Abstract

The Nepomuk User Action Ontology defines provides basic classes and properties for user events on a device.

Status of this document

This document arose from the work in KDE, acting upon the work done by Task-Force ontologies within the NEPOMUK project.

Ontology Classes Description

DesktopEvent

Superclasses nuao:Event, rdfs:Resource
Subclasses ndo:DownloadEvent, nuao:FocusEvent, nuao:ModificationEvent, nuao:UsageEvent
In domain of: --
In range of: --
Description A desktop event: activity performed by an user. A "hook" class that should be extended by other ontologies such as desktop service ontology to specify which application or service was involved in the desktop event.

Event

Superclasses rdfs:Resource
Subclasses nuao:DesktopEvent, ndo:DownloadEvent, nuao:FocusEvent, nuao:ModificationEvent, nuao:UsageEvent
In domain of: nuao:duration, nuao:end, nuao:initiatingAgent, nuao:involves, nuao:start, nuao:targettedResource
In range of: --
Description An event: activity that have a specific start datetime and possibly a duration

FocusEvent

Superclasses nuao:DesktopEvent, nuao:Event, rdfs:Resource
Subclasses --
In domain of: --
In range of: --
Description An event which refers to the timespan in which a resource was in the focus of the user.

ModificationEvent

Superclasses nuao:DesktopEvent, nuao:Event, rdfs:Resource
Subclasses --
In domain of: --
In range of: --
Description An event that lead to changes of the resource that are meaningful to the user

UsageEvent

Superclasses nuao:DesktopEvent, nuao:Event, rdfs:Resource
Subclasses --
In domain of: --
In range of: --
Description An event of primary or intended use of the resource by the user. Primary or intended use is defined as the use by the consumer of the resource, such as watching a movie or listening to a song. Not to be confused with a low-level read on a file.
