Background ,[object Object],[object Object],[object Object]
Simple DC model ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Qualified DC model ,[object Object],[object Object],[object Object],[object Object],[object Object]
Qualified DC model (2) ,[object Object],[object Object],[object Object],[object Object],[object Object]
But… ,[object Object],[object Object],[object Object],[object Object],[object Object]
Types of structured values ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Definitions ,[object Object],[object Object],[object Object],[object Object]
Name and identifiers as values ,[object Object],[object Object],[object Object]
Linking/embedding requirement ,[object Object],[object Object],[object Object]
Example 1 – dc:creator <?xml version=&quot;1.0&quot;?> <rdf:RDF xmlns:rdf=http://www…. xmlns:rdfs=http://www.w3.org/… xmlns:dc=http://purl.org/dc/… xmlns:my=&quot;http://purl.org…&quot;> <rdf:Description> <dc:creator> <rdf:Description> <rdf:value> Andy Powell </rdf:value> <my:email> [email_address] </my:email> </rdf:Description> </dc:creator> </rdf:Description> </rdf:RDF> Example RDF description using dc:creator…
Example 1 – dc:creator dc:creator Andy Powell… my:affiliation a.powell@uko… my:email … and the RDF model it represents. UKOLN, Univ… a.powell@uko… Andy Po… rdfs:label my:name <?xml version=&quot;1.0&quot;?> <rdf:RDF xmlns:rdf=http://www…. xmlns:rdfs=http://www.w3.org/… xmlns:dc=http://purl.org/dc/… xmlns:my=&quot;http://purl.org…&quot;> <rdf:Description> <dc:creator> <rdf:Description> <rdf:value> Andy Powell </rdf:value> <my:email> [email_address] </my:email> </rdf:Description> </dc:creator> </rdf:Description> </rdf:RDF>
Example 1 – dc:creator dc:creator Andy Powell… my:affiliation a.powell@uko… my:email UKOLN, Univ… a.powell@uko… Andy Po… rdfs:label my:name But… we don’t want to embed all this information into every instance metadata record do we? relatedMetadata <?xml version=&quot;1.0&quot;?> <rdf:RDF xmlns:rdf=http://www…. xmlns:rdfs=http://www.w3.org/… xmlns:dc=http://purl.org/dc/… xmlns:my=&quot;http://purl.org…&quot;> <rdf:Description> <dc:creator> <rdf:Description> <rdf:value> Andy Powell </rdf:value> <my:email> [email_address] </my:email> </rdf:Description> </dc:creator> </rdf:Description> </rdf:RDF>
Example 1 – dc:creator dc:creator Andy Powell… rdfs:label my:affiliation a.powell@uko… my:email UKOLN, Univ… a.powell@uko… Andy Po… my:name Need to separate part of the information out and store it in a single place – in this case in a directory service… <?xml version=&quot;1.0&quot;?> <rdf:RDF xmlns:rdf=http://www…. xmlns:rdfs=http://www.w3.org/… xmlns:dc=http://purl.org/dc/… xmlns:my=&quot;http://purl.org…&quot;> <rdf:Description> <dc:creator> <rdf:Description> <rdf:value> Andy Powell </rdf:value> </rdf:Description> </dc:creator> </rdf:Description> </rdf:RDF> <?xml version=&quot;1.0&quot;?> <rdf:RDF xmlns:rdf=http://www…. xmlns:rdfs=http://www.w3.org/… xmlns:dc=http://purl.org/dc/… xmlns:my=&quot;http://purl.org…&quot;> <rdf:Description> <my:name> Andy Powell </my:name> <my:email> [email_address] </my:email> </rdf:Description> </rdf:RDF>
Example 1 – dc:creator valueURI dc:creator Andy Powell… rdfs:label valueURI my:affiliation a.powell@uko… my:email UKOLN, Univ… a.powell@uko… Andy Po… my:name To do this we need to assign a URI (the ‘valueURI’) to the anonymous ‘value’ node… <?xml version=&quot;1.0&quot;?> <rdf:RDF xmlns:rdf=http://www…. xmlns:rdfs=http://www.w3.org/… xmlns:dc=http://purl.org/dc/… xmlns:my=&quot;http://purl.org…&quot;> <rdf:Description> <dc:creator> <rdf:Description> <rdf:value> Andy Powell </rdf:value> </rdf:Description> </dc:creator> </rdf:Description> </rdf:RDF> <?xml version=&quot;1.0&quot;?> <rdf:RDF xmlns:rdf=http://www…. xmlns:rdfs=http://www.w3.org/… xmlns:dc=http://purl.org/dc/… xmlns:my=&quot;http://purl.org…&quot;> <rdf:Description> <my:name> Andy Powell </my:name> <my:email> [email_address] </my:email> </rdf:Description> </rdf:RDF>
