Apache and ODF

Hi,

Today my wife got her new Kindle which comes with a document viewer
based on Apache Freetype for the rendering job and Apache POI which is a
Java library to parse Microsoft documents.
It handles doc(x)/xls(x)/ppt(x) but no ODF. Although I am not deeply
involved in this project, I feel somewhat embarrassed and alarmed
because in the year 2012 the Apache foundation develops excellent tools
to process proprietary file formats but fails to offer anything
equivalent for the free and much simpler ODF standard.
Is my assumption correct that http://incubator.apache.org/odftoolkit/
would be the remedy to solve that problem but due to a lack of
development resources it is not ready for the job?

Greetings,
Andreas Säger

For the records: Amazon does not even deliver .epub files sent via Email
to the mail account of the Kindle Fire HD (it drops attachments into the
home folder). The sender (me) gets an error mail with a list of accepted
formats.

Calligra Author and Calligra Words 2.6 that will be released as beta in next 
week has both a new Epub2 and a MOBI export. This is done because of the new 
Calligra Author application that is aimed especially at creating ebooks.

Upcoming versions will also have Epub3 support with dynamic contents.

Generally both modes are supported.  And sometimes it varies based on
the format.

For example, PDF files are fixed-layout.  So they require you to "zoom
and pan" on smaller screens.  But larger screens, like Kindle DX or
iPad can show a full PDF page.

ePub and MOBI digital book files are designed to reflow according to
screen size and user's font size preferences.

But some content types, like magazines on the Kindle, can work both
ways.  The user can choose to have a full-page layout that mimics the
original printed magazine.  Or they can choose to have it reflow per
the screen and font size.

So ideally we would want to support both.

To Ian:

Yes, I agree with you that there shall be options for:
1. Fitful formatting way, for the READING; and
2. Uniform formatting way, for the REPRESENTATION;

Thus, the solution will lead:
A: The bad thing is that there shall be a series of formatting
specification definitions, for Kindle, Kindle Fire, Kindle Fire II, iPad,
iPad Mini, IPod touch, IPhone BLA BLA BLA....
B: The good thing is, such refining job indicating various device
platforms, could be finished inside the AOO existing framework and
formatting process, only with the external works on supplying above
definitions.

========================

To Rory:
In my point, now, we may need not to specify the exact target we are aimed
at. For although the detailed specification of every type of popular
devices we faced are different, the problems need to be clarified and
solved are commonly the same type of issue, is that "Adaptability and
Fidelity, which is bigger". Definitely, it is an UX issue, which should let
KG to be involved in; But, a given solution for the issue should be
workable for all the devices (of cause maybe including annoy duplicated
works, but should sharing the same working path and steps), whatever the
decision will be.

Ah, yes, maybe we let the new comers confused in some degree. So should we
keep on going within a new thread? Or renaming the current one?

Thanks.

In this discussion it is important to specify clearly which Kindle is the target device, as the screen ratio and pixel count varies from device to device with the newer Kindles.  A stranger coming to this discussion might assume that Kindle genericly refers to the normal "reading" Kindle, with an 800h x 600w screen, which is the common Kindle in use.

Is it possible to have choices? Keep the original page aspect ratio and
scroll (Never used a kindle so not sure if it can scroll but obviously
Android on phones can!) or have a "fit to aspect" where the page is scaled
to the kindle in AOO befor export. If one of the pre-defined page templates
in AOO was the kindle page size it would be possible to reformat the pages
in a document to that size just as you can change from say A4 to US letter.
Probably for complex documents with graphics this would break some parts of
the layout but for the sort of text only novels etc mostly used on these
devices it should work well enough. This assumes you can export to
epub/mobi format in any scale but I'm assuming that will be similar to
export to pdf. Of course the resulting document layout could be checked by
viewing the epub/mobi output. Having an odf viewer for the mobile devices
would be an alternative method and probably less constrained than using
epub formats but it is also more work to do it. OTOH a versatile odf reader
for mobile devices could be very useful in helping establish odf as the
open standard for all types of document.

Re: Apache and ODF

Posted by Fan Zheng <zh...@gmail.com>.
Hi, All:

I am confused about the UX specifications of document representation
requirement on mobile devices, that which is the most first important point
should be, the different device condition adaptability of layout result? or
the fidelity of the document originally recorded?

For example. An ODT format text document with several pages sized as
"Letter", which is physically defined as 279:216 (ratio as 1.29), and user
want to render it in a Kindle Fire, which supplies a 1024:600 (ratio as
1.71) screen for presenting. If we do much more care about the adaptability
of representation, lots data recorded inside the file will be changed,
removed or even ignored. But, if we care about the fidelity much more, we
have to record all the document data inside, and rendering it on the
devices dutifully. In the case, all we could do for the UX, is to give some
adjustable scale.  Such differences are meaning not only the pagination
stuff, but also some solid data inside: thinking about a full
page-width-size table for instance.

Of cause, all the former document editor/viewer applications for desktop,
will obey the "Keep Fidelity" as the very first rule. But what about the
mobile device platforms?

As such differences will actually lead the solution into the different
direction, we maybe should make it clear before having a deeper discussion.

Thanks.

Thank you. I know about the converters. The problem is that all our
office documents are ODF documents. The Kindle device does not provide
any access to our documents until they have been converted by some other
device.

The ODF Toolkit is a Java library for manipulating ODF documents.  A
classic use would be document automation, e.g., taking a document
template and filling in data from a database, to create a new ODF
document.  It does this all without any GUI, no OpenOffice required.
It is not an editor, not a viewer.  It has no rendering, layout or
calculation logic.  It operates directly on the document file.

So ordinarily I'd say that this was not appropriate for a document
viewer, certainly not without a layout engine.  But on something like
the Kindle, with relatively simple layout requirements, the ODF
Toolkit would be analogous to POI, and would make the task far easier.

If you search for it, you will find various solutions for converting
ODF to EPub.  But I have not seen something that does the same for
Kindle's MOBI format.

Greetings,
I wrote a free converter that takes an OpenOffice document (well, LibreOffice)
and converts it to Kindle format.
It's impossible to handle everything from the ODT format, as kindles are more
restrictive, so don't expect a 100% perfect conversion.
You can get it here: http://soft.alkinea.net
It uses kindlegen as the last step in the conversion, to ensure a better
compatibility with all kindles and future Amazon changes.
It's still in beta, but it's rather stable now.
Hope it helps.

As an immediate work-around, Calibre will convert .odf files to almost every ebook format; its formatting is under user control.  Admittedly it would be good if OpenOffice could directly support at least the more frequent ebook formats, without having to rely on an extension to do so.  I remember that there is such an extension, but hae no time to look for the link just now.
