The rdfs:Range
construct allows you to define list of literals, which can be
viewed as help-values (suggestions) when the property is displayed in the Advanced Search
criteria, or selected to create explicit tags. For explicit tags, you can define a range
with help values to extend the definition of 6W root properties.
The following example shows how you can define help-values for the
ds6w:how
property using the owl:oneOf
construct.
