Red face Epub validation question

Hello I hope I'm posting this in the right place.


I'm working on turning a family member's manuscript into a epub. I've never made an epub before (web sites with basic XHTML yes, epubs no.) This whole process has been a bit of adventure for me. And headache.

I've already turned the files into an epub and went through the validation at Threepress Consulting Inc's web site once. Errors came up and I went in and fixed those. Rezipped the files and when I sent it through the validation at Threepress only one error came up.

It's now saying the META-INF file is not there. This error didn't come up the first time around.

It's there. I'm not sure what's going on or what I'm doing wrong. Can anyone help?

Thank You.

It has to be ziped correctly. i.e in a certain order.

Well, after going thrugh a helish time with this epub thing I found the best way is working with the smashwords style guide. http://www.smashwords.com/books/view/52 (it's free)

this is a STEP BY STEP GUIDE instructing how to prepare your WORD file to epub. after doing that i finally received from the epub validation website the words i was longing to: PASSED and VALID.....
I can assure you that once you follow this guide it will work. (except for some exceptions like a problematic url link.. or so.:-;

anyway if you need any further assistance - i will gladly do so.
good luck,
Sara

I know that. I am/have done a lot of research into epub before and during this whole process.

I used the method from Elizabeth Castro's book "Epub Straight to the Point" to zip it. The first time around the errors I got were in the XHTML and the TOC part. I fixed those and re-zipped it and then the only error message I got was this: ERROR: MaryQueenOfScots.epub: Required META-INF/container.xml resource is missing

It didn't come up the first time around, but the second. I used the link you provided and zipped it that way and still got that same message.

I'm not sure what is going on, the META INF folder and the container.xml is there. I've checked it and double checked it. I'm sure it's something simple, I just would love to know what it is.

Thanks for the links by and by.

That didn't really help me. Sorry. I did the entire XHTML markup myself in Dreamweaver along with the toc.ncx and content.opf files. The formatting is done (and surprisingly in some ways easier then doing the markup for a web site) I'm just having a problem with that pesky error message at epub validator.

Thank you for trying.

Well ok. I was unaware you did all this research.

Container.xhtml is in your content.opf manifest?
Can you post your content.opf file here?

The container.xml is in the META-INF folder.

I'm attaching the epub that isn't validating.

Any help would be greatly appreciated. I would love to know what I'm doing wrong.

The META-INF directory with your container.xml file contains a tailing space. Meaning that the file entry that should look like 'META-INF/container.xml' looks like 'META-INF /container.xml'.

Remove the tailing space and try again .

Update: Ugh... just repacked your epub. It can now be opened in ADE, but it contains a truckload of errors - among them invalid attributes (you misspelled src as scr which leads to a broken toc). But they are easily fixed (epubcheck is your friend), so it seems that you're pretty close to the end of your journey .

A really very interesting case.
A tiny space makes an epub crashed.

But how could that happen, I tried input a space after a folder name
on my PC, but it's trimmed by Windows automatically.

What Adjust said.

Plus: epub (well, OCF to be precise) specifies for two files to be be present with specific names: mimetype and META-INF/container.xml. The first one declares the zip to be of type epub, the second one serves as starting point telling the program the location and type of the content of the book.
With the space in the directory the file did not have the required name anymore - therefore to the epub engine the the second file (and thus the information on how to find the book content) was missing.

You're right in that windows will automatically erase tailing spaces from created directories (which isn't true for neither Linux nor OSX - didn't know that last tidbit myself until I unpacked the ebook in question).
Unfortunately the zipping process is not simply copying files from A to B. You can declare the specific content entry in the zip header (think file system in a single file) while creating your ebook - and my guess is that something went wrong in that step.
