Forum:Semantic MediaWiki update

So Semantic Mediawiki 1.0 is out... and is on test at Wikia! Anyone interested in testing it, please email me at sannse@gmail.com or ping me on IRC, and I'll give you the link. If all goes well, I hope that we can have this extension on all of Wikia's wikis. -- sannse (talk) 17:58, 10 January 2008 (UTC)
 * What's the good place to discuss issues with Semantic Mediawiki on the test wikia? --Lirielle 08:37, 27 January 2008 (UTC)
 * Here's fine... what have you found? -- sannse (talk) 21:47, 28 January 2008 (UTC)
 * I was about to comment about n-ary properties not being implemented but when I went back to the wikia today, all the Semantic support seems to have disappeared?? --Lirielle 10:51, 8 February 2008 (UTC)
 * It's on again now - the problems with test wikis ;) -- sannse (talk) 11:43, 8 February 2008 (UTC)

1st questions
--Lirielle 21:23, 9 February 2008 (UTC)
 * n-ary properties don't seem to be implemented. What arre the plans?
 * inline queries: doesn't seem to work, when 'old' syntax does . I wonder: is our version an old one or is the doc updated to an unreleased version??


 * Ontoworld is running a latest, devel version of SMW. Could you please check if they have (a) n-ary properties (b) {[#ask:}} syntax there? I'll try to install a devel version if you succeed with either one. -- Nef (talk) 22:58, 9 February 2008 (UTC)


 * n-ary relations are illustrated on their Einstein page, which I copied to the test wikia.--Lirielle 03:39, 10 February 2008 (UTC)


 * those are not n-ary relations! &mdash; MovGP0 02:11, 19 March 2008 (UTC)

fp007 is running SMW code straight from MW repository. (Last change: 2008-02-09.) Could you please test it against this two issues? -- Nef (talk) 19:00, 11 February 2008 (UTC)


 * The inline queries   is working now.  Will test n-ary properties later. -PanSola 20:02, 21 February 2008 (UTC)


 * N-ary relations are also functional now. -PanSola 20:21, 21 February 2008 (UTC)


 * no - they aren't. n-ary relations are not implemented in SMW. There are just 'combined' types that are described as "n-ary", but they aren't. &mdash; MovGP0 02:11, 19 March 2008 (UTC)

Type:Number vs Type:Integer/Float
The official documentation says that in SMW 1.0, Type:Number is going to replace Type:Integer and Type:Float. However, on current installations we have, Type:Number is not yet recognized, while Type:Integer still works. -PanSola 02:49, 18 February 2008 (UTC)


 * I've upgraded SMW on fp007 to the latest version from MW repo. Pls check it now. -- Nef (talk) 17:28, 21 February 2008 (UTC)
 * Resolved, thanks! -PanSola 19:01, 21 February 2008 (UTC)

Its (a)live!
SMW is enabled on Psychology Wiki (stats). Please drop by, help them set up basic properties/relationships, learn a thing or two yourself, and... request it for your wiki! -- Nef (talk) 12:13, 12 March 2008 (UTC)


 * Pls. visit http://semantic-mediawiki.org/wiki/Help:User_manual for info about SMW. -- Nef (talk) 13:21, 12 March 2008 (UTC)


 * I'm really not sure how this thing could be usefull on fr.guildwars. I think i'll start a discussion there to see what uses we could make of this but we are so few users that it wont help us if we have to edit many pages to take advantage of the new features. — TulipVorlax 01:29, 13 March 2008 (UTC)

SMW is enabled on these Wikia projects
See the list (and add your own if it has SMW) at Help:Semantic MediaWiki

Awesome, welcome, join semediawiki-user, I can help
This is a great development! -- Skierpage (Semantic MediaWiki junior developer, doc writer, ontoworld.org janitor 00:48), 13 March 2008 (UTC)
 * If your wikia wiki uses SMW, please update http://ontoworld.org/wiki/Sites_using_Semantic_MediaWiki.
 * If you have questions, the semediawiki-user mailing list is a great resource.
 * You can also e-mail me. It's best to e-mail me a link to a wiki talk page with your problem.  I'm "info"  on skierpage.com.  I'm not sure how to monitor all use of Semantic MediaWiki on wikia.


 * It's a tad too soon, i think there only a couple of Wikia using it. — TulipVorlax 01:29, 13 March 2008 (UTC)


 * I'll keep this thread up to date with info about wiki with SMW enabled. -- Nef (talk) 12:10, 13 March 2008 (UTC)

Learning by example
SMW is a general-purpose extension that has a great number of possible applications. To get the idea, and to use it in a productive way, it is helpful to look at some reasonably well-done example wikis. So here are some that might be inspiring to learn from:


 * ontoworld.org – a wiki used on research-related events; see e.g. the page on ISWC-2006 with SMW-generated workshop timeline.
 * discoursedb.org – strongly structured, database-like wiki; most overview pages built completely automatically from short wiki pages; heavy use of templates (and semantic forms)
 * korrekt.org – personal homepage (one-user-wiki) with SMW-based blog and publication database
 * semantic-mediawiki.org – SMW homepage, using SMW to maintain multi-lingual content in one wiki (see e.g. the bottom of this intro page)

