The Proposed Specification is available in several formats (OEBPS, HTML, PDF, MS Word) at:

A note from the Publication Structure Working Group:

OeBPS 1.2 is not, by itself, the ónew OeBPS specificationÇ. Original planning for that specification identified, as reported earlier, four areas for enhancement: content provider control over presentation, support for international content, linking and navigation functionality, and metadata support. The PSWG has worked intensely over the last year and half and has made considerable progress in several of these areas. However, we decided, with the approval of the OeBF Board and the Systems Working Group, that rather than delaying the release of the completed work in presentation control, we should make this work available now, particularly as it could be done with minimal impact on the conformance of existing content. This decision allowed the highest priority area to be addressed now, without waiting until all enhancements were completed.

Consequently OeBPS 1.2 is a tightly constrained update to OeBPS 1.0.1: it provides a great deal of new functionality in the area of presentation control, but it deliberately minimizes all other changes to 1.0.1. This deliberate restriction allows us to (i) make available high priority enhancements sooner rather than later, (ii) maximize compatibility with existing OeBPS content, and (iii) better factor the differences between between 1.2 and and 2.0.

The relationship between OeBPS 1.0.1 and OeBPS 1.2 is more explicitly described in the OeBPS 1.2 proposed specification in section 1.4.4 (óCompatibility of Version 1.2Ç), section 1.7 (óFuture DirectionsÇ), and APPENDIX D (óDifferences Between the Basic OEBPS 1.2 and 1.0.1 Document VocabulariesÇ) and we strongly encourage reviewers to turn immediately to these sections in order to understand the limited scope and intentions of OeBPS 1.2.
