The RDA elements, roles and vocabularies from the RDA elements list have
all been added to the metadata registry:
http://metadataregistry.org/schema/show/id/1.html [elements]
http://metadataregistry.org/schema/show/id/4.html [roles]
http://metadataregistry.org/vocabulary/list.html [vocabularies under
RDA...]
From these pages, if you click on "RDF" at the bottom right you receive
the entire schema or vocabulary in RDA/XML.
We know that there are updates we haven't yet received, and that some of
the vocabulary lists haven't yet been made available, and we will fill
those in when we receive them.
There are some "quirks" that will need to be worked out. In particular,
RDA treats roles such as "illustrator" "author" "composer" as a
vocabulary that is used in relation to personal and corporate names. Our
intention is to use the roles as properties in the description of the
resource with a personal or corporate entity identifier. To bridge these
two different viewpoints, we decided to code RDA roles as a separate
schema. That, however, surfaces some problems where RDA has elements
like "publisher name" that make use of a role as property. I think we'll
need to do some data modeling to figure out the best solution.
It would be interesting at this point to try to develop some simple
application profiles. I encourage experimentation in this area! We can
post these on the wiki. If you are familiar with the Dublin Core
Description Set Profile, it might be interesting to code some
experimental APs using the draft XML schema:
