Adobe Mars technology
- Hi all,
Adobe is coming out with a technology called "Mars". An XML based
representation of generating PDF documents.

certainly make it easier to develop tools that generate and read PDF,
but since such tools already exist in a variety of forms and platforms
that doesn't really change much--anybody who needs to do sophisticated
things with PDF reading or writing today can already do it.
But I don't see that it can hurt.
It at least opens the possibility that you could, for example, generate
a final form deliverable directly with XSLT, rather than using a library
to generate PDF. But again, for most people who need that using the
library isn't that hard as it is and doing the kind of composition that
you get from FO is beyond what you could realistically do with an XSLT
anyway (and why would you want to?).
Maybe it would have some greater value in terms of being able to embed
foreign vocabularies in the data but you can already do that today with
PDF (to a degree anyway) and very few tools even take advantage of
things like tagged PDF.
This seems most like a reaction to Microsoft's XML Paper Specification
(XPS: http://www.microsoft.com/whdc/xps/default.mspx), which in turn
looks like Microsoft trying to do an end-run around Adobe and close the
loop on the full suite of specifications needed for going from documents
as authored to documents as delivered. So this feels like a more or less
pointless standards battle rather than a sincere attempt to provide the
community with a standardized solution to an as-yet-unmet requirement.
For print production I don't see that it matters: printing houses are
all use PDF-based workflows and it's unlikely that that will
change--there's too much investment in tools and techniques.
For online delivery I doubt anyone much cares what the delivery format
is as long as they have a reader. And unless Microsoft simply refused to
produce PDF as output from its tools (which it can't do) there's little
motivation for anyone to produce anything other than PDF.
That is, given the choice between new composition feature X and support
for direct generation of Mars of XPS output instead of PDF, which would
you ask your FO engine vendors for? I know my answer....
