Open Open eBookeBook (OEB) (OEB) SpecificationSpecification
• OEB defines a standard format for exchanging eBooks between Publishers and eBook Reader Systems.
• The Publisher who invests in converting content to OEB will be guaranteed that numerous systems will be able to display that content.
• OEB was NOT designed to be the format displayed on rendering devices, whether hand-held devices or desktop computers.
• It is expected that any OEB eBook Reading System will convert OEB to a proprietary format before final delivery to the end-user.

OEB is not...OEB is not...• OEB is to eBooks as MP3 is to music
…. NOT!!!
• MP3 is delivered to end-user who uses any player to “render” the music file.
• OEB is processed and some proprietary format is delivered to the end-user.

The OEB specification goalsThe OEB specification goals•The specification should bolster consumer and publisher confidence in the performance of eBook Readers and the utility of eBooks
•The specification should limit the burden on content providers of adopting the specification – in particular, by exploiting existing data, tools and expertise and ensuring predictable Reading System performance
•The specification should limit burden on Reading System developers – specifically, by defining a reasonable base-line functionality for OEB compliance
•The specification should have an immediate and direct impact on the creation of a flourishing eBook industry
•The specification must align industry practices to scale with emerging standards (particularly XML)
•The specification must include a standardized mechanism for adding features beyond the base functionality
•The specification must support interoperability between vendor systems
•The specification must encourage innovation and competitive differentiation
• tags: book, title, author, …• start tag: <book>, end tag: </book>• elements: <book>…<book>,<author>…</author>• elements are nested• empty element: <red></red> abbrv. <red/>• an XML document: single root element
well formed XML document: if it has matching tags22 January 2003 22
TerminologyTerminologyThe segment of an XML document between an opening and a corresponding closing tag is called an element.
• Metadata is “structured data about data” • Metadata is language and used to:
– Organize and manage content– Support discovery of resources– Filter and direct content in channels– Enable automated discovery and manipulation
of resources
• As the eBook industry grows, metadata becomes more important
22 January 2003 31
eBookeBook Metadata IssuesMetadata Issues
• Who provides metadata? – author? “publisher”? professional cataloger?
extracted from content?
• Is metadata “integrated” with data?– related question: is metadata a first class object?
• Formats!– which ones?– extensible?– paradox: the more powerful the format, the less
likely it will be used...
22 January 2003 32
Metadata FormatsMetadata Formats
• MARC is very rich– good candidate for an “archival” metadata format,
from which simpler formats can be derived
• Dublin Core designed to be simple enough for the average author to generate by hand– only 15 core fields defined
• Other formats defined for specific purposes:– BibTeX: TeX/LaTeX publishing– RFC-1807: email exchange

Conclusions (1)Conclusions (1)• Although there has not existed a unique
standard for eBooks, some common basic technologies have emerged, e.g., XML, XSL, RDF and DC
• Authors and publishers could employ these technologies to create their eBooksand be assured that the eBooks, through some transformation, would be readable and accessible by any device
22 January 2003 55
Conclusions (2)Conclusions (2)• Other issues:
–Digital Rights Management• “enables digital commerce”• “protection of digital content”• “secure ebook distribution”• “ensures content authenticity”• “participant identification”
– Licensing– Inter-Library Loan–Business Models for Selling eBooks
