rdfs:Class 2. rdfs:Resource 2. It is not normative for many aspects of RDF meaning which are not described or specified rdfs:seeAlso bdr:T123 bdr:T1129 ) Note that, in OWL 2, rdfs:seeAlso is defined as an annotation property, so the original assertion (bdr:T123 rdfs:seeAlso bdr:T1129) is itself an annotation When such representations may be retrieved, no constraints are placed on the format of those representations. rdf:Property 2. Using HTTP URIs ensures that anybody can look up the resource. rdfs:seeAlso 2. 5. This section describes the status of this document at the time of its publication. r. rdfs:label a human-readable name for the subject rdfs:comment a description of the subject resource rdfs:member a member of the subject resource rdfs:seeAlso further information about the subject The example implicitly derives that ex: frank also belongs to the ex: Person class because ex: hasMother belongs to the ex: Person class. rdf:type 2. :validate rdfs:seeAlso (IRI1 IRI2 ) . 4. As a standard, RDFS provides language constructs that can be used to describe classes and properties within a rdfs:comment "The class of RDF containers. the . " . This specification describes how to use RDF to describe RDF Abstract The SIOC (Semantically-Interlinked Online Communities) Core Ontology provides the main concepts and properties required to describe information from online communities This document is most recent version. An HTTP URI of a resource can be dereferenced: use an HTTP client to retrieve a Documentation, backgrounders and tutorial material related to information design, engineering, semantics, ontologies, and vocabularies However, some believe that rdfs:seeAlso should only point to RDF data of limited size, in particular because of how it is used in the FOAF project and the Tabulator data browser. the rdf data model l Terms for classes –rdfs:ContainerMem- bershipProperty lSpecial properties –rdfs:comment –rdfs:seeAlso –rdfs:isDefinedBy –rdfs:label RDFS introduces the following terms, giving each a meaning w. Example Abbreviated Since an RDFS class is an RDF resource we can abbreviate the example above by using rdfs:Class instead of rdf:Description, and drop the rdf:type information: RDF Schema (RDFS) enriches the data model, adding vocabulary &associated semantics for Classes and subclasses RDFS grants you terminology to talk about classes and the class hierarchy, as demonstrated here: We see that rdfs:subClassOf is defined by RDFS, but that the raw class Abstract The Resource Description Framework (RDF) is a general-purpose language for representing information in the Web. When you want to be very clear in markup that you are using an rdfs:seeAlso property to reference a document that is available in RDF/XML format, it is possible to do this using additional The rdfs:seeAlso relationship is intended to support some hypertext links between RDF documents on the web. 3. t. It provides mechanisms for describing groups of related resources and the relationships In Linked Data, it can be used to do just what it says, and a hypothetical linked data client might dereference IRI values of rdfs:seeAlso to find out more information that might be useful. resources and properties are used to define modeling primitives of RDF Schema (RDF itself is used!) rdfs:seeAlso is an instance of rdf:Property that is used to indicate a resource that might provide additional information about the subject resource. We will refer to entailment regimes by names such as RDFS entailment, D-entailment, etc. rdf:Propertyのインスタンス ドメイン It uses seeAlso reference (1) for making a reference from a general or broader term to a more specific or narrower one; for example, mathematics SA Arithmetic, and (2) for referencing related or associated RDF Schema is an extension of the basic RDF vocabulary. The rdfs:domain of RDFS semantics based on inference rules Semantics in terms a rule system instead of restating RDF in terms of first-order logic Rule system consists of inference rules of the form: Core Classes 2. When reading an RDF file, it should process triples of the forms: :transform rdfs:seeAlso (IRI1 IRI2 ) . This specification, RDF 1. There are no explicit semantics for the property other than that a user agent might expect to For example, the object wd: Q483501 is a statement defined by Wikidata. 2 Semantics, is normative for RDF semantics and the validity of RDF inference processes. The model uses the predicate rdfs: seeAlso to link and associate Artist RDF Schema is a semantic extension of RDF. rdfs:Datatype is the class of With this definition, RDFS can be understood as RDF’s vocabulary description language. To deduce that the value of an instance RDFS, described later in this document, is one such semantic extension. 2. This should add the IRIs to the list of RDF files to be A is a subclass of B if every instance of A is also an instance of B ! then B is a superclass of A. property values such as textual strings are examples of RDF literals. rdfs:isDefinedBy is a subproperty of rdfs:seeAlso. rdfs:subPropertyOf 2. rdfs:ContainerMembershipProperty a rdfs:Class ; rdfs:isDefinedBy <http://www. rdfs:Class rdf:type rdfs:Class The other classes described by the RDF and RDFS specifications rdfs:Literal is the class of literal values such as strings and integers. 1. Furthermore, The couple RDF and RDFS is also reused in several other activities of W3C, for example, in the Semantic Web Activities, as de facto standard for metadata, and as provider of the fundamental layer It's through the use of the rdfs:seeAlso property that FOAF can be used to build a web of machine-processable metadata; rdfs:seeAlso is to RDF what the anchor element is to HTML. A list RDF Schema (RDFS) enriches the data model, adding vocabulary &associated semantics for Classes and subclasses all schema information in RDFS is defined with RDF triples 4# and RDF Schema basic ideas - example a construct to specify a set in RDFS is rdfs:Class since RDFS is expressed in RDF – then in a triple The definition of rdfs:Class is recursive: rdfs:Class is the class of classes, and so it is an instance of itself. org/2000/01/rdf-schema#> ; rdfs:label Cardinality constraints for property domains/ranges (as well as inverse properties and Boolean class expressions) can be captured in more expressive ontology languages such as OWL. Core Properties 2. rdfs:subClassOf 2. Literals may be plain or typed. w3. Other examples of RDFS Vocabulary RDFS introduces the following terms, giving each a meaning w.
