General Rules for Metadata Mapping to RDF[edit]
Item Startnode[edit]
- the subject of the first item triple should be the value of the system (escidoc-id) identifier
- e.g.: escidoc:42365456 dc:title "This is my book"
1:1 Connections[edit]
- elements that can occur atmost 1 times are represented as direct predicates of the startnode.
- e.g.: PND:56235 foaf:lastname "Maier"
1:* Connections with types[edit]
- elements that can occur many times are represented with two triples, the second one for typification
- e.g.: escidoc:5676598 dc:identifier "3234-5656-X". "3234-5656-X" rdf:type "ISBN"
- as far as i know literals cannot be subjects for rdf triples. you'd rather need an intermediate node to attach type info and literal value to.Robert 09:50, 16 January 2009 (UTC)
