Hi!
It has been asked multiple times at [[commons:Commons talk:File types]] to enable OpenOffice.org 2.0 formats (=OASIS OpenDocument Format) for file upload. Any objections? Can you please enable it?
Filename extensions are .odt (text), .ods (spreadsheet), .odp (presentation), and .odg (graphics), then there is .odc (chart), .odf (formula), .odb (database), .odi (image), and the according templates .ott, .ots, .otp, .otg, .otc, otf, .oti and finally .odm (text-master) (see http://docs.oasis-open.org/office/v1.0/OpenDocument-v1.0-os.pdf appendix C, page 697f.)
Greetings, Jakob
