Hi Madeleine, Madeleine Price Ball schrieb: > I was curious if you include images? If not, are you considering doing > so, and what's stopping you? If so, how do you pick them? we haven't done this on our "Test DVD" this summer even though this is easily possible. Well, easily means: It is easy for the format, but the problem is to choose the images. Emmanuel Engelhart (Kiwix, he is also part of the openZIM team) has made some perl scripts for that. We didn't do it for two reasons: Lack of time, because even though the tools exist, it's a lot of work. Searching through the articles, get all the image URLs, get the images, decide in which size to resize them etc... And the openZIM project is not a publisher of offline content. We are developing a stable, efficient format allowing free interchange of contents between reader applications and devices and providing a GPL'ed sample implementation of it. > I did the work for picking which articles & images went into the XO > activity, based on traffic stats.

Well, we had a "Offline Meeting" at Wikimania in Buenos Aires this summer where Samuel Klein was also participating. Our goal is to contribute the right technology to make all the offline projects able to collaborate. Currently everyone is reinventing the wheel when it comes to storage of the content. We think that the specific knowledge of the publishers should be how to select the content - which content goes where in which form - and not technical questions such as compression, storage or retrieving the data on the user's end. Wikimedia Foundation is supporting us so far as they share our goal and work on a regular export of all Wikimedia wikis into ZIM format (like you already get SQL and XML dumps on download.wikimedia.org). They also have a lots of contacts whith publishers and other projects working on Wikipedia Offline and connect them with us, so we can improve ZIM to fit for all the Wikipedia Offline projects. That's why we defined a new format version at the last Developers Meeting.

Jimbo - thanks for the spur to clean up the existing work. All - Let's start by cleaning up the mailing lists and setting a few short-term goals :-) It's a good sign that we have both charity and love converging to make something happen. * For all-platform all-purpose wikireaders, let's use offline-l(a)lists.wikimedia, as we discussed a month ago in the aftermath of Wikimania (Erik, were you going to set this up? I think we agreed to deprecate wiki-offline-reader-l and replace it with offline-l.) * For wikireaders such as WikiBrowse and Infoslicer on the XO, please continue to use wikireader(a)lists.laptop I would like to see WikiBrowse become the 'sugarized' version of a reader that combines the best of that and the openZim work. A standalone DVD or USB drive that comes with its own search tools would be another version of the same. As far as merging codebases goes, I don't think the WikiBrowse developers are invested in the name. I think we have a good first cut at selecting articles, weeding out stubs, and including thumbnail images. Maybe someone working on openZim can suggest how to merge the search processes, and that file format seems unambiguously better. Kul - perhaps part of the work you've been helping along for standalone usb-key snapshots would be useful here. Please continue to update this page with your thoughts and progress! http://meta.wikimedia.org/wiki/Offline_readers SJ 2009/10/23 Iris Fernández <irisfernandez(a)gmail.com> > On Fri, Oct 23, 2009 at 1:37 PM, Jimmy Wales <jwales(a)wikia-inc.com> wrote: > > > > My dream is quite simple: a DVD that can be shipped to millions of people > with an all-free-software solution for reading Wikipedia in Spanish.

You could help with a new version of that page. Madeleine (copied here) worked on the first one, but your thoughts on improving it would be welcome.

[openZIM dev-l] new branch for openzim created
by Tommi Mäkitalo 29 Nov '09

29 Nov '09

Hi, I just created a branch for the changes in zim format, we discussed at our developer meeting. The branch is located in our repository under branches/zim2. I already checked in first changes. qunicode is removed from zimlib. Also distinqushing between url and title is started. I also decided to change the zint compression. The compression is now similar to utf-8 and saves a little space compared to the old algorithm (about 2%). The zint compression is used in the full text index currently. We already discussed about using it in the directory entry also to save some bytes. I'm not sure if it worth the trouble. It makes alternative implementations more difficult. If alternative implementations do not care about full text index or categories, they don't need to implement the zint compression. On the other hand the code for it is straight forward and should be easy to port. The branch is not working yet. It may take some time until it will since I have to implement the changes in the reader as well as the writer before I can even start testing (other than verify, that it compiles). It was easier with zeno when I started, since I had already working zeno files. Tommi

That's confirm a few things: * The wikipedia_en_wp1_0.7_30000+_05_2009_beta2 is only a beta and should be improved and I will do it soon. * I need to code a perl script to check many thing in a HTML directory (https://sourceforge.net/tracker/?func=detail&aid=2901059&group_id=175508&at…) before building the ZIM * I think we need such a tool (zim-check?) in C++ coded to be able to do the same with ZIM files (I see that pretty necessary if we want to setup a ZIM Library: nobody want that we spread bad quality ZIM) http://bugs.openzim.org/show_bug.cgi?id=14 As soon as I will have finished with that stuff I will publish a new version of the ZIM file and contact Tom.

