CLDXF provides a standard XML schema for the exchange of civic address data along with guidance on how to populate the address elements. It implements the IETF standard Presence Information Data Format Location Object (PIDF-LO) and is largely derived from and consistent with the United States Thoroughfare, Landmark, and Postal Address Data Standard from the Federal Geographic Data Committee (FGDC).
CLDXF is a key standard, a critical component of any NextGeneration 9-1-1 project and one which impacts numerous other NENA documents, so it’s important to get it right. This workgroup will deal with a few issues that have been identified by other workgroups and by users of the standard. The intent is to complete our work in an expedited fashion. One set of issues relates to the management of sub-address data, especially in locations like campuses, residential complexes, malls or trailer parks where ordinary civic addresses may not provide sufficient precision.
The group will revisit the building and landmark/landmark part elements and will develop additional guidance and possibly new structure.The group will also consider additional guidance for the formatting of other sub-address elements, and revisit the definitions of place name elements which are confusing and may not accommodate local conditions and determine if a more flexible approach is needed.
