The Dublin Core metadata element "Coverage" offers a Placename subelement which could encode e.g. "Minnesota", either as free text or using a defined vocabulary from a gazetteer. Other subelements x,y allow a geographic location lat/long or a more precisely defined polygonal area. ISO/DIS 3166-2 (countries and their subdivisions) may be considered for the Placename element. Dublin Core elements may currently be embedded in HTML using the META tag, but elements are unstructured (it is difficult to define inheritance between different elements, for instance). RDF offers a structured metadata syntax using XML, and may perhaps be embeddable within HTML before XML is fully deployed. RDF does not address the metadata content. Syntax of specific Dublin Core elements are available in Draft form - start from http://purl.oclc.org/metadata/dublin_core/ Andrew Daviel TRIUMF & Vancouver-Webpages
