Creating ePub file in Unstructured FrameMaker 10-RoboHelp 9.

Hello,

I've created a book in FrameMaker, linked it to a project in RoboHelp and generated an ePub file. I can view the file in Adobe Digital Editions, but cannot load it to an iPad and view.

There are some formatting issues that I need to work on (bullets spacing), but the results appear to be fine.

I ran the file though a epub validator online and see that I have several errors:

-length of the first filename in archive must be 8, but was 9.

-character content of element dc:identifier invalid, must be a string with length at least 1

-element spine incomplete

-element navMap incomplete

Can you suggest a way for me to generate ePub files that can be viewed using an iPad (and possibly other devices)?

I've read posts online and viewed videos, but to date, nothing has helped me work through these issues.

Any guidance would be appreciated.

m.e.