 * Isn't there anything in french ? Lol. I think it would help my users to find this usefull. — TulipVorlax 16:28, 13 March 2008 (UTC)


 * Translation is in progress. Visit this page as a starting point. --Avatar 17:35, 13 March 2008 (UTC)

How can you tell?
I'm sure the answer will be obvious, but it has eluded me. How can I tell whether a wiki I'm working on already has the SMW extension enabled?
 * Try checking Special:Version; the extension should be listed there if it has been enabled. --Michaeldsuarez (Talk) (Deeds) 17:59, 11 March 2009 (UTC)
 * Aha! That's it - thank you :) Elwynd 20:20, 11 March 2009 (UTC)
 * You're welcome. --Michaeldsuarez (Talk) (Deeds) 23:37, 11 March 2009 (UTC)

Is SMW a solution in search of a problem?
That title may sound provocative but I am actually being sincere. In the past I have read Dantman's enthusiastic praises of SMW and I have waded through documentation (very dry) and browsed wikis that purport to use the SMW extension but I just fail to understand what the virtues of SMW are. WHen I think I understand what those virtues might be I fail to find examples of that in poster-child wiki applications that are touted as "utilizing SMW extensions".


 * I suppose I need some very specific links (and possibly some commentary to highlight what it is I am looking at) and not just a vague, "go check out that wiki," because when I do 'check out that wiki' I am sorry to report that the virtues of SMW are not at all obvious. ... am I the only person who feels this way?


 * I think I might want to use SMW :I very much appreciate how complex
 * (i) managing a database of game data and
 * (ii) displaying portions of that data
 * can become when implemented using templates. I took that approach with rappelz.wikia.com (skill data templates and skill presentation templates). That was my first wiki experience and I felt I should crawl before I walked. 12 months later I am tackling a brand new wiki community (vsk.wikia.com) and I can imagine a different kind of database becoming useful. I think I am ready to progress from walking to at least a jog if not a run!


 * So am asking the big question:
 * should I learn SMW and use it or should I muddle along with templates again?

Guided by the list of wikis mentioned in this thread and at I visited each one to try to understand and appreciate the virtues of using SMW. Whatever those virtues may be they simply do not jump out of the page and announce themselves.
 * I reviewed the history of changes and notice that changes are not very frequent or even recent on some example wikis.
 * I pick on a few articles to examine the revision history - no clues there either.
 * I do the same for a category or two - still no joy!
 * I search the forum if they have one for any reference to SMW - again no evidence of SMW hemoglobin coursing through the veins of the subject wiki.

Without a doubt I must be looking at the wrong pages or searching for the wrong things.


 * 1) What exactly is the problem that SMW is meant to solve?
 * 2) Where are the application notes?
 * 3) Is there a quick start tutorial to review?
 * 4) Where's the beef?

All jesting aside, I am genuinely wanting to understand how SMW could help with this new wiki. Possible ideas I have include:
 * 1) There is a rule book (the ISAF RRS) that has about 20 or 30 relevant rules that apply to the game in question. The interpretation of those rules for a real life sailboat race is not always precisely the same as the way the rule is interpreted in the game. So it seems there could be lively discussion about this interpretation and the possibility of fracturing the rule book into a database entry for each rule or each section of each rule may or may not have some benefit in this regard.
 * 2) The users who play the game play on public servers hosted by other members. As such there is no central game server and no permanent database of users where such information as past race results sailing different types of boat or different race course can be stored. So I speculate that maybe a wiki community hosting such a data base might allow some clever things to be done in that area such as recording the fastest completion time for each course for some range of wind speed or wave height. Perhaps a link to the favorite boat "skin" used by each user can be stored in that database so other players can remind themselves who was who.
 * 3) Scoring the results of a each race seems like a perfectly good use for a database whether or not those results are automatically populated via a script or manually loaded by a patient community member.
 * 4) Each class of sailboat has performance characteristics shared by an skipper of that same class of boat. Currently that data is not well documented and so a wiki hosted database might lead to a better collection of documentation of this performance data.

So there you have it a few possible problems looking for solutions or a solution.


 * The question is : does SMW have anything to offer this set of applications?

 * "Is there a quick start tutorial to review?" - every Wikia should have "shared help" called Help:Semantic MediaWiki (mentioned above). — Robin Patterson (Talk) 11:50, 14 June 2009 (UTC)

SMW is solving huge problems on the Genealogy Wikia
See the bottom two or three screenfuls of Genealogy:Forum:SMW. Understandable that Najevi didn't check out that wiki. It wasn't on "the list of wikis mentioned in this thread" because it had no SMW seven weeks ago. The wiki can now take off. I think it has passed the NASCAR Wikia (whose new name I forget - Third Turn? - and which by the way might give User:Najevi some specific help). It's set for world domination (if you believe User:Phlox; I tend to). — Robin Patterson (Talk) 11:50, 14 June 2009 (UTC)
