Notes

Example 3

bf:baseMaterial [

bf:code [ rdf:value “o” ;

bf:source [rdf:value “marc007ng04” ] ] ;

bf:note [ a bf:Note ;

rdfs:label “Image printed on thick gold paper.” ] ] .


There is an untyped resource, which one imagines is a Code, with value "o".
There is an untyped resource, which is some sort of Source, with value "marc007..."

 

 

Item

Example (truncated)

<http://bibframe.example.org/item/itemZ>

bf:shelfMarkLcc [rdf:value “LB2395.C65 1991” ] ;

bf:usageAndAccessPolicy [

a bf:AccessPolicy ;

rdf:value “unrestricted” ] .


There is an LCC, and its value is LB...
There is a Policy and its value is "unrestricted"   
Note -- this use is not very machine friendly. A better model would have identifiable policies, with their own URIs.
