Federal Geographic Data Committee FGDC Document Number FGDC-STD-016-2011 United States Thoroughfare, Landmark, and Postal Address Data Standard 2. Part 2: Address Data Content 2.1 Introduction 2.1.1 Purpose The content part defines address elements, their attributes, and address reference system elements. 2.1.2 Organization The address elements are presented first, grouped according to the major components of an address, followed by the attributes, which are grouped by subject, and lastly the address reference system elements. The Table Of Elements And Attributes immediately following this introduction lists elements and attributes in the order they are presented. 2.1.3 Simple Elements, Complex Elements, and Attributes The content part defines simple elements, complex elements, and attributes. 1. Simple elements are address components or address reference system components that are defined independently of all other elements 2. Complex elements are formed from two or more simple or other complex elements 3. Attributes provide descriptive information, including geospatial information, about an address, an address reference system, or a specific element thereof. Appendix C: Table of Element Relationships lists the relations between simple and complex elements. 2.1.4 Element and Attribute Definitions and Descriptions Each data element is defined and described by giving its: 1. Element name: The name of the element. 2. Other common names for this element: Common words or phrases having the same or similar meaning as the element name. Note: * "(USPS)" indicates terms used in USPS Publication 28. * "(Census TIGER)" indicates terms found in U.S. Census Bureau TIGER\Line Shapefile documentation. * Part 6 gives complete citations for both documents. 3. Definition: The meaning of the element. 16 Federal Geographic Data Committee FGDC Document Number FGDC-STD-016-2011 United States Thoroughfare, Landmark, and Postal Address Data Standard 4. Syntax: (For complex elements only) What component elements are required or permitted to construct the element, and the order in which they must appear. (For syntax notation, see below, "Notation for Constructing Complex Elements.") 5. Definition Source: The source of the definition ("New" indicates that the definition is original.) 6. Data Type: Whether the element is a characterString, date, dateTime, integer, real, or geometric (point, MultiCurve, or MultiSurface) (see "Element and Attribute Data Types" below for definitions) 7. Existing Standards for this Element: Other standards that govern this element (if any). 8. Domain of Values for this Element: The range or set of values (if any) to which the element is restricted. 9. Source of Values: The source (if any) for the domain of values. 10. How Defined: How the domain of values is defined. 11. Example: Illustrative examples of the element. 12. Notes/Comments: Notes and comments giving further explanation about the element. 13. XML Tag: The XML tag for the element. 14. XML Model: XML model of the element. 15. XML Example: The XML model applied to a specific example of the element. 16. XML Notes: Explanatory notes about the XML model. 17. Quality Measures: Quality tests applied to the class. 18. Quality Notes: Explanatory notes about the quality measures applied to this element. 2.1.5 Element and Attribute Data Types Elements and attributes are either non--geometric, geometric, or abstract. Non-geometric data types include characterString, date, dateTime, integer, and real. Geometric data types include point, MultiCurve, and MultiSurface. The abstract data type, as used in this standard, aggregates multiple elements of different data types, geometric and non-geometric. The non-geometric data types are defined in the FGDC's "Framework Data Content Standard Part 0: Base Document" (section 7.8.2.2 (Table 4 - CodeList for DataType)) as follows: 1. characterString: "A CharacterString is an arbitrary-length sequence of characters including accents and special characters from repertoire of one of the adopted character sets" 17 Federal Geographic Data Committee FGDC Document Number FGDC-STD-016-2011 United States Thoroughfare, Landmark, and Postal Address Data Standard 2. date: "Values for year, month, and day" 3. dateTime: "A combination of year, month, and day and hour, minute, and second" 4. integer: "Any member of the set of positive whole numbers, negative whole numbers and zero" 5. real: "Real numbers are all numbers that can be written as a possibly never repeating decimal fraction" The geometric data types are defined in the Open Geospatial Consortium's "OpenGIS(R) Geography Markup Language (GML) Encoding Standard" Version: 3.2.1. (see Part 6 for a complete citation): 1. Point: "...a single coordinate tuple." (Sec. 10.3.1) 2. MultiCurve: "...a list of curves. The order of the elements is significant and shall be preserved..." (Sec. 11.3.3.1). (The MultiCurve replaced the MultiLinestring datatype defined in GML version 3.0) 3. MultiSurface: "...a list of surfaces. The order of the elements is significant and shall be preserved..." (Sec 11.3.4.1). (The MultiSurface replaced the MultiPolygon datatype defined in GML version 3.0) The abstract data type is defined in the FGDC's "Framework Data Content Standard Part 0: Base Document" (Annex B.2.2) as a "class, or other classifier, that cannot be directly instantiated." The abstract data type (used in this standard for the complex element Address Reference System) may aggregate multiple elements of different data types, geometric and non-geometric. 2.1.6 Notation for Constructing Complex Elements The following notation is used to show how complex elements are constructed from simple or other complex elements: {} enclose the name of an element. * indicates that the element is required to create the complex element. Otherwise the element may be omitted when desired. + indicates "and" (concatenation), with a space implied between each component unless stated otherwise. 2.1.7 XML and GML Standard XML models and examples conform to the W3C XML Core Working Group's "Extensible Markup Language (XML) 1.0" (see Appendix A for a complete citation). Geometry elements are defined and implemented following OGC's "OpenGIS(R) Geography Markup Language (GML) Encoding Standard" Version: 3.2.1. 18 Federal Geographic Data Committee FGDC Document Number FGDC-STD-016-2011 United States Thoroughfare, Landmark, and Postal Address Data Standard Table of Elements and Attributes Category Group Element Name Simple/Complex Definition Address Elements Address Number Elements Address Number S The portion of the Complete Prefix Address Number which precedes the Address Number itself. Address Number S The numeric identifier for a land parcel, house, building, or other location along a thoroughfare or within a community. Address Number S The portion of the Complete Suffix Address Number which follows the Address Number itself. Complete C An Address Number, alone or Address Number with an Address Number Prefix and/or Address Number Suffix, which identifies a location along a thoroughfare or within a community. Street Name Elements Street Name Pre S A word or phrase in a Modifier Complete Street Name that 1. Precedes and modifies the Street Name, but is separated from it by a Street Name Pre Type or a Street Name Pre Directional or both, or 2.

Street Name S A word preceding the street Predirectional name that indicates the directional taken by the thoroughfare from an arbitrary starting point or line, 19 Federal Geographic Data Committee FGDC Document Number FGDC-STD-016-2011 United States Thoroughfare, Landmark, and Postal Address Data Standard Category Group Element Name Simple/Complex Definition or the sector where it is located.
