Figure 1: Attributes of the Place class.

The Place class is a subclass of the Concept class used for annotating geographic real-world entities. To annotate Place objects with detailed geographic metadata, implementors should use the The GeoCoordinates class.

The Place class specifies the attribute featureCode. This attribute is used to indicate what kind of geographic entity is indicated by a Place object. The IPTC suggests, but does not require, that implementors of rNews populate this field with values drawn from the controlled vocabulary of feature codes provided by geonames.org.

Place Attribute Summary

The table below presents the properties of the Place class and provides both the expected data type and a definition of each attribute.

Applying the Place Class
Our sample article contains five places:
  • Libya
  • France
  • Great Britain
  • United States
  • Turkey
For illustrative purposes we'll also consider two additional locations mentioned in the article.
  • Tripoli
  • White House
To express these concepts in RDF/Turtle using attributes from the rnews Concept and Place classes, we would write the following: 
      
        @prefix rdf:  <http://www.w3.org/1999/02/22-rdf-syntax-ns#>  .
        @prefix rnews: <http://iptc.org/std/rNews/2011-10-07#> .
