## Overview

### Introduction

This is the ontology modelling contacts and postal addresses. It also extends the original nepomuk adding the Instant Messaging account details, because an 'identity' in an IM account can be consider also a contact.

FIXME This documentation must be completed.

### A contact in this ontology

Document here how a contact with work and personal details is represented in the ontology. So far the QtContacts API is using this model to store the information internally, document here all the assumptions they are doing in the code, so a client using pure Sparql is completely compatible with that information

Do not forget contact groups and affiliations

### Postal Address

Postal address class nco:PostalAddress represents a point in the space defined by the usual street, number, postal code textual data. Most of its parameters come from the RFC 2426 section 3.2.1 with few extensions for more granular APIs (nco:county and nco:district)

### IM Accounts and contacts

Explain here how to represent the accounts of 'me' and the contacts coming from the accounts. Do not forget to explain how do we merge the same user in different accounts under one 'identity'. Also the authorization flow.

### Special remarks

Maybe we need to add here something

### Related information

Links to external docs (QT-contacts, Qt-Landmarks would be nice)

Each value is represented by an appropriate subclass with two major exceptions TYPE=home and TYPE=work. They are to be expressed by the roles these contact media are attached to i.e. contact media with TYPE=home parameter are to be attached to the default role (nco:Contact or nco:PersonContact), whereas media with TYPE=work parameter should be attached to nco:Affiliation or nco:OrganizationContact.
