## What is an Address?

**	*****The means of  referencing an object for the purposes of  unique location and identification [BS 7666: Part 3]***

## What is the Address Standard?

- A  Federal Geographic Data Committee (FGDC)  data usability standard that applies to all addresses that have a spatial component.
- This standard does not apply to addresses with out a spatial component. Ex: e-mail addresses

**Notes:**
Purpose of the Address Standard: To facilitate the sharing of address information.It does this by providing a method for documenting the content of address information.This standard is applicable to shared addresses. 

## What is a Data Usability Standard? 

-  *A FGDC standard that describes how to express the applicability of a data set and includes data quality, assessment and reporting standards.*

**Notes:**
There are four types of FGDC standards: data, process, technology and organization. With in the data type, there are five subtypes: data classification, data content, data symbology or presentation, data transfer and data usability.

## What is the Purpose and Objective of the Address Standard?

**Purpose**: *To facilitate the sharing of address information*
**Objective**: *To provide a method for documenting the content of address information*

**Notes:**
This standard is applicable to all shared addresses. Data users will comply with the standard when they share information with other data users. This standard places no requirement on an organization’s internal use of address data.

## Definition: Location

- An identifiable place in the real world.
- Examples
- Eiffel Tower
- Fenway Park
- Washington, DC
- California

**Notes:**
The term location was used in the definition of address.

## Definition: Addressee

**Addressee**: *The final recipient to which a piece of mail is addressed*
- An addressee’s association with an address is “limited” to receiving mail at the address
- Examples:
- Occupant
- Mr. John Smith
- ABC Company

**Notes:**
This is the second of three terms necessary to understand the address standard. 

## Definition: Contact

*The person, firm or establishment associated with an address*
- This may or may not be the addressee.
- A contact’s  association with an address may be much broader
- Examples:
- 1. An owner responsible for paying the property tax for a rented dwelling
- 2. A federal agency maintaining a national monument
- 3. A mining company leasing the mineral rights on a government land parcel

**Notes:**
The term contact can be easily confused with the term addressee. 

## Address Specification

*Documents the data content of an address group*
- It includes
- Address purpose
- The address type
- Descriptive elements
- And if address type = mailing, an address crosswalk

**Notes:**
The address specification has four parts. The next ten slides describe the various parts of the address specification.

## Address Structure Decision Tree

**Address Structure Decision Tree**

**Notes:**
This decision tree helps to determine which of the four mailing structures you should use. This diagram is taken from appendix D (page 24) of the standard.

## The Current Status of the Address Standard

- In the review stage
- Completed public review
- Reviewer’s Comments were incorporated into the standard.
- Examples of changes
- Glossary was added
- A paragraph explaining  the term **mail structure** was added to eliminate confusion between this term and the term  mail or address type

**Notes:**
There are four stages to a FGDC proposal: Final, review, draft and proposal. These stages are further broken into 12 sub-stages. The address standard has completed sub-stage 11: Review: Acting on recommendations.  

## What is next for the Address Standard?

- A Unified Modeling Language (UML) diagram needs to be added
- The UML  diagram will be distributed to SCDD for review
- The comments of  the SCDD will be incorporated into the UML
- The standard will be submitted to the FGDC for public review

**Notes:**
UML is an object oriented modeling language, similar to OMT, Shlaer, and Wirs-Brock. An object is an atomic entity, formed from the union of state and behavior.
