Re: [office] How to add animations for shapes on master pages

[Peter Korn <Peter.Korn@Sun.COM>]

Hi Dave,

[moving just to the SC mailing list]

Indeed, your example of the animated graph is a good one.  On the flip 
side, you can imagine something like the animated logo of a company (vs. 
the static image logo of that same company), or images of tweeting birds 
in the background of a presentation on ornithology.  The animation 
itself contains no semantic meaning - it is decorative.  It is, perhaps, 
one step above the interstitial slide animations, where one slide wipes 
left to the other, vs. irising open. vs...

What I think we need to do is ensure the format provides a means to 
convey at least a text description of the animation meaning, and to 
write guidelines that help authors decide when they should use it.  That 
of course means we need author guidelines (vs. authoring tool guidelines).
