+title: Support of RDF-star
+slug: index
+aliases:
+    - /docimentation/rdfstar/

+---
+
+[RDF-star](https://w3c.github.io/rdf-star/) is an extension to RDF that provides
+a way for one triple to refer to another triple. RDF\* is the name of the
+original work which is described in
+[Olaf Hartig's blog entry](https://blog.liu.se/olafhartig/2019/01/10/position-statement-rdf-star-and-sparql-star/).
+
+Example:
+
+```turtle
+<< :john foaf:name "John Smith" >> dct:source <http://example/directory> .
+```
+
+The part `<< :john foaf:name "John Smith" >>` is an embedded triple and refers to the triple with subject `:john`, property `foaf:name` and object `"John Smith"`.
+
+Triple terms can be in the subject or object position.
+
+Jena provides support for RDF-star and the related SPARQL-star.
+
+* Turtle, N-Triples, TriG and N-Quads extended for Triple Terms syntax,
+  input and outout.  There is no output in RDF/XML.
