This document summarizes a webinar on deploying Resource Description and Access (RDA) cataloging and expressing it as linked data. The webinar speaker, Alan Danskin from the British Library, discussed RDA as a cataloging standard that provides guidelines for describing resources to support discovery. He explained how RDA works with linked data by using entities, relationships, and attributes expressed as URIs. Challenges in applying RDA as linked data include the complexity of the FRBR model and publishing RDA vocabularies as linked open data. Application profiles help apply RDA by defining the metadata elements, policies, and guidelines for a specific domain or community.

Scope
Consideration has been given to the
metadata standards used in other
communities
(archives, museums, publishers, semantic
web, etc.) to attain an effective level of
alignment between those standards and
RDA.

I certainly don’t claim any deep expertise in linked data or RDF, so here is a very brief introductionRDF is the official W3C Recommendation for Semantic Web data models.RDF is a deceptively simple way of expressing information by modelling whatever you want to say as statements including a subject and object, linked by a predicate. The “triple”.– we can think of them as sentences in a language – with a subject, a verb, and an object. Using this approach we can say George R.R. Martin is the creator of (the novel) A game of thronesHowever, rather than using literal strings, like George R.R. Martin, to represent things of interest, RDF encourages us to use URIs to identify each component of the triple. Using URIs has many advantages. It allows us to free identification of the thing from any specific label. It allows lots of information about a thing to be associated with the thing. It also makes them identifiable and actionable by machines.In this context the concept of the “record” or “description”, so familiar to librarians, is atomised into separate statements.For example, George R.R. Martin (see slide)
