O'Reilly Labs: RDF For All of Our Books, Plus Bookworm Ebook Reader

by | @andrewsavikas | +Andrew Savikas | February 10, 2009

There’s more details on the Labs blog, but timed with our Tools of Change for Publishing Conference, we’ve opened up RDF metadata for all of our books, and have also brought the open source Bookworm ebook reader into O’Reilly Labs. It’s a great way to read any of our ebooks (more than 400 are now available as ebook bundles from oreilly.com) online and from a mobile phone:

The experimental “O’Reilly Product Metadata Interface” (OPMI) exposes RDF for all of O’Reilly’s titles, organized by ISBN. Here’s a snippet of the RDF metadata for iPhone: The Missing Manual, 2e from the OPMI at http://opmi.labs.oreilly.com/product/9780596521677:
