“Practical RDF”, Powers, 2003, is a tutorial on the relational data format (RDF) specified as part of the semantic web for automated machine data exchange. Where XML was a file syntax, RDF provides relationships through the notions of class and property. It is a type of metadata which has been applied for catalogs, directories, informatics, business process ontologies, friend-of-a-friend lists, RSS aggregation, & knowledge bases. The book discusses how RDF can be used to store data, show relationships between universal resource identifiers (URIs), translate between different relational data formats or bases, formalize contents for operations (edit, parse, browse, search, query, reify or make statements about statements), & demo applications written in various languages, APIs, or toolsets. Working group discussions have since been closed. Some of the external sourcecode URLs no longer exist, but most are active. Actual realworld projects are detailed, e.g. Mozilla or CERES/NBII vocabulary. The book closes on the theme of semantics. More RDF content means that machines can transfer data without loss of information. This book may be interesting as a narrative of content on w3c rdf & as a classic that cites many of the early code authors while illustrating the efforts to implement & explore the RDF specifications.
