Steve, they seem to be spread across the RDA entities. Agent has "is
respondent of" (of a thesis, that is). Work has "has respondent". I
honestly haven't looked at it all closely enough to have an idea of how
it works. So, yeah, all of the above/below.

Karen,
Perhaps I am confused. You are speaking of relators like editor and degree
supervisor but you then talk about RDA Agent Properties. Wouldn't the RDA
equivalent of these relators be in Work Properties or Expression Properties?

Subject: [External] [CODE4LIB] LoC Relators as Properties
C4L'rs - I send the email below to the BIBFRAME list and apologize if you have
already seen it. I am trying to understand if there is interest in having an
RDF vocabulary of agent relationship *properties* (editor, illustrator, funder,
artist). The current entries in the LoC relators list are defined as Things
(SKOS concepts) but not predicates (see exceptions explained below). The RDA
agent vocabulary [3 below] takes a markedly different approach and I would be
interested to know if anyone is using that and if you have found that
sufficient.
Thanks,
kc

Subject: [BIBFRAME] LoC Relators as Properties

All,
I'm writing to solicit your thoughts on using LoC relators [1] as properties.
It's a bit more complex of a question than it sounds, but I'll try my best.
This comes about because of a project at Dublin Core for a Scholarly Resources
Application Profile [2] (SRAP). The developers of SRAP (from the Finnish
National Library) would like to use the following relators as properties in
their profile:
Degree supervisor | http://id.loc.gov/vocabulary/relators/dgs
Editor | http://id.loc.gov/vocabulary/relators/edt
Funder | http://id.loc.gov/vocabulary/relators/fnd
Opponent | http://id.loc.gov/vocabulary/relators/opn
Praeses | http://id.loc.gov/vocabulary/relators/pra
(More may be added later).
As you may know, LoC relators are defined in MADS and in SKOS as concepts. In
the downloaded MADS file you can find the declaration:
rdfs:subPropertyOf <http://purl.org/dc/elements/1.1/contributor>
in about 105 of the nearly 400 relators defined there. This was added in the
early 2000's to relators that were deemed to be in the spirit of dc:contributor.
For example
<http://id.loc.gov/vocabulary/relators/act> a madsrdf:Authority ; madsrdf:authoritativeLabel "Actor" ; madsrdf:code
"act" ; madsrdf:definitionNote "A performer contributing to an expression of a work by acting as a cast member or player in a
musical or dramatic presentation, etc."@en ; madsrdf:editorialNote "changed MARC def"@en ; madsrdf:hasBroaderAuthority
<http://id.loc.gov/vocabulary/relators/prf> ; madsrdf:hasNarrowerAuthority <http://id.loc.gov/vocabulary/relators/vac> ;
madsrdf:isMemberOfMADSCollection <http://id.loc.gov/vocabulary/relators/collection_BIBFRAMEWork>,
<http://id.loc.gov/vocabulary/relators/collection_PastPresentRelatorsEntries>,
<http://id.loc.gov/vocabulary/relators/collection_RDA>,
<http://id.loc.gov/vocabulary/relators/collection_RDAContributor>,
<http://id.loc.gov/vocabulary/relators/collection_RDAWork> ; madsrdf:isMemberOfMADSScheme
<http://id.loc.gov/vocabulary/relators> ; rdfs:subPropertyOf
<http://purl.org/dc/elements/1.1/contributor> .
Because of this subproperty declaration, it follows that these relators can be
used as properties in RDF. Unfortunately, most of the relators that SRAP wishes
to use are not so defined.
Note that RDA defines relators as "agent" properties [3] and the National
Library of Sweden has created its own list based LoC's relators, but in which they are
defined as properties.[4] However, it is generally thought that the LoC list is the best
known, the sine qua non of relator lists, and that is what the developers of SRAP prefer
to use.
All of that is background for this question:
IS THERE A DESIRE IN THE COMMUNITY TO USE LoC RELATORS AS PROPERTIES?
If so, the when and how could be discussed next.
