arc

From Resource Description Framework (RDF) Model and Syntax Specification (1999-02-22)

A representation of a property in a graph form; specifically the edges in a directed labeled graph.

attribute

From Resource Description Framework (RDF) Model and Syntax Specification (1999-02-22)

A characteristic of an object. In Chapter 6 this term refers to a specific XML syntactic construct; the name="value" portions of an XML tag.

element

From Resource Description Framework (RDF) Model and Syntax Specification (1999-02-22)

As used here, this term refers to a specific XML syntactic construct; i.e., the material between matching XML start and end tags.

literal

From Resource Description Framework (RDF) Model and Syntax Specification (1999-02-22)

The most primitive value type represented in RDF, typically a string of characters. The content of a literal is not interpreted by RDF itself and may contain additional XML markup. Literals are distinguished from Resources in that the RDF model does not permit literals to be the subject of a statement.

node

From Resource Description Framework (RDF) Model and Syntax Specification (1999-02-22)

A representation of a resource or a literal in a graph form; specifically, a vertex in a directed labeled graph.

property

From Resource Description Framework (RDF) Model and Syntax Specification (1999-02-22)

A specific attribute with defined meaning that may be used to describe other resources. A property plus the value of that property for a specific resource is a statement about that resource. A property may define its permitted values as well as the types of resources that may be described with this property.

resource

From Resource Description Framework (RDF) Model and Syntax Specification (1999-02-22)

An abstract object that represents either a physical object such as a person or a book or a conceptual object such as a color or the class of things that have colors. Web pages are usually considered to be physical objects, but the distinction between physical and conceptual or abstract objects is not important to RDF. A resource can also be a component of a larger object; for example, a resource can represent a specific person's left hand or a specific paragraph out of a document. As used in this specification, the term resource refers to the whole of an object if the URI does not contain a fragment (anchor) id or to the specific subunit named by the fragment or anchor id.

statement

From Resource Description Framework (RDF) Model and Syntax Specification (1999-02-22)

An expression following a specified grammar that names a specific resource, a specific property (attribute), and gives the value of that property for that resource. More specifically here, an RDF statement is a statement using the RDF/XML grammar specified in this document.

triple

From Resource Description Framework (RDF) Model and Syntax Specification (1999-02-22)

A representation of a statement used by RDF, consisting of just the property, the resource identifier, and the property value in that order.
