How about using Keynote via iCloud and displaying it in the webviewer ?
You can simultaneously edit the same document with other users.
We have done that, but Keynote for iCloud are to clumsy to work with. And we also need to let .... oh God .. Windows users work with the FileMaker database.
You don't have to be Mac/iOS user.
You can play with my presentation just via this link even without iCloud account:
Thanks for you input it is appreciated.
But I really want a FileMaker centric solution if it is available, if not we will probably go for PowerPoint and Office 365.
Hope that somebody know of a way or if the old tools are still active.
The file formats of both PowerPoint and Keynote have gotten a lot more complex since the last time I looked at something like this; making the XML route a lot more difficult.
What about HTML? You could probably export from FileMaker into a simple file format (text, tab, csv, xml) that an HTML file could read. Find a slideshow library that reads the FM export and do it in a browser.
I've done a few things with RapidWeaver and FileMaker where I took apart a RapidWeaver file and dumped it into a web viewer. Worked fairly well.
I don't know if that could help, but few years ago I have created as an experimentation, a solution to build presentation 100% FileMaker...
It's a set of cards you arrange per project the way you want,
there are various kind of cards (templates) : title, text, portfolio, slideshow, picture, map, installer (container)...
at the end I can deliver a solution that can run on mac or ios, and I could export in pdf...
