Has anybody integrated any of MIT's open source "Project Simile" ( http://code.google.com/p/simile-widgets/ ) JS widgetry into Xwiki? For example their http://simile.mit.edu/timeline/ http://simile.mit.edu/timeplot/ or http://simile.mit.edu/timegrid/ ?? This has been discussed previously on these lists: http://markmail.org/message/bds6fein6w4ftqot#query:MIT%20Simile%20Xwiki+pag… http://markmail.org/message/bds6fein6w4ftqot#query:MIT%20Simile%20Xwiki+pag… http://markmail.org/message/bds6fein6w4ftqot#query:MIT%20Simile%20Xwiki+pag… http://markmail.org/message/bds6fein6w4ftqot#query:MIT%20Simile%20Xwiki+pag… http://markmail.org/message/bds6fein6w4ftqot#query:MIT%20Simile%20Xwiki+pag… Unfortunately, all the emails mention example links that no longer exist, so there's no obvious Xwiki examples providing Simile widgetry in Xwiki ... FYI, Other environments have integrated some of the MIT functionality: http://drupal.org/project/timeline http://drupal.org/project/exhibit http://simile.mit.edu/wiki/Wibbit Niels http://nielsmayer.com

Hi, I've played quite a lot with Simile Timeline in the past. I've made a little snippet showing last modifications within the wiki on code.xwiki.org : http://code.xwiki.org/xwiki/bin/view/Snippets/TimelineSnippet In action: http://incubator.myxwiki.org/xwiki/bin/view/Main/Timeline JV.

FYI, I've updated and commented the Timeline example ( http://code.xwiki.org/xwiki/bin/view/Snippets/TimelineSnippet ) in preparation of my nefarious deconstruction of the widget into a novel interface for a totally different form of usage ... working example: http://nielsmayer.com/xwiki/bin/view/Timeline/TL2 sources: http://nielsmayer.com/xwiki/bin/view/Timeline/TL2?viewer=code & http://nielsmayer.com/xwiki/bin/view/Timeline/ChangesList?viewer=code Next steps is to remove this constraint (suggested in http://code.xwiki.org/xwiki/bin/view/Snippets/TimelineSnippet ). If you forget to do this, nothing works; yet, adding it is quite annoying and shouldn't be needed:

...

Prerequisites You must add this line: <script src="http://simile.mit.edu/timeline/api/timeline-api.js" type="text/javascript"></script> At the bottom of the "HTTP Meta Information" field in *Administration* > * Presentation*.

Seems like the following links are good starting points for a solution to the above issue: Installing MIT Simile's Timeline locally (w/ Rails integration) | Ryan Kanno: The diary of an Enginerd in Hawaii<http://blog.localkinegrinds.com/2007/11/06/installing-mit-similes… Message <http://simile.mit.edu/mail/ReadMsg?listId=10&msgId=19202> & Message<http://simile.mit.edu/mail/ReadMsg?listId=10&msgId=19199>=19199>... This entails installing a local copy of the timeline javascript and modifying a few lines of source. Othewise, with the existing solution, you're stuck with loading the simile javascript for any page on your site, slowing down the initial load time even more with yet more global javascript that never gets called in most situations. (Alternately, perhaps catenating all the timeline javascript and shoving it into a single xwiki doc or template that gets included only in a timeline-using app). -- Niels http://nielsmayer.com PS: I think it would be interesting to put extra attributes on certain sets of documents, and then sql-query for those documents with those attributes and present them in the timeline. That way, for example, one could render a sequence of steps over time, where each step is a xwiki doc. There's no reason why the horizontal axis needs to represent discrete time. It can represent any monotonically increasing sequence. For example, editing the sequence of steps and concurrent streaming media for purposes of making a movie or real-time presentation composed from wiki components. PPS: http://en.wikibooks.org/wiki/XQuery/DBpedia_with_SPARQL_and_Simile_Timeline… another interesting application of the Timeline widget. It would be interesting if xwiki could support SPARQL ( http://www.w3.org/TR/rdf-sparql-XMLres/ ). The timeline widget doesn't necessarily need to be used as a timeline... you could also use it to present complex database result sets laid out in two-dimensions, for example (e.g. search hits presented over topic and confidence in matching.).

Hi, Please, must I expect that the timeline snippet or the modifications proposed by Niels work fine in a 1.3.8295 XWiki Enterprise. Sorry, I now that I must update this server... Thanks for your help, Ricardo Niels Mayer wrote:

(1) check to see whether the affected tables and queries in the timeline example are actually *in* your database and that the schema hasn't changed (any xwiki experts feel free to chime in on whether this is or isn't the problem -- tho I'm pretty sure that doc.space was in 1.3...). ... and if it's not a db schema issue ... (2) It also might be a variant of the problem i found with inappropriate characters in documents, spaces and "subject/titles" thereof. Your error is:

Do any of your spaces (or document names) have inappropriate characters, like `` ' '' or `` " ' For some reason these don't necessarily get noticed (to the point of creating problems that pop up backtraces), until you run the timeline: http://jira.xwiki.org/jira/browse/XE-376 ( characters entered as document title must be escaped or a cascade of bugs occur ). Edit/save the offending document even "fixes" em -- with lossage of all characters after first ' " ' And all it takes is one document with one such character to make the Timeline blow up. The extra quotes could be in some innocent document made years ago... but if you accidentally "quoted a phrase" in a subject somewhere it triggers the error. Solution: use two single quotes, e.g. ``quoted a phrase'' ... I'm Stating #2 on remote chance my intuituion on this is correct. I didn't spend much time looking at your site to find such docs, etc...just got the error backtrace and noticed the oddness of it.

Hi Niels, Thank you for your insight. I am almost sure that doc names and spaces have not inappropriate characters, but I can not be so sure about titles. My first trial following your message has been to test your code in a XWIKI ENTERPRISE 1.7-MILESTONE-3.14362 It worked without a glitch. Of course this not solve the doubt if the reason for the failure is in the contents. I think that is time to face the update process with this server and eliminate some possible causes. I need to reach the end of February with this installation untouched. I will be move then to XE 1.7.3. I will be back ASAP! Best, Ricardo Niels Mayer wrote:

There's no such thing as XE 1.7.3 yet :) There's a 1.7.1 and maybe there'll be a 1.7.2 (not planned yet). Since XE 1.8 final is planned for early March I'd suggest you move to XE 1.8RC1 or RC2 at that time. Thanks -Vincent
