OWL 2 DL ontology for a few terms of the DCMI abstract model from the http://purl.org/dc/dcam/ namespace OWL 2 DL ontology for the Dublin Core type vocabulary from the http://purl.org/dc/dcmitype/ namespace DCMI Abstract Model DCMI Type Vocabulary The range of skos:altLabel is the class of RDF plain literals. skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties. alternative label An alternative lexical label for a resource. Acronyms, abbreviations, spelling variants, and irregular plural/singular forms may be included among the alternative labels for a concept. Mis-spelled terms are normally included as hidden labels (see skos:hiddenLabel). change note A note about a modification to a concept. definition A statement or formal explanation of the meaning of a concept. editorial note A note for an editor, translator or maintainer of the vocabulary. example An example of the use of a concept. The range of skos:hiddenLabel is the class of RDF plain literals. skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties. hidden label A lexical label for a resource that should be hidden when generating visual displays of the resource, but should still be accessible to free text search operations. history note A note about the past state/use/meaning of a concept. note A general note, for any purpose. This property may be used directly, or as a super-property for more specific note types. A resource has no more than one value of skos:prefLabel per language tag, and no more than one value of skos:prefLabel without language tag. The range of skos:prefLabel is the class of RDF plain literals. skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties. preferred label The preferred lexical label for a resource, in a given language. scope note A note that helps to clarify the meaning and/or the use of a concept. Member Of A relationship between a resource and a vocabulary encoding scheme which indicates that the resource is a member of a set. has broader match skos:broadMatch is used to state a hierarchical mapping link between two conceptual resources in different concept schemes. Broader concepts are typically rendered as parents in a concept hierarchy (tree). has broader Relates a concept to a concept that is more general in meaning. By convention, skos:broader is only used to assert an immediate (i.e. direct) hierarchical link between two conceptual resources. has broader transitive skos:broaderTransitive is a transitive superproperty of skos:broader. By convention, skos:broaderTransitive is not used to make assertions. Rather, the properties can be used to draw inferences about the transitive closure of the hierarchical relation, which is useful e.g. when implementing a simple query expansion algorithm in a search application. has close match skos:closeMatch is used to link two concepts that are sufficiently similar that they can be used interchangeably in some information retrieval applications. In order to avoid the possibility of "compound errors" when combining mappings across more than two concept schemes, skos:closeMatch is not declared to be a transitive property. skos:exactMatch is disjoint with each of the properties skos:broadMatch and skos:relatedMatch. has exact match skos:exactMatch is used to link two concepts, indicating a high degree of confidence that the concepts can be used interchangeably across a wide range of information retrieval applications. skos:exactMatch is a transitive property, and is a sub-property of skos:closeMatch. has top concept Relates, by convention, a concept scheme to a concept which is topmost in the broader/narrower concept hierarchies for that scheme, providing an entry point to these hierarchies. is in scheme Relates a resource (for example a concept) to a concept scheme in which it is included. A concept may be a member of more than one concept scheme. These concept mapping relations mirror semantic relations, and the data model defined below is similar (with the exception of skos:exactMatch) to the data model defined for semantic relations. A distinct vocabulary is provided for concept mapping relations, to provide a convenient way to differentiate links within a concept scheme from links between concept schemes. However, this pattern of usage is not a formal requirement of the SKOS data model, and relies on informal definitions of best practice. is in mapping relation with Relates two concepts coming, by convention, from different schemes, and that have comparable meanings has member Relates a collection to one of its members. For any resource, every item in the list given as the value of the skos:memberList property is also a value of the skos:member property. has member list Relates an ordered collection to the RDF list containing its members. has narrower match skos:narrowMatch is used to state a hierarchical mapping link between two conceptual resources in different concept schemes. Narrower concepts are typically rendered as children in a concept hierarchy (tree). has narrower Relates a concept to a concept that is more specific in meaning. By convention, skos:broader is only used to assert an immediate (i.e. direct) hierarchical link between two conceptual resources. has narrower transitive