I will read that, but I'm not trying to package stardata catalogs for use by any program, but to package any kind of kstars' data (catalogs, images and DST rules) for use within kstars. It would be a secondary goal to make the catalogs in that set of nine datasets available to other applications, moreover when they are already in the kstars data format. > > > Actually kstars offer each user to download some data, from the net, > > which causes bandwith and disk waste (See #596007).

Would it be better to have users download "source" data catalogs and then transforming them into "binary" useable datfiles? I thought that was the Gentoo way, not Debian's. Anyway, I do not care at the moment on other programs. I will help, if I can, and I undoubtlessy will accept any offered help in packaging these nine dataset (not only catalogs) in any other way that allow them to be used by other programs, but that is far out of my priority, which is having kstars data users on the same computer to download and store kstars data packages only once. > > > * Package name : kstars-data-extra-tycho2 > > > > Version : 1.1r1 > > Upstream Author : Akarsh Simha, Jason Harris <email@example.com> > > The 'upstream authors' of the Tychos2 catalog are not some KDE > developers (with all my respect to their work).

The file I'm packaging has the authors I've expressed in the ITP ad you can see in http://edu.kde.org/kstars/downloads/knewstuff.xml where other datasets are tagged with other authors and licenses. > > > * URL : > > http://edu.kde.org/kstars/downloads/tycho2_mag_12.5-1.1.tar.bz2 > > The URL for the upstream catalog is not correct.

That is the license of the file I'm distributing.

As said, I'm not packaging the original Tycho-2 catalog, but a derivative work on it.

I believe instead that the fact that the catalog is not provided *within* the kstars program is certainly because it is quite big and unnecessary for ocassional use of the program as a home planetarium, since kstars has its own set of predefined stars up to the visual magnitude. Datafile authors (which are, by the way, two of the same authors of the program itself) say the datafile is GPL, so I can not think they decided not to include it because of it being not free. > > Please review the licensing status of the original data files before you > make an upload of this package to Debian.

As said, I'm not interested in astronomy packages in general (false, I'm interested but don't have a damn single minute free), but just on avoiding a very concrete problem I've detected on computers I take care of, namely that the same gigabytes are downloaded and stored several times. Anyway, every help offered to get these datasets ported on to the stardata-common-devel format will be accepted, and if that work starts or if I get more time to package other catalogs (or even use other astronomy programs), I will surely join that mailing list. > > Regards > > Javier Un abrazo Noel er Envite
