Hi Karen,
The National Library of Spain's datos.bne.es <http://datos.bne.es>
dataset is making extensive use of the IFLA FRer vocabulary, and some
use of FRAD. I thought it might be of interest to you. Additionally, you
can visually explore an example of the kind of FRBRzation we are doing,
via Miguel de Cervantes the (still) very raw graph example [1], there
you can see more than 3000 resources (nodes) corresponding to WEM
entities, and more than 3500 relationships (edges). As you can see we
only cover a small fraction of the relationships (is creator of, is
embodied in, is realized through etc.). All URIs are dereferenceable but
I am afraid you have to copy and paste them until we make them clickable
in the example. However it is interesting to see the different clusters
corresponding to the most edited and versioned works from Cervantes.
Please let me know if you need more details,
Cheers,
Daniel

I should mention that I am keeping a wiki page [1] relating to the
various versions of FRBR in RDF, with links to discussions around
the issues of modeling -- in particular the question of defining the
FRBR classes as disjoint.
Also, FRAD [2] resembles FRBR in structure, but FRSAD [3] takes a
very different approach with only two classes, Thema and Nomen. An
interesting aspect of FRAD, which reflects standard library
practice, is that it retains the concept of a "controlled access
point" and includes a relationship to the rules under which the
access point was developed and the agency that created the access
point by applying the rules.
If I run into discussions of these latter FRs I will add them to the
wiki page.

*Functional Requirements namespaces published*
Namespaces for the Functional Requirements (FR) family of
bibliographic metadata models have been published in Resource
Description Framework (RDF), the basis of the Semantic Web.
The models
include Functional Requirements for Bibliographic Records
(FRBR),
Functional Requirements for Authority Data (FRAD), and
Functional
Requirements for Subject Authority Data (FRSAD). The
namespaces can be
<http://iflastandards.info/ns/fr/_>.
The FR element set vocabularies include RDF classes and
properties
corresponding to FR entities, attributes, and relationships.
Each
class and property has a Uniform Resource Identifier (URI)
for use in
Semantic Web data triples.
A full de-referencing service is available for each URI.
When used in
an ordinary Web browser, the URI displays HTML pages with
human-readable information about the element or concept.
When used in
a semantic browser, the URI retrieves machine-readable
information in
RDF/XML format. It is also possible to retrieve this format
using an
ordinary Web browser.
For example, the URI for the FRBR entity-relationship
(FRBRer) model’s
Group 1 entity “Work” is
_http://iflastandards.info/ns/__fr/frbr/frbrer/C1001_
<http://iflastandards.info/ns/fr/frbr/frbrer/C1001_>. To
retrieve the
RDF/XML information in a normal Web browser, use
_http://iflastandards.info/ns/__fr/frbr/frbrer/C1001.rdf_
_http://iflastandards.info/ns/__fr/frsad/P2003_
_http://iflastandards.info/ns/__fr/frsad/P2003.rdf_
<http://iflastandards.info/ns/fr/frsad/P2003.rdf_>.
The element set for a specific FR model can be accessed as
follows:
*
FRBRer: _http://iflastandards.info/ns/__fr/frbr/frbrer/_
<http://iflastandards.info/ns/fr/frbr/frbrer/_>
*
FRAD: _http://iflastandards.info/ns/__fr/frad/_
<http://iflastandards.info/ns/fr/frad/_>
*
FRSAD: _http://iflastandards.info/ns/__fr/frsad/_
Registry (_http://metadataregistry.org/___
<http://metadataregistry.org/_>).
These element sets reflect the current published models,
however, as
the FR family is in the process of being consolidated, this
may result
in the eventual deprecation of some URIs.
