Library Ontology Concepts

This page collects some concepts (classes and properties) of the Library Ontology. To refer to other ontolgies the following namespace prefixes are defined (all in Turtle syntax):

# RDF basics
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix owl: <http://www.w3.org/2002/07/owl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix ns: <http://www.w3.org/2003/06/sw-vocab-status/ns#> .

# Other Ontologies
@prefix dct:  <http://purl.org/dc/terms/> .
@prefix dc:   <http://purl.org/dc/elements/1.1/> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix event: <http://purl.org/NET/c4dm/event.owl#> .
@prefix skos: <http://www.w3.org/2008/05/skos#> .
@prefix bibo: <http://purl.org/ontology/bibo/> .
@prefix daia: <http://purl.org/ontology/daia/> .
@prefix geo: <http://www.w3.org/2003/01/geo/wgs84_pos#> .
@prefix frbr: <http://purl.org/vocab/frbr/core#> .
@prefix vcard: <http://www.w3.org/2006/vcard/ns#> .
@prefix address: <http://schemas.talis.com/2005/address/schema#> .
@prefix mods: <http://www.loc.gov/mods/v3> . # experimental - MODS is not RDF but parts of it can be used

In addition mfc: refers to the MARC 21 Format for Community Information which is not an ontology at all - but at least you can point to some existing MARC fields. For instance mfc:270$k is the telephone number (which can better be expressed as vcard:tel in RDF). In the same way zeta: refers to the ZETA cataloging format in PICA+ which is used by the German Sigelverzeichnis (see their rules). For instance the telephone number is zeta:035B$a.

Classes

Library

A library can be a collection, an organization, or a place.

:Library rdf:type owl:Class ;
    rdfs:subClassOf [ 
        rdf:type owl:Class ;
        owl:unionOf ( bibo:Collection foaf:Organization geo:SpatialThing )
    ] .

:LibraryBuilding rdf:type owl:Class ;
    rdfs:subClassOf :Library , geo:SpatialThing  ;
    owl:intersectionOf ( :Library , geo:SpatialThing ) .

:LibraryOrganization rdf:type owl:Class ;
    rdfs:subClassOf :Library , foaf:Organization ;
    owl:intersectionOf ( :Library , foaf:Organization ) .

:LibraryCollection rdf:type owl:Class ;
    rdfs:subClassOf :Library , bibo:Collection .
    owl:intersectionOf ( :Library , bibo:Collection ) .

Addresses

The Library Ontology does not define address classes and properties because there already is vCard.

Library Services

See DAIA (see http://purl.org/ontology/daia/ and some notes)

Other concepts

holding, store, stack, loan...

Properties

FRBR simplified

libo:exemplar can link a work, expression or manifestation to an item
libo:exemplarOf implies beeing a frbr:item but nothing less

Identifiers

:isil rdf:type owl:DatatypeProperty ;
    rdfs:subClassOf dct:identifier .

There is an authority file for libraries amnd similar organisations as Linked Data: lobid-organisations

Relationships between Libraries and their collections

owns ?
holds ?
provides ?

Relationships between Libraries

Libraries can be and have subordinate entities which do not need to be libraries. Libraries can split and join. Libraries can be friends ;-)

dct:hasPart/dct:isPartOf
foaf:knows
branch? subunit? partner?
