Aspects of the evolution

aspects already evident

an end user format and a production model
XML centrism; parallell publishing: DTB, Braille, Large-print, E-text, standard book...
access to print source text increasingly critical
USA: the NIMAS requiring publishers of educational materials to produce and make available DAISY 3 XML content
open standards; open development
collaboration with open standards bodies is continuing; open source development continues
format normalization
supports, but is not based on a specialized format (vinyl, four track tape, moon, braille), but rather based on a format living at the center of concurrent mainstream technology: XML.

aspects soon evident

media agnosticism; ability agnosticism
ability, rather than disability, determines interaction modalities
media type inclusion selectable by producer
grammar type adaption by producer
modalities customizable by user (read-time user adaptation)
simplicity remains a key concept
interlending and the global library
from bilateral to global
we need refinement of DTB bibliographical metadata
