Open E-Book
A group that aims to promote electronic books (e-books) by defining a standard for their format.
Under the name Open E-Book Publication Structure, the group of manufacturers known as the Open E-Book Authoring Group published the first standard of this kind in September 1999.
It is designed to allow publishers to release their publications in a format that can be displayed by all e-book readers.
The HTML and XML formatting languages are the technical basis for this specification.
