ADL Gazetteer Content Standard (version of 7/21/98)

    Relational Database Model (Qi Zheng)

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 two exceptions. The Geographic Feature ID will be assigned to the entry by the system and the Type of Geographic Feature is assumed to be assigned by the original contributor or by system administrators based on a controlled vocabulary of type terminology. A general Entry Note field is provided as a place to explain unusual circumstance.

 Major sections of the Standard:

    1. Geographic Feature ID
    2. Geographic Name
    3. Variant Geographic Name (R)
    4. Type of Geographic Feature (R)
    5. Geographic Feature Code (R)
    6. Spatial Location (R)
    7. Street Address
    8. Non-Spatial Relationship (R)
    9. Description
    10. Geographic Feature Data (R)
    11. Link to Related Source of Information (R)
    12. Supplemental Note
    13. Metadata Information
