= DCMI Metadata as linked data =
 
== About the linked data examples ==
 
To present these examples in a concise form we use the [http://www.w3.org/TeamSubmission/2008/SUBM-turtle-20080114/ Turtle syntax for RDF]. The examples therefore appear in code lines such as:
 
  @prefix ex: <http://www.example.com/>.
  ex:aResource ex:aProperty "An RDF Literal" .
 
or
  @prefix ex: <http://www.example.com/>.
  ex:aResource ex:aProperty ex:anotherResource .
  ex:anotherProperty "An RDF Literal"@en .
 
Within the examples we use different namespaces. The following prefixes are used to specify the namespaces we use for our examples:
 
For the '''Dublin Core namespaces''' we use:
 
* @prefix dc: <http://purl.org/dc/elements/1.1/> (DCMI legacy namespace used for the 15 core properties)
* @prefix dcterms: <http://purl.org/dc/terms/> (DCMI terms namespace of the DCMI terms - properties, classes and datatypes)
* @prefix dctype: <http://purl.org/dc/dcmitype/> (DCMI type namespace of the DCMI classes of types)
 
'''Further namespaces''' used are:
 
* @prefix ex: http://www.example.org/ (an exemplary namespace)
* @prefix xsd: http://www.w3.org/2001/XMLSchema# (namespace of the XML Schema language)
* @prefix rdf: http://www.w3.org/1999/02/22-rdf-syntax-ns# (namespace of the rdf vocabulary)
* @prefix rdfs: http://www.w3schools.com/RDF/rdf-schema.xml (namespace of the rdf schema vocabulary)
* @prefix foaf: http://xmlns.com/foaf/0.1/ (namespace of the "Friend of a Friend" vocabulary)
* @prefix gnd: http://d-nb.info/gnd/ (namespace of the authority files of the German National Library)
* @prefix mime: http://purl.org/NET/mediatypes/ (namespace for MIME media types vocabulary)
* @prefix skos: http://www.w3.org/2004/02/skos/core# (namespace of the SKOS vocabulary)
 
== Terms namespace ==
The main difference between the legacy namespace and the terms namespace is the definition of ranges and domains for most terms of the last. The definition of a domain governs the entities for which a property may be used. The definition of a range governs the usage of literal and non-literal values in context with a property.
 
== Examples for properties of the terms namespace using non-literal values ==
 
=== dcterms:abstract ===
 
There is no range defined for dcterms:abstract. Therefore you can use it either with non-literal values and with literal values. For an example with non-literal value see dcterms:description.
 
=== dcterms:contributor ===
 
The range for dcterms:contributor is dcterms:Agent. All values used with this property have to be instances of the class [dcterms:Agent] . '''dcterms:contributor must not be used with literal values'''.
 
You may use dcterms:contributor only with non-literal values.
 
<span id="exCon1"></span>
ex:myMusic dcterms:contributor gnd:135066719 .
gnd:135066719 foaf:familyName "Elliott" ;
              foaf:givenName "Missy" ;
              foaf:nick "Missy E" .
 
=== dcterms:creator ===
 
The range for dcterms:creator is dcterms:Agent. All values used with this property have to be instances of the class [dcterms:Agent] . '''dcterms:creator must not be used with literal values'''. You may use it only with non-literal values.
 
<span id="exCre1"></span>
ex:myBook dcterms:creator _shakespearesName .
_:shakespearesName foaf:familyName "Shakespeare" ;
                    foaf:givenName "William" .
 
=== dcterms:description ===
 
There is no range defined for dcterms:description. Therefore you can use it either with non-literal values and with literal values.
 
<span id="exDes1"></span>
ex:myMusic dcterms:title "Thriller" ;
            dcterms:description <http://en.wikipedia.org/wiki/Thriller_(album)> .
 
=== dcterms:extent ===
 
The range of dcterms:extent is the class dcterms:SizeOrDuration. All values used with dcterms:extent have to be instances of this class. Therefore the property may only be used with non-literal values.

ex:myVideo dcterms:extent [ rdf:value "21 minutes" ] .
 
<span id="exExt2"></span>

=== dcterms:format ===
 
The range of dcterms:format is the class dcterms:MediaTypeOrExtent. All values used with dcterms:format have to be instances of this class. Therefore the property may only be used with non-literal values.
 
<span id="exFor1"></span>
ex:myPicture dcterms:format mime:jpeg .
 
=== dcterms:language ===
 
The range of dcterms:language it the class dcterms:LinguisticSystem. All values used with dcterms:language have to be instances of this class. Therefore the property may only be used with non-literal values.

          and Scott's fixpoint induction. The aim of the book is to present these
          different verification methods in a simple setting and to explain their
