description: An ontology describing library and archive works, including their physical items and relationships.

Work
type: Class
comment: An individual work such as a text, archive item or picture; or a grouping of individual works (so, for instance, an archive collection counts as a work, as do all the series and individual files within it). Each work may exist in multiple instances (e.g. copies of the same book). N.B. this is not synonymous with "work" as that is understood in the International Federation of Library Associations and Institutions' Functional Requirements for Bibliographic Records model (FRBR) but represents something lower down the FRBR hierarchy, namely manifestation. Groups of related items are also included as works because they have similar properties to the individual ones.

Item
type: Class
comment: A specific instance of a work: for instance, an individual physical copy with its own location. This corresponds to the bottom, Instance, layer of FRBR. Works that are unique - that is, have only one copy - are described in terms of a Work for their intellectual content, linked to an Item describing their local (usually physical) characteristics.

type: ObjectProperty
comment: Relates the general bibliographic description of a work to specific instances of it, each item forming a unique incarnation of that work. Item here corresponds to the bottom layer of FRBR.
domain: Work
range: Item

isPartOf
type: ObjectProperty
comment: Relates an work to its host work.
domain: Work
range: Work

domain: Work
range: Work
is defined by: Works ontology

copyOf
type: ObjectProperty
comment: Relates an entity to one of which it forms a copy - that is, a transcription or other duplication. (This property is used when it results in the creation of a new bibliographic entity and not simply for second instances of a particular work.)
domain: Work
range: Work
is defined by: Works ontology

originalOf
type: ObjectProperty
comment: Relates an entity to one that forms a copy of it. (This property is used when it results in the creation of a new bibliographic entity and not simply for second instances of a particular work.)
domain: Work
range: Work
is defined by: Works ontology

creators
type: ObjectProperty
comment: Relates a work to its author, compiler, editor, artist or other entity responsible for its coming into existence in the form that it has.
domain: Work
range: Agent
is defined by: Works ontology

type: ObjectProperty
comment: Relates a work to its place of publication.
domain: Work
range: Place
is defined by: Works ontology

placeOfCreation
type: ObjectProperty
comment: Relates a work to its place of creation; typically this will be used for unpublished works, whilst published works will instead use the property hasPublicationLocation.

is defined by: Works ontology

subjects
type: ObjectProperty
comment: Relates a work to the general thesaurus-based concept that describes the work's content.

workType
type: ObjectProperty
comment: Relates a Work to the general WorkType that describes the work's form: published text, painting, and so on.
domain: Work
range: WorkType
is defined by: Works ontology

publicationDate
type: DatatypeProperty
comment: Relates the publication of a work to a date, when the work has been formally published. This date is not identical with the property createdDate: for example, a work may be created at a particular time but only published after the author's death, or a work may be published in a modern edition long after first publication. An extreme example would be the works of Aristotle, all of which are created some centuries BCE but not published in the formal sense for many centuries after this
