+This document defines a set of terms for describing people. It defines how to describe people's characteristics such as names or addresses and how to relate people to other things, for example to organizations or projects. For each term, guidance on the usage within a running example is provided. This document also defines mappings to widely used vocabularies to enable interoperability.

+<h2>Scope</h2>
+<p>
+This document is aimed at both publishers and consumers of Linked Data. We assume that the reader has a certain familiarity with RDF and RDF Schema as well as well-known vocabularies, such as FOAF or Dublin Core. The goal of the document is to specify an interoperable way to describe people and their relationships to other entities such as organisations or projects.

+ Recently, ColCids won a contract for providing an Open Data platform, awarded by the Santa Clara County. The

+ point in the County of Santa Clara is Björk Guðmundsdóttir. To ensure a successful project delivery, Jane has
+ invited 東海林賢蔵, a business contact and Open Data guru she recently met at a local event, to brief her and 
+ the CoolCids team on the challenges and requirements in the domain.

+<p>If only the person's name is known <code><a href="http://xmlns.com/foaf/spec/#term_name" title="FOAF Vocabulary Specification">foaf:name</a></code> MUST be used.</p>

+	<p class="practicedesc">One sometimes finds specialisations of a person in a domain, for example, in the legal domain there is a distinction made between a natural person and a legal person. In such a case the publisher should, in addition to the domain-specific type (e.g., <code>legal:NaturalPerson</code>) explicitly set the type <code>foaf:Person</code> in order to increase interoperability. This also allow systems that do not perform reasoning, for example, plain SPARQL processors to benefit from it. <a href="http://answers.semanticweb.com/questions/13715/owl-subclassing-vs-new-properties-for-existing-classes" title="OWL subclassing vs new properties for existing classes - ANSWERS">Read more ...</a></p>

+<h2 id="i18y">Interoperability considerations</h2>
+<p>Our concept of a person is based on <code>foaf:Person</code>, but there are many more conceptualisations in use, for example as defined by the <em>Interoperability Solutions for European Public Administrations</em> (<a href="http://ec.europa.eu/isa/">ISA</a>) project, the <a href="http://schema.org/" title="Home - schema.org">Schema.org</a> project by the search engine providers Bing, Google, Yahoo! or as found in the Personal Information Model (PIMO) by the <a href="http://www.semanticdesktop.org/" title="Semantic Desktop">Semantic Desktop</a> project.</p>
+<p>To enable interoperability and, in general, to make the data more useful, we define mappings of terms, in the following. An implementer of this spec SHOULD support these mappings.</p>
