.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
An object of this class is returned by the RDF::Helper
\&\f(CW\*(C`get_object\*(C'\fR method, which takes a \fBsubject\fR \s-1URI\s0 as the first
argument, and optionally a hash or hashref of options as the second
argument.
.PP
On this object, you may then call methods that correspond to property
names of the properties you want to get or set.
.PP
For properties in the default namespace, you may use them without any
regard to prefixes, whereas with properties in other namespaces, you
need to use the prefix and an underscore before the property name.
.PP
This class does not make any attempt to verify whether the methods are
actually valid properties within the used schema, it just blindly does
what you tell it to. It is suitable for creating relatively simple \s-1RDF\s0.
.PP
To set more than one object, use an arrayref as argument, e.g.
.PP
.Vb 1
\&  $obj\->rdfs_label([\*(AqFoo\*(Aq, \*(AqBar\*(Aq])
.Ve
.PP
will result in two triples, one for each \f(CW\*(C`rdfs:label\*(C'\fR.
