Maybe you can try FRBRoo from International Working Group on FRBR and CIDOC CRM Harmonisation. It defines the class F5.Item as physical objects (printed books, scores, CDs, DVDs, CD-ROMS, etc.) that carry a F24 Publication Expression and were produced by an industrial process involving a F3 Manifestation Product Type
It is a subclass of E84.Information Carrier (CIDOC CRM) which can be related to a collection by the property P46 is composed of (forms part of)

Asunto: Linked Library Holdings/Items


I just started to experiment with RDF encoding of information about library holdings. Has anyone done something in this direction yet, so we can adjust our conceptual models and ontologies?

In my terminology, a holding resource is an "item" as the "Item" entity from FRBR. I created an equivalent item class in DAIA ontology and found that the FaBiO ontology defines its own subclass of frbr:item. I am not sure whether we really need this three classes for library holdings:


In lack of existing RDF properties for library holdings I created


for call numbers and


for a "holding" relationship between item and a library institution. (by the way: is "held by proper English or better "hold by"?). Unfortunately the international ISIL agency has not defined an URI prefix for ISIL yet, so I recommend to use the prefix from lobid.org.

The FaBiO has some more properties that could be used to describe library holdings, but I hesitate to reuse purely theoretical ontologies from academics that have not been applied to real world library data.

ISO 28560 and its data model could also be helpful, but I don't have a copy of it (I think the relevant parts are page 6-12 of ISO 28560-2:2011). This is the best information I could find:


Do we have URIs for "ONIX media format" and "MARC media format" yet and how do you relate an item to its format?

Here are some examples of my current, rudimentary encoding of some holding data in RDF (in German):


To get a visual feeling of the underlying RDF graphs, just add "?format=svg" to the URIs

I am still looking for good RDF properties to connect an item to the library record which is about the item's frbr:Manifestation (or frbr:Expression?)..
