In March, Mark Matienzo gave this presentation on re-purposing metadata. What really caught my attention was how Mark used the idea of linked data to explain how metadata can be used and re-used. This message is especially poignant given RDA’s focus on relationships. It has also been discussed in several blogs, quite recently by Karen Coyle, in addition to listservs such as NGC4Lib. Moreover, despite a focus on archives, this presentation is a great and simple introduction to linked data and practical applications.
