[xwiki-users] history of document deletion
Hi, I have a question about XWiki's version control functionality. Q1)document deletion is recorded in the history? Q2)Is it possible to rollback document deletion? Thanks, ebi ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
Re: [xwiki-users] history of document deletion
Vincent, Thank you for your quick response! It would be great if delete and restore operations are also recorded. ebi 2009/12/7 Vincent Massol vinc...@massol.net: On Dec 7, 2009, at 12:39 PM, EBIHARA, Yuichiro wrote: Hi, I have a question about XWiki's version control functionality.

Yes, deleted documents go in the trash, where they can be completely removed or restored.

Re: [xwiki-users] XWiki in Japanese
Hello from Tokyo. As far as I know, XWiki is not so popular in Japan and there is little information written in Japanese about XWiki on the Internet. I could find something if someone were working on Japanese localization. Thanks, ebi 2009/12/3 Jim Grisanzio jim.grisan...@sun.com: Hi ... We use XWiki 1.8 (yes, we're updating soon) for OpenSolaris, and we have a large and active community in Japan. In fact, Japan is the #1 non-English language driving traffic to our site. I notice that Japanese is not supported but these 21 languages are: http://platform.xwiki.org/xwiki/bin/view/Features/I18N So I'd like to find out if anyone is currently working on localizing the XWiki resources file into Japanese. Would I look for that info here? http://l10n.xwiki.org/xwiki/bin/view/XE/XWikiCoreResources Thanks, Jim ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
Re: [xwiki-users] XWiki in Japanese
Jim, I totally agree with you. My XWiki system that I'm currenty working on will go live early next year and I thought I had to localize it to Japanese myself. Please feel free to contact me if there is anything that I can help. Thanks, ebi 2009/12/3 Jim Grisanzio jim.grisan...@sun.com: EBIHARA, Yuichiro wrote: Hello from Tokyo. As far as I know, XWiki is not so popular in Japan It will be. :) and there is little information written in Japanese about XWiki on the Internet. I've been asking around and realize that now. So we have to change that situation, right? For the benefit of the others on this list, the language barriers in Japan are pretty significant, so doing business here and building communities here is challenging using English only. A significant amount of content needs to be localized to really make progress here. So, hopefully, we can get XWiki talking ja soon. :) Jim ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
[xwiki-users] many-to-many relationship with custom mapping
Hi, I'm currently evaluating xwiki. My goal is to develop a data maintenance system for books and authors data. Two entities, BOOK and AUTHOR, have a many-to-many relationship. The new system should provide an ability to maintain the attributes of each entity as well as the relationship between them using forms. There are a large number of existing data, which are sourced from other systems and I'm considering to store them using custom mapping in XWiki. Now I wonder how I should store the many-to-many relationship in XWiki database. Is it a right approach for XWiki to introduce the traditional intersection table? Also, I'd like to know the subsequent steps to follow. I need to create a .hbm file and define a many-to-many mapping, right? And next...? Any hint would be greatly appreciated. Thanks, ebi ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
Re: [xwiki-users] managing very large amount of data
Sergiu, Thank you for your comment. 2009/10/17 Sergiu Dumitriu ser...@xwiki.com: One possible issue I can see is the fact that each entity uses a 64bit hash as its identifier, which can cause collisions. Normally that rarely happens, but as the number of entities increases, so does the chance of it happening. This means that some pairs of document names could not be used at the same time, so you'll have to rename one of them. I'll consider to use auto-number as document name and hide it from user.

Re: [xwiki-users] managing very large amount of data
Guillaume, Ludovic, Thank you for your quick responses and kind advices. What I'm planning is a bibliographical database system. Briefly speaking, the database will finally have 15,000,000+ bibliographical records and 2,000,000+ author records. Both of them have small number of fields (at most 10?) and one long text field that users can freely edit. Since they have N:N relations each other, based on relational model design, the table to store the relations can also become large. Currently, my first option is XWiki and another one is to develop everything from scratch. But I don't like the latter one... Actually, the amount of data may not be very important because the estimated number of concurrent users is quite small. You absolutely need to implement custom mapping from your structures. Otherwise it will be too big. Great! It looks like the very feature I should use! Anyway, I still think XWiki is worth studying further more and I'll start prototyping. Thanks, ebi 2009/10/14 Ludovic Dubost ludo...@xwiki.org: Hi Yuichiro EBIHARA, Yuichiro a écrit : Hi experts, I'm now planning a system that will store 15,000,000+ items of structured data and provide a basic CRUD functionality for them. Nice this sounds like an ambitious project... Are you talking about 1500 pages ? Each page would have how many additional meta data fields ? While XWiki is the first condidate for me for the time being, I'm worried about if XWiki can manage such a large amount of data. Can anyone say the largest XWiki systems? Our largest system is currently Curriki.org.. It's more in the 100K of pages but with large pages (they have many XWiki objects). There is also a big volume 20GB. We have many installations running with that size (mostly because of attachments). Also, I'd also like to know what kinds of considerations are needed to build a large XWiki system. You absolutely need to implement custom mapping from your structures. Otherwise it will be too big. Which database is recommended? MySQL is ok? Is it a good idea to This is a good question. I'm not a mysql specialist and 15 million rows is a lot. Postgres might be a good candidate too for that volume. You should search on the Internet. Depending on your confidentially needs, maybe an XWiki storage implementation over Google App Engine could be a good candidate. It also depends on how much time/spending you have for this application. manually apply MySQL's partitioned table feature to large tables? And Anything that is transparent to the application and that allows good scalability is good others... Any suggestion would be greatly appreciated. There are some things you need to absolutely avoid like showing in one page all the data in a space for example or running a search with rights on a common term. That will clearly not work. and just calling it once could bring down your install. You might want to write a custom rights manager to disable rights altogether if it is an option. I would also suggest that if you have some budget for this project you look into having some support to do it right. Initial choices could be tough to fix with that amount of data. (XWiki SAS provides support http://www.xwiki.com or other experimented developers on this list might be able to help) Ludovic Thanks in advance, ebi ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users -- Ludovic Dubost Blog: http://blog.ludovic.org/ XWiki: http://www.xwiki.com Skype: ldubost GTalk: ldubost ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
