RDF: Resource Description Failures and Linked Data Letdowns

Introduction

The topic of the Semantic Web, more recently rebranded as Linked (Open) Data, has been in discussed in digital humanities and related disciplines since its inception. Now, more than a decade later, the technology has had more than enough time to run through the hype curve towards the Plateau of Productivity. But where are we really in that timeline? Some sectors have embraced it, and others are catching up quickly, but significant obstacles to adoption remain.

This presentation looks at the major difference between Linked Data and more traditional document-centric technologies, contrasting the benefits with the difficulties in an effort to provide an explanation as to when it is valuable and when the overheads are currently too high. It is intended as an overview to enable the audience to decide for themselves when Linked Data is appropriate for their use case, and what challenges they may run into along the way. Readers may either watch the slides with the recorded presentation or view the slides independent of that recording.

For those unfamiliar with Linked Data, a selection of introductory material is referenced below.[1] A full understanding of the technology is not necessary to engage with the presentation, but knowing the general background would be advantageous to get the most benefit. URIs for the topics referenced in the presentation are also provided after the pdf if they are not on the slides.
