Examples

Basic Examples

- MIME type: application/rdf+xml.
- XML-based format for RDF graphs.
- RDF/XML is specified at https://www.w3.org/TR/rdf-syntax-grammar/.

General Import elements:
"Elements" list of elements and options available in this file

"Rules" full list of rules for each element and option

"Options" list of rules for options, properties and settings
Data representation elements:
"Data" an RDFStore

"Base" base IRI used to resolve relative IRIs

"Prefixes" association of prefixes to namespace IRIs

Import options:
"Base" Automatic base IRI used to resolve relative IRIs
The value of "Base" is only used if the file does not specify a base IRI.
"Base" can take the following values:
Automatic the file name of the imported file

None no base IRI

"iri" or URL ["iri"] an IRI
Export options:
"Base" None produce IRIs relative to this base

"Prefixes" <||> produce prefixed names using these prefixes
"Base" and "Prefixes" can be used to shorten an exported file. These options do not change the meaning of the RDFStore that the file represents.

Wolfram Language code: Needs["GraphStore`"]

Export an RDF graph as RDF/XML:

Wolfram Language code:

g = RDFStore[{
	RDFTriple[URL["http://example.org/s"], URL["http://example.org/p"], "abc"]
	}];

Wolfram Language code: ExportString[g, "RDFXML", "Prefixes" -> <|"ex" -> "http://example.org/"|>]

Import the same document:

Wolfram Language code: ImportString[%, "RDFXML"]
