Editing Resource Description Framework (section)

=== Example 2: The postal abbreviation for New York ===

Certain concepts in RDF are taken from [[logic]] and [[linguistics]], where subject-predicate and subject-predicate-object structures have meanings similar to, yet distinct from, the uses of those terms in RDF. This example demonstrates:

In the [[English language]] statement '' 'New York has the postal abbreviation NY' '','' 'New York' '' would be the subject, '' 'has the postal abbreviation' '' the predicate and '' 'NY' '' the object.

Encoded as an RDF triple, the subject and predicate would have to be resources named by URIs. The object could be a resource or literal element. For example, in the N-Triples form of RDF, the statement might look like:

<syntaxhighlight lang="turtle">
<urn:x-states:New%20York> <http://purl.org/dc/terms/alternative> "NY" .
</syntaxhighlight>

In this example, "<nowiki>urn:x-states:New%20York</nowiki>" is the URI for a resource that denotes the US state [[New York (state)|New York]], "<nowiki>http://purl.org/dc/terms/alternative</nowiki>" is the URI for a predicate (whose human-readable definition can be found here<ref>[https://www.dublincore.org/specifications/dublin-core/dcmi-terms/terms/alternative/ DCMI Metadata Term alternative]. Dublincore.org. Retrieved on 2022-01-10.</ref>), and "NY" is a literal string.  Note that the URIs chosen here are not standard, and do not need to be, as long as their meaning is known to whatever is reading them.
