ISO 15836:2003 is applicable to the Dublin Core metadata element set which deals with cross-domain information resource description. For Dublin Core applications, a resource will typically be an electronic document.
ISO 15836:2003 is for the element set only, which is generally used in the context of a specific project or application. Local or community based requirements and policies may impose additional restrictions, rules, and interpretations. It is not the purpose of ISO 15836:2003 to define the detailed criteria by which the element set will be used with specific projects and applications.
