Abstract
The PIMO Ontology can be used to express Personal Information Models of individuals. It is based on RDF and NRL, the NEPOMUK Representational Language and other Semantic Web ontologies. This document describes the principle elements of the language and how to use them.
Status of this document
This section describes the status of this document at the time of its publication. The form used for this status message and document is inspired by the W3C process.
This document describes an OSCAF ontology recommendation describing an ontology for Personal Information Models (PIMO). It was edited first within the NEPOMUK project and is now maintained by OSCAF members. The listed editor is responsible to bring in feedback from the other authors, contributors, and the community at large. This document and the PIMO ontology as such is based on various other publications by the authors, and is a continuation of existing work. Other documents may supersede this document. Parts of this document will be published in other documents, such as scientific publications.
This recommendation is accompanied by a RDFS/NRL ontology, which is the authorative formal description of the ontology.
Additional to this document, a PIMO FAQ is maintained and a detailled PIMO information page.

Ontology Classes Description
Agent
| Superclasses | pimo:ClassOrThing, pimo:ClassOrThingOrPropertyOrAssociation, rdfs:Resource, pimo:Thing |

| Description | An agent (eg. person, group, software or physical artifact). The Agent class is the class of agents; things that do stuff. A well known sub-class is Person, representing people. Other kinds of agents include Organization and Group. (inspired by FOAF). Agent is not a subclass of NAO:Party. |
Association
| Superclasses | pimo:ClassOrThingOrPropertyOrAssociation, rdfs:Resource |

| Description | An association between two or more pimo-things. This is used to model n-ary relations and metadata about relations. For example, the asociation of a person being organizational member is only effectual within a period of time (after the person joined the organization and before the person left the organization). There can be multiple periods of time when associations are valid. |
Attendee
| Superclasses | pimo:Association, pimo:ClassOrThingOrPropertyOrAssociation, pimo:PersonRole, rdfs:Resource |

Collection

| Subclasses | pimo:PersonGroup, tmo:TaskContainer |
| In domain of: | -- |
| In range of: | -- |
| Description | A collection of Things, independent of their class. The items in the collection share a common property. Which property may be modelled explicitly or mentioned in the description of the Collection. The requirement of explicit modelling the semantic meaning of the collection is not mandatory, as collections can be created ad-hoc. Implizit modelling can be applied by the system by learning the properties. For example, a Collection of "Coworkers" could be defined as that all elements must be of class "Person" and have an attribute "work for the same Organization as the user". Further standards can be used to model these attributes. |

| Description | Short: hasOtherRepresentation points from a Class in your PIMO to a class in a domain ontology that represents the same class. Longer: hasOtherConceptualization means that a class of real world objects O represented by a concept C1 in the ontology has additional conceptualizations (as classes C2-Cn in different domain ontologies). This means: IF (O\_i is conceptialized by C\_j in Ontology\_k) AND (O\_l is conceptialized by C\_m in Ontology\_n) THEN (O\_i and O\_l is the same set of objects). hasOtherConceptualization is an transitive relation, but not equivalent (not symmetric nor reflexive). |

| Description | hasOtherRepresentation points from a Thing in your PIMO to a thing in an ontology that represents the same real world thing. This means that the real world object O represented by an instance I1 has additional representations (as instances I2-In of different conceptualizations). This means: IF (I\_i represents O\_j in Ontology\_k) AND (I\_m represents O\_n in Ontology\_o) THEN (O\_n and O\_j are the same object). hasOtherRepresentation is a transitive relation, but not equivalent (not symmetric nor reflexive). For example, the URI of a foaf:Person representation published on the web is a hasOtherRepresentation for the person. This property is inverse functional, two Things from two information models having the same hasOtherRepresentation are considered to be representations of the same entity from the real world. |
