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

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?
