ProjectUsNormalizer 0.1.0

Project US@ Normalizer

C# library to facilitate address normalization in accordance with Project US@, the "Unified Specification for Addresses in Health Care".

NOTE: This package doesn't validate the existence of an address, it only normalizes fields based on the rules of Project US@ specification.

Usage

Normalize All Address Fields

Address address = new (
  StreetAddress1: "123    Church Pky Avenue West \n",
  StreetAddress2: "Suite 101",
  City: "@Spring \t Hill",
  State: "Tennessee",
  PostalCode: "12345-0123"
);
Address normalizedAddress = address.Normalize();

// The output of normalizedAddress:
// new Address("123 CHURCH PARKWAY AVE W", "STE 101", "SPRING HILL", "TN", "12345-0123")

Normalize Individual Address Fields

Normalize Street Line

string streetLine = "1011 South West Main Thing St North East Apartment 280";
string normalizedStreetLine = streetLine.NormalizeStreetLine();

// The output of normalizedStreetLine:
// "1011 SW MAIN THING ST NE APT 280"

See StreetLineNormalizerTests unit tests for more examples.

Normalize State

string state = "  \nTennessee";
string normalizedState = state.NormalizeState();

// The output of normalizedState:
// "TN"

Parse Street Line Into Individual Components

StreetLineParser is able to parse a given street line into normalized individual street components.

string streetLine = "101 South West Main Thing St North East Apartment 12";
IEnumerable<StreetComponent> parsedStreetComponents = StreetLineParser.Parse(streetLine);

// The output of parsedStreetComponents:
// new List<StreetComponent>
// {
//   new("101", StreetComponentType.PrimaryAddressNumber),
//   new("SW", StreetComponentType.Predirectional),
//   new("MAIN THING", StreetComponentType.StreetName),
//   new("ST", StreetComponentType.Suffix),
//   new("NE", StreetComponentType.Postdirectional),
//   new("APT", StreetComponentType.SecondaryAddressIdentifier),
//   new("12", StreetComponentType.SecondaryAddress)
// }
