I am at the Online Information show today and tomorrow. Olympia with IMS tech aspects at the back. There is an XML zone claiming to offer support for an integrated publishing workflow. But nothing on JDF. Trust me I am a blogger. No names but I have checked a couple of likely stands. "There is no customer demand." "Never been asked for that."
I think this is a great danger for the printing industry. There are a large number of content providers here. They will get the idea that XML relates to digital workflow but print has gone from the scene.
FT for example. No plans to discontinue print at this time.
