    vann:preferredNamespacePrefix "mwo" .

2 Classes

2.1 DocumentService

A DocumentService is a service event that is related to one or more documents. The service event involves a service provider (e.g.a library) and an optional service consumer (e.g. a library patron). Both service provider and service consumer SHOULD be instances of foaf:Agent. The DocumentService class is defined by the Document Service Ontology.

dso:DocumentService a owl:Class ;
    rdfs:label "DocumentService" ;
    rdfs:isDefinedBy <http://purl.org/ontology/dso> .

Typical document services within the scope of holdings ontology involve a loan event (dso:Loan) and a presentation event (dso:Presentation). To express the availability of items for selected services, one SHOULD use the properties daia:availableFor and daia:unavailableFor from the DAIA Ontology.

3 Properties

3.1 numVolumes

The number of volumes that are included in or excluded from the DocumentService. The number MUST be of the datatype xsd:integer and thus can be positive or negative.

mwo:numVolumes a owl:DatatypeProperty ;
    rdfs:label "number of volumes" ;
    rdfs:comment "The number of volumes that are included in or excluded from the DocumentService." ;
    rdfs:domain dso:DocumentService ;
    rdfs:range xsd:integer .

3.2 numIssues

The number of issues that are included in or excluded from the DocumentService. The number MUST be of the datatype xsd:integer and thus can be positive or negative.

mwo:numIssues a owl:DatatypeProperty ;
    rdfs:label "number of issues" ;
    rdfs:comment "The number of issues that are included in or excluded from the DocumentService." ;
    rdfs:domain dso:DocumentService ;
    rdfs:range xsd:integer .

3.3 time

A part of the document expressed through a period of time which is excluded from the DocumentService. The period MUST be of the datatype xsd:duration and thus can be positive or negative.

mwo:excludedTime a owl:DatatypeProperty ;
    rdfs:label "excluded time" ;
    rdfs:comment "A part of the document expressed through a period of time which is excluded from the DocumentService." ;
    rdfs:domain dso:DocumentService ;
    rdfs:range xsd:duration .
