Well, in my quest to get my E-book published, I keep learning new tricks. Today I want to talk about the EPUB validator, http://validator.idpf.org/ This little tool is absolutely necessary if you want to get your book into iBooks or any of the other major vendors. The idea is that it goes through and finds in-depth issues embedded in your book. I thought I had all of the pieces cleaned up, but this tool found a few more.
1. If you use lists, going too deep (like 1, a, i), it seemed to run into issues.
2. Very long screenshots are no longer interpreted like a PNG file. I had several images that were a scolling web page, and it was very long. So I had to break the image into several pieces.
The other trick that I learned is that an EPUB file type is really just like a zip file. I’m sure many of you already knew that, but it was news to me. The EPUB validator is rather cryptic. The errors that it give make no sense until you open up the zipped up EPUB file, then you can see the actual issues. Initially, I was trying to figure out how it gave you line items and weird file names. So be sure to unzip the file if you want to solve the issues.
That’s all for today. Thanks for reading,
