I'd support this -- we could also discuss the "distributed filesystem approach" there. Could this happen between Friday (DebCamp) and Tuesday? I have to leave on Wednesday... For the specified package (astrometry.net), I have been looking into the content of the packages, and I think I can make a compromise here: The tables mainly contain star positions, and the tables range sizes range from brightest 1000 stars (for the smallest table) to ~200 million stars, roughly doubling with each table. Already the first 12 tables are quite useful for many applications (not for my instrument, however :-( ), covering 1.45 million stars, and have a size of 114 MB; I think this is acceptable for a Debian package. However, there may be a licensing issue: The data are officially under GPL-2+; but this is sort-of impossible: GPL requires to have the "sources" available (and defines source as "the format that a human prefers to edit" or so). There is no such "source" for these files: they come from an survey (2MASS) and the final "source" are the positions of the stars on the sky. These positions are obviously not editable by humans yet :-) And while the process of generating the star catalogs is somehow documented, I doubt that we can or should reproduce the catalogs from the original exposures in Debian -- this would require disk space, computing power and man power which we obviously don't have. And the files have a quite straight-forward, documented structure so that anyone could patch them if needed. So, I would take these files (despite the fact that they are *generated* by another program) as source files. Maybe we could discuss this as well at the Debconf? At some point we should think about how to get this in our Social Contract. Best Ole -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
