Defines a simple URI look-up protocol for accessing a dataset. has an URI look-up endpoint at has a SPARQL endpoint at feature 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. 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. The total number of entities that are described in a void:Dataset. number of entities 2011-03-06 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>. http://rdfs.org/ns/void# 2010-01-26 void Vocabulary of Interlinked Datasets (VoID) http://vocab.deri.ie/void#Digital%20Enterprise%20Research%20Institute%2C%20NUI%20Galway Jun Zhao A technical feature of a void:Dataset, such as a supported RDF serialization format. technical feature The dataset describing the objects of the triples contained in the Linkset. Objects Target Richard Cyganiak 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. An RDF dump, partial or complete, of a void:Dataset. Data Dump example resource of dataset Subjects Target The dataset describing the subjects of triples contained in the Linkset. 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. LiDRC 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. property The rdf:Property that is the predicate of all triples in a property-based partition. An OpenSearch description document for a free-text search service over a void:Dataset. open search description A web resource whose foaf:primaryTopic or foaf:topics include void:Datasets. dataset description 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. Department of Zoology, University of Oxford Keith Alexander Digital Enterprise Research Institute, NUI Galway One of the two datasets linked by the Linkset. Target vocabulary A vocabulary that is used in the dataset. Michael Hausenblas property partition A subset of a void:Dataset that contains only the triples of a certain rdf:Property. http://vocab.deri.ie/void.rdf in dataset Points to the void:Dataset that a document is a part of. has URI regular expression pattern Defines a regular expression pattern matching URIs in the dataset. class The rdfs:Class that is the rdf:type of all entities in a class-based partition. has subset http://vocab.deri.ie/void.ttl A collection of RDF links between two void:Datasets. linkset class partition A subset of a void:Dataset that contains only the entities of a certain rdfs:Class. A URI that is a common string prefix of all the entity URIs in a void:Dataset. URI space a link predicate number of triples The total number of triples contained in a void:Dataset. Talis dataset A set of RDF triples that are published, maintained or aggregated by a single provider.