skos:narrowerTransitive is a transitive superproperty of skos:narrower. By convention, skos:narrowerTransitive is not used to make assertions. Rather, the properties can be used to draw inferences about the transitive closure of the hierarchical relation, which is useful e.g. when implementing a simple query expansion algorithm in a search application. skos:related is disjoint with skos:broaderTransitive has related Relates a concept to a concept with which there is an associative semantic relationship. has related match skos:relatedMatch is used to state an associative mapping link between two conceptual resources in different concept schemes. is in semantic relation with Links a concept to a concept related by meaning. This property should not be used directly, but as a super-property for all properties denoting a relationship of meaning between concepts. is top concept in scheme Relates a concept to the concept scheme that it is a top level concept of. notation A notation, also known as classification code, is a string of characters such as "T58.5" or "303.4833" used to uniquely identify a concept within the scope of a given concept scheme. By convention, skos:notation is used with a typed literal in the object position of the triple. dcam:VocabularyEncodingScheme Vocabulary Encoding Scheme An enumerated set of resources. owl:Thing skos:Collection Collection A meaningful collection of concepts. Labelled collections can be used where you would like a set of concepts to be displayed under a 'node label' in the hierarchy. skos:Concept Concept An idea or notion; a unit of thought. skos:ConceptScheme Concept Scheme A set of concepts, optionally including statements about semantic relationships between those concepts. Thesauri, classification schemes, subject heading lists, taxonomies, 'folksonomies', and other types of controlled vocabulary are all examples of concept schemes. Concept schemes are also embedded in glossaries and terminologies. A concept scheme may be defined to include concepts from different sources. skos:OrderedCollection Ordered Collection An ordered collection of concepts, where both the grouping and the ordering are meaningful. Ordered collections can be used where you would like a set of concepts to be displayed in a specific order, and optionally under a 'node label'. OWL 2 DL ontology for a few terms of the DCMI abstract model from the http://purl.org/dc/dcam/ namespace DCMI Abstract Model OWL 2 DL ontology for the Dublin Core type vocabulary from the http://purl.org/dc/dcmitype/ namespace DCMI Type Vocabulary A collection is described as a group; its parts may also be separately described. Collection An aggregation of resources. Examples include lists, tables, and databases. A dataset may be useful for direct machine processing. Dataset Data encoded in a defined structure. Metadata for an event provides descriptive information that is the basis for discovery of the purpose, location, duration, and responsible agents associated with an event. Examples include an exhibition, webcast, conference, workshop, open day, performance, battle, trial, wedding, tea party, conflagration. Event A non-persistent, time-based occurrence. Examples include images and photographs of physical objects, paintings, prints, drawings, other images and graphics, animations and moving pictures, film, diagrams, maps, musical notation. Note that Image may include both electronic and physical representations. Image A visual representation other than text. Examples include forms on Web pages, applets, multimedia learning objects, chat services, or virtual reality environments. Interactive Resource A resource requiring interaction from the user to be understood, executed, or experienced. Examples include animations, movies, television programs, videos, zoetropes, or visual output from a simulation. Instances of the type Moving Image must also be describable as instances of the broader type Image. Moving Image A series of visual representations imparting an impression of motion when shown in succession. Note that digital representations of, or surrogates for, these objects should use Image, Text or one of the other types. Physical Object An inanimate, three-dimensional object or substance. Examples include a photocopying service, a banking service, an authentication service, interlibrary loans, a Z39.50 or Web server. Service A system that provides one or more functions. Examples include a C source file, MS-Windows .exe executable, or Perl script. Software A computer program in source or compiled form. Examples include a music playback file format, an audio compact disc, and recorded speech or sounds. Sound A resource primarily intended to be heard. Examples include paintings, drawings, graphic designs, plans and maps. Recommended best practice is to assign the type Text to images of textual materials. Instances of the type Still Image must also be describable as instances of the broader type Image. Still Image A static visual representation. Examples include books, letters, dissertations, poems, newspapers, articles, archives of mailing lists. Note that facsimiles or images of texts are still of the genre Text. Text A resource consisting primarily of words for reading.
