content: A 10th Birthday Salute to RDF's Role in Powering Data Interoperability There has been much welcomed visibility for the semantic Web and linked data of late. Many wonder why it has not happened earlier; and some observe progress has still been too slow. But what is often overlooked is the foundational role of RDF -- the Resource Description Framework. From my own perspective focused on the issues of data interoperability and data federation, RDF is the single most important factor in today's advances. Sure, there have been other models and other formulations, but I think we now see the Goldilocks "just right" combination of expressiveness and simplicity to power the foreseeable future of data interoperability. So, on this 10th anniversary of the birth of RDF [1], I'd like to re-visit and update some much dated discussions regarding the advantages of RDF, and more directly address some of the mis-perceptions and myths that have grown up around this most useful framework. By request, this article is now available as a PDF download. A Simple Intro to RDF RDF is a data model that is expressed as simple subject-predicate-object "triples". That sounds fancy, but just substitute verb for predicate and noun for subject and object. In other words: Dick sees Jane; or, the ball is round. It may sound like a kindergarten reader, but it is how data can be easily represented and built up into more complex structures and stories. A triple is also known as a "statement" and is the basic "fact" or asserted unit of knowledge in RDF. Multiple statements get combined together by matching the subjects or objects as "nodes" to one another (the predicates act as connectors or "edges"). As these node-edge-node triple statements get aggregated, a network structure emerges, known as the RDF graph. The referenced "resources" in RDF triples have unique identifiers, IRIs, that are Web-compatible and Web-scalable. These identifiers can point to precise definitions of predicates or refer to specif…
