#1383 — Mathematica 8.01 and the CDF plug-in

Has any one succeeded in producing working examples of files in the new 
Computable Document Format? By "working examples" I mean ones that can 
be opened and whose dynamic content can be used by someone who does not 
posses Mathematica but only a CDF browser plugin.

I have tried saving notebooks in the CDF format but when I try to open 
them with the "Wolfram" plugin, I see that it's always "loading" but 
never gets anywhere. When I open such a file with Mathematica, 
everything works fine.

Have I misunderstood how this new format is supposed to work?

Hi,

I had no problem with the tests I've done.

I was also able to get into an unique mht file the cdf, a java script
that checks if the player is installed, and an image that appears if
it is not installed, and explains how to proceed (links to wolfram's
download).

To get a little closer to unreadable source code, each of these files
(cdf, js, png) were transformed into base64 (using Mathematica
itself), and only after, manually registered inside the mht file (lost
some time trying to figure out how this works; if someone knows of a
tool to edit this kind of files, and that manages the base64 option ,
I would greatly appreciate to know about it).

I then sent the mht file to a couple of people that didn't had
Mathematica or any player installed, and everything went as expected.

I also thought of a way of placing inside the mht file, the cdf player
itself, but I think that would violate the distribution license.

I ended up very happy with the toy I made, but it is completely
useless since it doesn't have strong encryption, neither a way of
controlling access to it (signed computer id license, usb dongle,
etc).

And I can also say (or probably insist) that my colleagues, although
they liked the sliders, and locators, they also saw it as a toy, and
nothing more, since they could not get data into it, or save data from
it, or better, interact with it from a different environment (the way
I see it, there is absolutely no integration on this technology, and
integration is or has been the way of the future...).

I can send you an example when I get back to the office (can't send
you my first trial because it has proprietary knowledge, and as you
know, there's no strong encryption...).

Regards,
P. Fonseca

I contacted support about the CDF player, it would seem that at present 
the new player is really just another version of Mathematica Player - 
i.e. there is no PlayerPro support inside it yet!

Hi Andrzej,

I have been able to save simple Manipulate[ ] based notebooks as 8.0.1
*.CDF.
Have tried them with the plugin running either Chrome or Firefox both
latest versions, both running.

Are you able to run the Wolfram demonstartions with the plugin ?
Are you able to run the CDF with the stand alone (not browswer hosted)
CDF player ?
Are you shure that you have the plugin installed ?

Cheers Robert

Yes, it has some limitations but for simple cases seems to work
straightforward: if I put this into a Mathematica notebook:

Manipulate[Plot[x^n, {x, 0, 1}], {n, 1, 10}]

evaluate it and then "Save As" -> CDF I can open the resulting file with
the CDF-Player. After opening it the player shows a warning about unsave
content and I have to click a button "Enable Dynamics" and after that I
can play with the Manipulate. What did you try and what did not work?

Maybe you should try first to open the files within the standalone
CDF-Player (not within the plugin). The plugin seems to have some
further restrictions compared to the standalone CDF-Player, e.g. a
simple MessageDialog did not work in the plugin for me. For simple cases
that probably shouldn't make a difference though. Also if you have
Mathematica and the Player installed I think the plugin will by default
use Mathematica, not the Player, so in that case you are testing the
plugin+Mathematica, not the plugin+Player.

Hard to say if 1) we don't know what your understanding of it is, and 2)
the format is not officialy released (http://www.wolfram.com/cdf/) :-)

hth,

albert
