Basic XML and RDF techniques for knowledge management

This article presents a practical exploration of knowledge management with XML by illustrating techniques for populating Resource Description Framework (RDF) models with data from existing XML formats. As shown in the three code listings, RDF can be used as a companion to customized XML, not just as a canonical representation for certain types of data. This column, with code samples included, demonstrates how easy it can be to jump-start knowledge management with RDF even relatively late in the development game.
