ADL Gazetteer Content Standard
(version of 4/21/99)

In the following content standard description, an asterisk (*) indicates a required (mandatory) data element and the element name is in bold; otherwise, the data element is optional. When a required element is a part of a non-required compound element, the requirement applies only when that compound element is applicable. (R) indicates a repeatable data element; otherwise, the data element is not repeatable.

Labels for the data elements are enclosed in angle brackets < ....... >
Explanations of application are enclosed in square brackets [......... ]
Default values are enclosed in parentheses ( ....... )
Permitted values are enclosed in squiggly brackets { ........}

This standard permits contributions to one geographic feature description from multiple contributors. A particular gazetteer entry (i.e., one feature id and associated description) can be initially entered by one contributor and additional information can be added by others. All mandatory elements must be entered by the original contributor. For simplicity, all major sections of the Standard are structured with attribution elements for contributor and source, with the following exceptions. The Geographic Feature ID will be assigned to the entry by the system; Type of Geographic Feature and Other Classification Terms each have an identification of the schemes from which the terms are selected. A general Entry Note field is provided as a place to explain unusual circumstance.

 Major sections of the Standard:
