Because variables are 'keyed' -by URI (the predicate), future extensions can define variables with -specific meanings or restricted/extended types. -The value (rdf:value) of a variable may be anything, but hosts or plugins -aren't guaranteed to support anything other than simple typed literals. -Serialisation and code access to complex variables is considered outside -the scope of this extension. - -Hosts and plugins SHOULD use the following types for appropriate values: - -<table> -<tr><th>RDF Type</th><th>Data Type</th></tr> -<tr><td>xsd:string</td><td>string</td></tr> -<tr><td>xsd:decimal</td><td>floating point number</td></tr> -<tr><td>xsd:integer</td><td>integer number</td></tr> -<tr><td>xsd:boolean</td><td>boolean value</td></tr> -</table> - -This extension does not currently define a code mechanism for access -to variables.