[openZIM dev-l] zeno, zim formats
by Andy Rabagliati 20 Nov '09

20 Nov '09

Folks, Coming here by way of the Wikipedia:Version 1.0 Editorial Team pages, I have a few questions. Disclaimer :- I am in South Africa, where bandwidth is expensive, so a lot of my 'fiddling' is done on my server in the USA, where I do not have b/w limitations. My interest is to be able to serve wikipedia content off a server in a classroom - usually a Thin Client setup, but not always, and they rarely have internet access. Weak, small clients, networked to a strong server, running linux. I downloaded a torrent - en.wikipedia.okawix - which appeared to be a tarball with these contents :- -rw-r--r-- 1 andyr andyr 571428918 Jul 6 23:24 article.index -rw-r--r-- 1 andyr andyr 108812163 Jul 6 23:24 article.map -rw-r--r-- 1 andyr andyr 5601891132 Jul 6 23:23 en.wikipedia.zeno -rw-r--r-- 1 andyr andyr 11 Jun 23 18:58 entry.url -rw-r--r-- 1 andyr andyr 307 Jul 6 23:23 licence.xml -rw-r--r-- 1 andyr andyr 596303890 Jul 6 23:25 word.index -rw-r--r-- 1 andyr andyr 108108941 Jul 6 23:25 word.map I see a zeno file - a precursor to the zim format ? The ZimReader static binary from http://openzim.org/Releases dated 2009-06-07 (same date as the files above ?) will not read the file. Am I doing this wrong ? Secondly, I downloaded wikipedia_en_wp1_0.7_30000+_05_2009_beta2.zim and pointed the ZimReader at this - hoping to browse to server:8080 and read the file. But I have no index, and no search - do I need to get the index files separately ? And the css files (?) are in German - do I need to compile my own reader from svn to get an English reader ? Can I build a deb (for Ubuntu ?) Cheers, Andy!

I think this is a very important point: Having a good solution is at least as important as making it available and easy to use. I'm currently working on the Kiwix deb package and I have had to integrate the zimlib code in my source because there is no package. Hope we will be able to find a deb maintainer able to setup and keep uptodate deb packages of the zimlib, zimtools and tntzimreader. In the worth case, I will do it, but I'm a newbie in deb packaging and the whole stuff may need a few months. Regards Emmanuel

[openZIM dev-l] Compiling zimreader/writer

I would like to check out how well zimreader will serve a zim file via http. I am compiling zimreader and writer from svn. Ubuntu karmic has libcxxtools-dev version 1.4.8-3 and libtntdb-dev version 1.0.1-3 and libtntnet-dev version 1.6.3-4 If I use those, zimwriter throws up errors filesource.cpp: In member function virtual bool zim::writer::FileArticle::isRedirect() const: filesource.cpp:55: error: CXXTOOLS_ERROR_MSG was not declared in this scope Zimreader compiles OK Another question - is there a *small* zim file anywhere I can use ?? Cheers, Andy!

[openZIM dev-l] Developers Meeting - when do you arrive?
by Manuel Schneider 18 Nov '09

18 Nov '09

Hi all, it is Wednesday already and the Developers Meeting is just two days away. Hotel rooms are booked at the same place as last time. As we are so many participants we didn't have a chance to realise the idea we had the last time with renting an appartement with space to sleep, accommodation and internet access. There were no appartements that were big enough and provided everything we need. So we will be at the same hotel (Hotel Löwen, Gündenhausen 16, 79650 Schopfheim, +49 7622 688499-0) and at the same venue (Tranter HES, Hohe-Flum-Strasse 31, 79650 Schopfheim, 300m from Hotel Löwen). Many of you already gave me their itineraries, so I can arrange pick-up from airport or advise how to get to the hotel. If you need help please contact me now. Anyway it would be good if you could tell me when you arrive and when you will depart - or just add it yourself in the wiki: http://openzim.org/Developer_Meetings/2009-2#Participants We meet on Friday at Tranter HES, those I pick-up somewhere I will bring there, after 20:00 we will go over to the hotel. So if you come later than 20:00 go directly to the hotel. The hotel rooms are book on your name but already paid by me, these cost will be covered by the openZIM budget. There is breakfast at the hotel included. We will have dinner at Hotel Löwen on Friday and there will be a buffet available all day at the venue, both is covered by openZIM. To help us with our tight budget Tomasz managed to get another dinner covered by the Wikimedia Foundation (except alcoholic beverages), we will have that on Saturday night. Emergency phone numbers: Manuel: +49 160 90803992 Annette: +49 170 7740589 Have a good trip!
