The Open eBook Forum has released an updated version of the Open eBook Publication Structure Specification. Entitled `Publication Structure Specification 1.0.1,’ the new standard for authoring reusable content for eBook devices and readers supercedes the 1.0 version of the OEB Specification. The OEB Publication Structure (OEBPS) is an XML-based specification for the content, structure, and presentation of electronic books. Developed and maintained by the Open eBook Forum, a group of over 85 organizations involved in electronic publishing, the standards body and trade association includes Gold Sponsorship from Microsoft Corporation, Adobe Systems and Intertrust Technologies. Version 1.0.1 of OEBPS, which is based on over a year of industry experience with 1.0, does not add additional features to the specification but only removes ambiguities and corrects errors. Version 2.0 of OEBPS, which will introduce new features and substantial enhancements — particularly in the areas of presentation, linking and navigation, internationalization, and metadata — is currently under development. The Publication Structure Working Group encourages all participants and interested parties to download copies of the OEBPS 1.0.1 specification from the Open eBook Forum web site. Multiple formats are available. www.openebook.org
