
If you want to normalize `NAME_FIRST`, `NAME_MIDDLE`, and `NAME_LAST`, you must group them by assigning them to the `NAME` `groupName`.   
If you want to normalize `ADDRESS_STREET1`, `ADDRESS_STREET2`, `ADDRESS_STREET3`, `ADDRESS_CITY`, `ADDRESS_STATE`, `ADDRESS_COUNTRY`, and `ADDRESS_POSTALCODE`, you must group them by assigning them to the `ADDRESS` `groupName`.   
If you want to normalize `PHONE_NUMBER` and `PHONE_COUNTRYCODE`, you must group them by assigning them to the `PHONE` `groupName`. 
Type: String  
Valid Values: `NAME | NAME_FIRST | NAME_MIDDLE | NAME_LAST | ADDRESS | ADDRESS_STREET1 | ADDRESS_STREET2 | ADDRESS_STREET3 | ADDRESS_CITY | ADDRESS_STATE | ADDRESS_COUNTRY | ADDRESS_POSTALCODE | PHONE | PHONE_NUMBER | PHONE_COUNTRYCODE | EMAIL_ADDRESS | UNIQUE_ID | DATE | STRING | PROVIDER_ID | IPV4 | IPV6 | MAID`   
Required: Yes

 ** groupName **   <a name="API-Type-SchemaInputAttribute-groupName"></a>
A string that instructs AWS Entity Resolution to combine several columns into a unified column with the identical attribute type.   
For example, when working with columns such as `NAME_FIRST`, `NAME_MIDDLE`, and `NAME_LAST`, assigning them a common `groupName` will prompt AWS Entity Resolution to concatenate them into a single value.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 255.  
Pattern: `[a-zA-Z_0-9- ]*`   
Required: No

 ** hashed **   <a name="API-Type-SchemaInputAttribute-hashed"></a>
 Indicates if the column values are hashed in the schema input.   
If the value is set to `TRUE`, the column values are hashed.   
If the value is set to `FALSE`, the column values are cleartext.  
Type: Boolean  
Required: No

 ** matchKey **   <a name="API-Type-SchemaInputAttribute-matchKey"></a>
A key that allows grouping of multiple input attributes into a unified matching group.   
For example, consider a scenario where the source table contains various addresses, such as `business_address` and `shipping_address`. By assigning a `matchKey` called `address` to both attributes, AWS Entity Resolution will match records across these fields to create a consolidated matching group.  
If no `matchKey` is specified for a column, it won't be utilized for matching purposes but will still be included in the output table.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 255.  
Pattern: `[a-zA-Z_0-9- ]*`   
Required: No

 ** subType **   <a name="API-Type-SchemaInputAttribute-subType"></a>
The subtype of the attribute, selected from a list of values.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 255.  
Pattern: `[a-zA-Z_0-9- ]*`   
Required: No
