Several common [[Serialization|serialization formats]] are in use, including:
* '''[[Turtle (syntax)|Turtle]],'''<ref name="turtle">{{cite web
  |title=RDF 1.1 Turtle: Terse RDF Triple Language
  |url=http://www.w3.org/TR/turtle/
  |date=9 January 2014
  |publisher=W3C
}}</ref> a compact, human-friendly format.
* '''[[TriG (syntax)|TriG]],'''<ref name="trig">{{cite web
  |title=RDF 1.1 TriG: RDF Dataset Language
  |url=http://www.w3.org/TR/trig/
  |date=25 February 2014
  |publisher=W3C
}}</ref> an extension of Turtle to datasets.
* '''[[N-Triples]],'''<ref name="n-triples" >{{cite web
  |title=RDF 1.1 N-Triples: A line-based syntax for an RDF graph
  |date=9 January 2014
  |url=http://www.w3.org/TR/n-triples/
  |publisher=[[W3C]]
}}</ref> a very simple, easy-to-parse, line-based format that is not as compact as Turtle.
* '''[[N-Quads]],'''<ref>{{cite web

* '''[[JSON-LD]],'''<ref name="json-ld">{{cite web|title=JSON-LD 1.0: A JSON-based Serialization for Linked Data|url=http://www.w3.org/TR/json-ld/|publisher=W3C}}</ref> a [[JSON]]-based serialization.
* '''N3''' or [[Notation3]], a non-standard serialization that is very similar to Turtle, but has some additional features, such as the ability to define inference rules.
* '''[[RDF/XML]]''',<ref name="rdf-xml" >{{cite web

* '''RDF/JSON''',<ref name="rdf-json" >{{cite web
  |title=RDF 1.1 JSON Alternate Serialization (RDF/JSON)
  |date=7 November 2013
  |url=https://www.w3.org/TR/rdf-json/
  |publisher=[[W3C]]
}}</ref> an alternative syntax for expressing RDF triples using a simple JSON notation.

RDF/XML is sometimes misleadingly called simply RDF because it was introduced among the other W3C specifications defining RDF and it was historically the first W3C standard RDF serialization format. However, it is important to distinguish the RDF/XML format from the abstract RDF model itself. Although the RDF/XML format is still in use, other RDF serializations are now preferred by many RDF users, both because they are more human-friendly,<ref name="rdf-xml-syntax-criticism">{{cite web|title=Problems of the RDF syntax|url=http://milicicvuk.com/blog/2011/07/21/problems-of-the-rdf-syntax/|publisher=Vuk Miličić}}</ref>  and because some RDF graphs are not representable in RDF/XML due to restrictions on the syntax of XML [[QName]]s.

With a little effort, virtually any arbitrary [[XML]] may also be interpreted as RDF using [[GRDDL]] (pronounced 'griddle'), Gleaning Resource Descriptions from Dialects of Languages.

RDF triples may be stored in a type of database called a [[triplestore]].
