I picked up this issue of Library Technology Reports because I was looking for an introduction to Linked Data and RDF (Resource Description Framework), explained in such a way that a traditional MARC cataloger like myself could understand. And that's exactly what I got. In 4 chapters Karen Coyle covers how library data operates today, where elements of MARC have no meaning if taken out of the context of the MARC record. For example, "New York: Penguin, 2010." means nothing without the rest of the record to provide context. She then describes the metadata models of the world wide web, namely RDF, and how the RDF model can be applied to library data so that our bibliographic descriptions have meaning outside the context of the bibliographic record, enabling interaction with outside data. The third and fourth chapters discuss the FRBR model and what the new cataloging standard RDA looks like within the RDF model. The many graphs and diagrams clearly illustrate these abstract concepts, and several examples of XML records demonstrate how these concepts look in actual practice. There's also a great resource list at the end for further reading on FRBR, RDA, RDF, Linked Data, and OCLC Research. This is a great introduction for anyone interested in understanding RDF and Linked Data, and it's very exciting to see what possibilities could be opened up by the adoption of RDA in RDF. ( )
