and other ontologies do not really cover bibliographic resources as managed in
libraries. This ontology is probably the simplest ontology that could work.""" .

# Rules
############################################################
# The exemplar of an edition is also exemplar of the edition's document.
# { ?edition sobr:editionOf ?work ; sobr:exemplar ?copy } => { ?work sobr:exemplar ?copy }
# If a document is both edition and exemplar of the same document, it is it's own exemplar.
# For instance you can view a museum object as object with only one copy (itself).
# { ?work sobr:edition ?both . ?work sobr:exemplar ?both } => { ?both sobr:exemplar ?both }
# The following rules are disputable:
# They can be assumed as always given because they add no information.
# Every edition is it's own edition
# { ?edition a sobr:Edition } => { ?edition sobr:edition ?edition } .
# Every item is it's own exemplar
# { ?copy a sobr:Item } => { ?copy sobr:exemplar ?copy } .

By the way, SOBR does not accept disjointedness of bibo:Document and bibo:Collection.
