Apparently Mars is not a quick Adobe response to the Microsoft XML offers.
Andrew Shebanow reports in his
blog that a more XML based version of PDF has been in the works for a long time. Somehow it just did not get finished in time for the release of Acrobat 8.
In my opinion this XML stuff should be a priority. Maybe I am stuck on flat static documents but video conferencing seems to me to be a different issue to PDF.
Anyway, the
Mars downloads are available and should be no more trouble to add to Acrobat 8 than some extra features to Vista. More later on how this works.
This discussion is still part of print and drupa. Global Graphics have made a major contribution to the XML print aspects of Vista. My guess is that the approach will work ok, even though I don't think there will be a rush to upgrade in general.
Getting JDF to be accepted could be easier once it is realised that JDF is just another case of XML. Once the XML people get interested in print things could work out quite quickly.
