Abstract

This document describes a simple RDF vocabulary for describing the relationship between things and maps of those things. It is designed to integrate smoothly with the GeoRSS vocabulary and the forthcoming W3C Geospatial Vocabulary.

Following is a brief example, showing a map describing the Leytonstone area of London. (Leytonstone itself is identified using a Geonames URI.)

<rdf:RDF
  xmlns:geonames = "http://www.geonames.org/ontology#"
  xmlns:georss   = "http://www.georss.org/georss/"
  xmlns:map      = "http://downlode.org/Code/RDF/Map/"
  xmlns:rdf      = "http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:rdfs     = "http://www.w3.org/2000/01/rdf-schema#"
>

<map:Map rdf:about="http://mt2.google.com/mt?x=16384&amp;y=10887&amp;zoom=2">
  <map:shows>
    <geonames:Feature rdf:about="http://sws.geonames.org/6692921/">
      <rdfs:label>Leytonstone, London, UK</rdfs:label>
    </geonames:Feature>
  </map:shows>
  
  <map:covers rdf:parseType="Resource">
    <georss:box>51.5630 0.0000 51.5702 0.0115</georss:box>
  </map:covers>
</map:Map>

</rdf:RDF>

Here is a differently-oriented example, relating an RDF resource to a map.

<rdf:RDF
  xmlns:geonames = "http://www.geonames.org/ontology#"
  xmlns:map      = "http://downlode.org/Code/RDF/Map/"
  xmlns:rdf      = "http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:rdfs     = "http://www.w3.org/2000/01/rdf-schema#"
>

<geonames:Feature rdf:about="http://sws.geonames.org/6692921/">
  <rdfs:label>Leytonstone, London, UK</rdfs:label>

  <map:shownBy>
    <map:Map rdf:about="http://mt2.google.com/mt?x=16384&amp;y=10887&amp;zoom=2" />
  </map:shownBy>
</geonames:Feature>

</rdf:RDF>
