One revenue stream for publishers is secondary licensing to content aggregators and syndicators who license content from many sources, then provide it to audiences who pay a premium for access to timely and specialized content. To better serve aggregators and syndicators and their audiences, as well as streamline production of their own Web sites, major publishers are "XML-izing" their production workflows, and both aggregators and publishers are moving to a standard format to maximize efficiencies.

That format is the newly released PRISM Aggregator DTD, a particular use case of PRISM that integrates PRISM metadata with the Modular XHTML DTD for content markup. This talk provides an overview of: the publisher challenges in XML-izing production workflows, the business of secondary licensing, the requirements placed on the PRISM Aggregator DTD, the experience of integrating the PRISM metadata fields with the Modular XHTML specification, and feedback received from top publishing industry executives.
