I found some magazines with this extension _drp.epub
I know how to build an epub (.epub) How can I make an (_drp.epub)
Is there a tool for it?

The _drp is simply part of the file name... not part of the extension. I'm guessing it's a run-of-the-mill epub. ;)

It looks that it's has some influence in the file because when I delete that part of the name, the file stops working properly.

That makes no sense. What are you trying to read the file with that it "stops working" when you change the file name? It should be just a zip file. Change the .epub to .zip, open it up and see what's going on in there.

Exactly as you read, the original file name is COSMO-20101001_drp.epub. I change it to COS_TEST.epub and it stop working properly, now it shows only the basic pages, without the posibility to rotate pages when you move the tablet or zoom in/out the images.

Stops working properly in what reading application?

Maybe this (http://code.google.com/p/epub-revision/wiki/BNFixedFormat) has something to do with it?

The Barnes & Noble Fixed-layout Format
...
DRP is essentially an ePub: it’s a zip file with the normal ePub structure, including an OPF with a manifest, spine, etc. In essence, a DRP contains two categories of items: images of pages rasterized from the incoming PDF, and the text (and images, if desired) of “articles” contained in the magazine (XHTML). There are a couple of ways in which a DRP deviates from the ePub standard: 1) the format & reading system allow images to be top-level items in the spine, and 2) the addition of a replica map (described in detail later), mapping page images to XHTML content (and vice versa). “ArticleView™” presents the text of an article plus a headline, byline and one or more images in an HTML view. In our implementation, the article view “floats” above the page image, with some of the underlying page image visible along the sides of the article view.
...

But depending on part of the filename to clue in the reader software as to what format it is dealing with seems kludgy at best - and 1970's kludgy at that. :eek:

No doubt! That's just silly. :eek:

Thank you DiapDealer that is exactly what it is!!
When you open the file it gives you the option to see the images/PDF over the regular format and choose if you prefer to read it that way or a regular epub text; it actually gives you a great chance to appreciate de real layout of the magazine or not.
Do you have any idea how to accomplish this? Any software? ...ideas? I'll check with Barnes and Noble

st_albert's the one who figured it out, but no, I don't know of any software to build these special fixed-layout epubs.

It sounds a lot like Amazon's Print Replica books.... PDF's in a wrapper.

Thanks st_albert's. If you are interested to find out how it works, here is the link to download the file http://code.google.com/p/epub-revision/downloads/detail?name=COSMO-20101001_drp.epub&can=2&q=

There is no publicly available software to make the DRP files, however we are working on a InDesign plugin that we will make available.

Note however that this is an evolving spec.
