Personal Information Model (Ontology)

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.

Ontology:

• http://www.semanticdesktop.org/ontologies/2007/11/01/pimo# - pimo namespace and ontology

How to use Personal Information Models?

All you need to know is in this report:

• PIMO.pdf - documentation of PIMO (v1.1, NEPOMUK Recommendation).

Presentations

• SummerSchool: hands on PIMO Presentation of how to create personal information models written by LeoSauermann for the Nepomuk SummerSchool in 2008. 8.September 2008, Malta. This presentation includes N3 examples and a step-by-step introduction. It can be read in parallel to the PIMO.pdf report.
• Presentation at I-Semantics Conference by LeoSauermann, Graz, 6.September.2007
• Presentation at TF-Ont workshop by LeoSauermann, Karlsruhe, 15.August 2007

Examples: Claudia Stern's PIMO and teaching ontology

There is a PIMO for Claudia Stern (one of Nepomuk's personas) which you can find here:

• claudia.n3

It references some files and outlook elements from Claudia's Testdata:

• testdata/claudia_stern (non-public)

A small description of this scenario was developed by Gunnar (extensible :-)

• http://www.dfki.uni-kl.de/~grimnes/2007/10/GnowsisDemo/

There is a JUnit-Test which shows some features from the PimoService?. In this test we act like Claudia when she uses Nepomuk to build her Pimo.

The teaching ontology from the PIMO guide is here:

Development of the PIMO Ontology

The editor of PIMO is LeoSauermann, the process is described on [OntologyMaintenance#PIMOMaintenance]. When Leo reviews the tickets and does changes to the ontology and documentation, he does it like this:

edit the RDFS using a text editor, so that SVN diff documents the changes, here:

• https://oscaf.svn.sourceforge.net/svnroot/oscaf/trunk/ontologies/pimo/pimo.trig

edit the Latex (for example using TexnicCenter) here:

• https://oscaf.svn.sourceforge.net/svnroot/oscaf/trunk//ontologies/pimo/doc/handbook_latex/

Editing PIMO in the Protege Ontology Editor was possible but made it hard to track changes, so LeoSauermann switched to making changes using a plaintext editor for editing the ontology for better tracking of changes and documentation.

Mapping to NIE

When the user wants to have an information element like a contact which was crawled by Aperture as a pimo:Person to work with it, a new element in the pimo is created and has the information element as grounding occurrence. The problem comes up, what type the Pimo thing should have. For that reason there is a mapping from the Pimo types to possible types from the Nepomuk ontologies. This are often abstract types like NIE#InformationElement?.
