I am developing an Ebook reader for iPhone that loads ePUB file. I would like to know how would I unzip ePUB file format. Is there any examples around?
Thanks.

Unzipping is easier than zipping. Just change extension to .zip and use regular zip tool.
Or on Mac, in Terminal, use
unzip file.epub

I need to get metadata info from a eBook such as author, publication date, publisher, plot, etc. The formats are '.mobi', '.azw', '.azw2', '.azw3', '.epub'.
Is there any cocoa class for that? If not, which libraries do you suggest me?
I think no, but all those formats have xml based metadata formats, so use any xml parser you like.
Just unzip file and see what inside. For example internals of some .epub

It looks like there is a wealth of SVG parsers out there. Has anyone written a SVG generator for Objective-c? I have point data (ideally bezier data) that I want to write out to SVG. If you know of an example or library to do this please let me know.
You can write CGPathRef data (bezierPath.CGPath) to SVG file using MROGeometry library

I am currently trying to parse the semantic structure of a PDF file. I believe the metadata added to make PDFs accessible is the correct way to go about it, but I can't find a library that will handle it cleanly.
I've tried PDFLib TET on iOS but I can't get it to open certain test documents and the error it returns is too obscure to be Googleable.
Are there any other libraries that do the same?
I'd have a look at the pCOS-Library (also from http://pdflib.com). For use in PHP there would be an alternative you could have a look at http://www.setasign.com/. They might have a tool for that purpose.

I'm taking recommendations for either a library in Python or Ruby or a free web service that will simply take a PDF and a pair of image dimensions and spit out an image for each page (jpg or png). Nothing complicated! But it must have point-for-point accuracy to the original PDF. That is all.
ImageMagick uses Ghostscript for PDF files. So skip ImageMagick and use Ghostscript directly. IMHO.
You can use GIMP. Its a very good interface.
Import the pdf file to GIMP
Save the file as .xcf
Operate on the image - edit if required
Export in whatever format you want: .bmp, .jpeg, .png etc.
Try this :) (ImageMagick).

What tool do I need to generate XML intellisense help file as shown below?
You need to add XML Documentation comments to your code, and then in your Visual Studio project build options ("Build" tab) tick the "XML documentation file" checkbox to extract those comments to the XML file.
Try AtomineerUtils or GhostDoc to help you to create/update the xml documentation comments quickly and easily.
