a link predicate

• Property

class

The rdfs:Class that is the rdf:type of all entities in a class-based partition.

• FunctionalProperty
• Property

class partition

A subset of a void:Dataset that contains only the entities of a certain rdfs:Class.

• Property

classes

The total number of distinct classes in a void:Dataset. In other words, the number of distinct resources occuring as objects of rdf:type triples in the dataset.

• DatatypeProperty
• Property

Data Dump

An RDF dump, partial or complete, of a void:Dataset.

• Property

dataset

A set of RDF triples that are published, maintained or aggregated by a single provider.

• Class
• Class

dataset description

A web resource whose foaf:primaryTopic or foaf:topics include void:Datasets.

• Class
• Class

distinct objects

The total number of distinct objects in a void:Dataset. In other words, the number of distinct resources that occur in the object position of triples in the dataset. Literals are included in this count.

• DatatypeProperty
• Property

distinct subjects

The total number of distinct subjects in a void:Dataset. In other words, the number of distinct resources that occur in the subject position of triples in the dataset.

• DatatypeProperty
• Property

example resource of dataset

• Property

feature

• Property

has URI regular expression pattern

Defines a regular expression pattern matching URIs in the dataset.

• Property

has a SPARQL endpoint at

• Property

has an URI look-up endpoint at

Defines a simple URI look-up protocol for accessing a dataset.

• Property

has subset

• Property

in dataset

Points to the void:Dataset that a document is a part of.

• Property

linkset

A collection of RDF links between two void:Datasets.

• Class
• Class

number of documents

The total number of documents, for datasets that are published as a set of individual documents, such as RDF/XML documents or RDFa-annotated web pages. Non-RDF documents, such as web pages in HTML or images, are usually not included in this count. This property is intended for datasets where the total number of triples or entities is hard to determine. void:triples or void:entities should be preferred where practical.

• DatatypeProperty
• Property

number of entities

The total number of entities that are described in a void:Dataset.

• DatatypeProperty
• Property

number of properties

The total number of distinct properties in a void:Dataset. In other words, the number of distinct resources that occur in the predicate position of triples in the dataset.

• DatatypeProperty
• Property

number of triples

The total number of triples contained in a void:Dataset.

• DatatypeProperty
• Property

Objects Target

The dataset describing the objects of the triples contained in the Linkset.

• FunctionalProperty
• Property

open search description

An OpenSearch description document for a free-text search service over a void:Dataset.

• Property

property

The rdf:Property that is the predicate of all triples in a property-based partition.

• FunctionalProperty
• Property

property partition

A subset of a void:Dataset that contains only the triples of a certain rdf:Property.

• Property

root resource

A top concept or entry point for a void:Dataset that is structured in a tree-like fashion. All resources in a dataset can be reached by following links from its root resources in a small number of steps.

• Property

Subjects Target

The dataset describing the subjects of triples contained in the Linkset.

• FunctionalProperty
• Property

Target

One of the two datasets linked by the Linkset.

• Property

technical feature

A technical feature of a void:Dataset, such as a supported RDF serialization format.

• Class
• Class

URI space

A URI that is a common string prefix of all the entity URIs in a void:Dataset.

• DatatypeProperty
• Property

vocabulary

A vocabulary that is used in the dataset.

• Property

Vocabulary of Interlinked Datasets (VoID)

The Vocabulary of Interlinked Datasets (VoID) is an RDF Schema vocabulary for expressing metadata about RDF datasets. It is intended as a bridge between the publishers and users of RDF data, with applications ranging from data discovery to cataloging and archiving of datasets. This document provides a formal definition of the new RDF classes and properties introduced for VoID. It is a companion to the main specification document for VoID, <em><a href="http://www.w3.org/TR/void/">Describing Linked Datasets with the VoID Vocabulary</a></em>.
