See also the threat "Meaning of property "url"" on public-vocabs mailing list. Martin Hepp's question in http://lists.w3.org/Archives/Public/public-vocabs/2012Oct/0045.html are still not answered:

Regarding the publisher, we also use a blank node solution in the triple store that works like this: 

<http://lobid.org/resource/HT014576567> <http://purl.org/dc/terms/publisher> [
     a <http://xmlns.com/foaf/0.1/Organisation> ;
     <http://xmlns.com/foaf/0.1/name> "Velbr\u00FCck Wiss." ;
     <http://www.w3.org/2003/01/geo/wgs84_pos#location> [
          a <http://www.w3.org/2003/01/geo/wgs84_pos#SpatialThing> ;
          <http://www.geonames.org/ontology#name> "Weilerswist" 
          ]
      ] .

This could easier be translated to schema.org: 

@prefix schema: <http://schema.org/> .

<http://lobid.org/resource/HT014576567> schema:publisher [
     a schema:Organization ;
     schema:name "Velbrück Wiss." ;
     schema:location [
          a schema:Place ;
          schema:name "Weilerswist" 
          ]
      ] .

Description of an item

Describing item using schema.org

As far as I can see, only the two links to the webpages describing the item might be expressed with schema.org using schema:url (although this is still unclear): 

@prefix schema: <http://schema.org/> .

<http://lobid.org/item/HT014576567%3AHWB25011>
    schema:url <http://lobid.org/resource/HT014576567/about> , <https://opac.ub.ruhr-uni-bochum.de/webOPACClient/start.do?Language=De&Query=010%3D%22HT014576567%22> .

Taking into account the "Holdings via Offer" approach, this could look like: 

@prefix schema: <http://schema.org/> .

<http://lobid.org/item/HT014576567%3AHWB25011>
    a schema:Offer ;
    schema:businessFunction <http://purl.org/goodrelations/v1#LeaseOut> ;
    schema:sku "HWB25011" ;
    schema:itemOffered <http://lobid.org/resource/HT014576567> ;
    schema:seller <http://lobid.org/organisation/DE-294> .
