ISO On-Line Resources

How ISO Does It

As the World Wide Web has developed into a ubiquitous information source, links to on-line information and services have become a critical element in all metadata records. These links are treated very differently in the FGDC and ISO standards. In the FGDC, URLs are free text. In the ISO, they are CI_OnlineResource objects that include a rich set of fields for describing the on-line resource.

CI_OnlineResource + linkage : URL
+ protocol [0..1] : CharacterString
+ applicationProfile [0..1] : CharacterString
+ name [0..1] : CharacterString
+ description [0..1] : CharacterString
+ function [0..1] : CI_OnLineFunctionCode
