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