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)

6WHAT IS RDA?“RDA provides a set ofguidelines and instructions onformulating data to supportresource discovery.“
7RDA: Purpose and scope RDA provides a comprehensive set ofguidelines and instructions covering all typesof content and media.RDA 0.0 Purpose and Scope
8Scope Consideration has been given to themetadata standards used in othercommunities(archives, museums, publishers, semanticweb, etc.) to attain an effective level ofalignment between those standards andRDA.
