Hi,
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:
http://purl.org/ontology/daia/Item
http://purl.org/spar/fabio/Item
http://purl.org/vocab/frbr/core#Item
In lack of existing RDF properties for library holdings I created
http://purl.org/ontology/daia/label
for call numbers and
http://purl.org/ontology/daia/heldBy
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:
http://www.bic.org.uk/e4librariesfiles/pdfs/110524%20UK%20Data%20Model%20for%20RFID%20in%20Libraries%20final.pdf
http://www.bic.org.uk/e4libraries/11/RFID-/
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):
http://uri.gbv.de/item/opac-de-hil2:epn:134005953
http://uri.gbv.de/item/opac-de-7:epn:943768179
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?).
