Re: Support for slide-based media?

Hi Andrew,

I missed this message to this list somehow.  From the DFXP perspective,
there is only the text itself (in the DFXP resource/file); there is no
other content. What that means is that any other content to which DFXP
should be synchronized must be accomplished by external means.
Additionally,
DFXP does not support event based timing that might derive from a user
action; therefore, the only effective way to represent this presentation
in DFXP would be to use distinct DFXP files for each "slide" and then
use something like SMIL (or some other external playlist mechanism) to
trigger activation of each DFXP file.

I realize that this answer is probably not what you are looking for;
however, DFXP was designed to meet a limited set of requirements that
does not cover the use case you describe.

Regards,
Glenn

I'm wondering about support for slide-based and interactive media in
DFXP.  Macromedia Breeze shows one example of this type of media, but
other examples exist whenever an audio narration is delivered along with
a powerpoint presentation and the user needs to (or is allowed the
option of) advancing to the next slide manually.  

SMIL folk will be advocating for use of the excl element, but we're not
using smil to synchronize the overall presentation.  Is there something
in DFXP that I've missed that would help address this issue?

Example breeze presentation -
http://www.macromedia.com/software/breeze/productinfo/overview/presentat
ion/ (this example doesn't pause between slides, but often the pause
/break is built in to allow the user to look at the slide content at
their leisure).

Thanks,
Andrew
