It's a fairly well known fact that InDesign 4 and 5 don't place the correct date metadata in the EPUB file. You can fix it manually, or with Sigil (a free download).
The bug is fixed in InDesign CS5.5.
You might want to read some of the better books and videos on creating EPUBs from InDesign. Like Elizabeth Castro's EPUB: Straight to the Point, or Anne-Marie Concepcion's Lynda.com videos on creating EPUB.
Where is the report bug feature anymore? The adobe site keeps giving me 'site not found' results.
http://adobe.com/go/wish is probably what you are thinking of.
But you are almost always better off contacting support for any bug that matters, at http://adobe.com/go/supportportal, because then you can get a bug number and it is more likely to be fixed.
Dear Steve, if you read the details of my question you would realize I am manually fixing the date metadata. I actually came across this problem while following Castro's book EPUB Straight to the Point. The problem was that the content.opf CS5 generates concerning the xmlns is wrong in another way. RIGHT NOW it starts <package xmlns="http://www.idpf.org/2007/opf".... which is MISSING the very important :opf part. It SHOULD be <package xmlns:opf="http://www.idpf.org/2007/opf" ...
Without the xmlns:opf="http://www.idpf.org/2007/opf" if you add any opf data like <dc:date opf-event="original publication"> then the XML invalidates. Why? Because the xml doesnt know where to look of that opf:event.
Hope you understand what I mean now.
Thanks John. This is crazy but Firefox (v4.0.1) gives me a broken link page for both those sites but Safari (v5.0.5) displays them fine. I'll use Safari and try to get the bug report in. Thanks.
Sometimes Adobe's web site(s) gets confused with respect to cookies, and then provides spurious 404 error messages. In Firefox, rightclick View Page Info > Security > [ Privacy & History] : View Cookies, with adobe.com in the search box, click the first line, scroll down to the last line and shift-click it. All should be highlighted. Then Remove Cookies. It will also log you out of the forum though.
