Hi :)
Ahh, ok :)  That makes sense now.

It is, of course, possible to put several Odt documents inside another
zipped file and that should benefit from the higher compression rate.

I guess the "feature request" would be passed on to the OASIS
committee but it sounds like they have probably already weighed-up the
pros-and-cons
Regards from
Tom :)

Hi Frank,

 I think you could significantly improve the compression on the odt docs.

tar -c dir | xz -4 -e >> file.tar.xz

16,760 tar.xz
21,919 odt

76.46334230576213%


there is no choice, how to compress the package, because it is defined in
the standard, see http://docs.oasis-open.org/office/v1.2/os/OpenDocument-
v1.2-os-part3.html#__RefHeading__752789_826425813


Agreed.
It *is* possible to achieve better compression than ZIP (we knew how to do
that for quite some time ;) ), but to do so we would need a new iteration
of the OpenDocument standard. While it's not totally out of question, I
have the feeling that increasing fragmentation just to save space on office
files is not a good trade-off. Remember that ODT files are used by many
pieces of software, not only LibreOffice.
OpenOffice of course, but some part of google export, some less-known
office suite, various custom software that output their reports as odt
files... even mso got to implement it. I doubt a new version of the
standard would be a good thing while it is still functionnal.
