I have several catalogs built in InDesign. We export those catalogs as pdfs and have them on our website. They get updated a lot. I would like to have a slightly interactive version of each catalog available for mobile devices. I would love for someone to be able to download a catalog and get some type of notification when the catalog has been updated. Would I need to go through DPS and develop apps for this ability? I would think a fixed layout epub would be sufficient for my design and interactive needs, but will it allow the auto update notifications? I'm sorry if this is obvious, but I have searched and not found a clear answer.
It's a complex issue and there are no absolute answers.
I'd suggest a great book from Sandee Cohen and Diane Burns which gives a good and current overview of the options:
I'll take a look at it. I'd like to know more about all of my choices, so this might be a good start. Adobe offers so many apps and tools now, it's kind of overwhelming.
