DPL Extension
Hi Christoph,

Could you install the "Dynamic Page Links" extension (with the "Call" extension as well)? Full instructions are located at. This extension can be used to create some advanced user-interactive search features. -- Marty 19:35, 30 September 2007 (CEST)
 * Hi Marty, it should work now, please check. Yes, I've read a little bit about DPL on the Semantic MediaWiki list, and I think that you can utilize it quite well. Best, Christoph 00:10, 2 October 2007 (CEST)

Update Semantic Forms
Hi Christpoh, Thanks for the advice on license/copyright issues. I think I've taken care of the problems. Could you update Semantic Forms to version 0.6 when you get the chance? There's a small bug that affects my forms. Best, Marty 21:31, 12 September 2007 (CEST)
 * Done, should work now. I didn't notice that a new version appeared. I any such case, just tell me. --Christoph 00:06, 13 September 2007 (CEST)

Uploading a few picture files
Hi Christoph, Thank you for the admin priveleges -- I've deleted some old pages, and cleaned things up considerably. I would like to be able to upload a few small picture files to accompany problems and some geometry content. I tried to upload a PNG file, but I got an error message -- perhaps there is no public upload access. Any ideas? I also have an SVG file which I would like to use, if this is better. Thanks! Marty 20:22, 10 September 2007 (CEST)
 * Argh, one more problem that I re-introduced during the MediaWiki upgrade. Should be fixed now, thanks for pointing out. --Christoph 21:12, 10 September 2007 (CEST)

Admin Priveleges?
Hi Christoph, Could I have the admin priveleges? I think they would be useful, mostly for deleting some pages as I undertake some cleanup of my project. Thanks, Marty 18:00, 7 September 2007 (CEST)
 * Sorry, I was away and offline over the weekend. You have the privileges now – enjoy, Christoph 13:03, 10 September 2007 (CEST)

Math texvc problem?
I'm getting an error message, with mediawiki parsing things in the math environment. The error message is "Failed to parse (Missing texvc executable; please see math/README to configure.): y = 2 x + 5", and it appears on the page Faceted_Curriculum_Project/Standard_Directory/US_IN/A2.2.1.

Any ideas? I'm pretty sure I input the math in the correct format. Thanks, Marty 19:27, 6 September 2007 (CEST)
 * Your syntax is correct. It's just that the TeX to PNG converter texvc has got lost during my MediaWiki upgrade :-/ It should work now.

Error message, using the Semantic Forms Extension
I'm getting an error message when using the Semantic Forms tab "Edit with form" tab. It is very possible that the problem is with the extension, but I thought you should know about it. The error message is: "Warning: preg_match [function.preg-match]: Unknown modifier 't' in /var/www/kwark/w/extensions/SemanticForms/includes/SF_FormPrinter.inc on line 156".

I've posted this on the Semantic Forms discussion board, but let me know if there might be a reason on the mathweb.org end. Thanks! -- Marty 04:24, 6 September 2007 (CEST)
 * I fixed it, according to Yaron's instructions. (As I'm not subscribed to that group, could you thank him on my behalf?) Google is quite fast in updating the search indices of their own sites: When I googled for the error message, I found the groups thread with your question and Yaron's reply how to fix it :-)
 * BTW, to exclude other sources of errors, I've also upgraded MediaWiki to the most recent version (1.11.0rc1). --Christoph 11:27, 6 September 2007 (CEST)
 * Thanks! I'm quite impressed with the speed in which these things are getting done!  Marty 19:27, 6 September 2007 (CEST)
 * To be honest, this will not always be the case, when I'm busy with other things. But right now, I'm impressed by your progress and infected by your energy :-) --Christoph 19:54, 6 September 2007 (CEST)
 * My progress will also slow down considerably when I get busy teaching again (September 27, I think). That's why I'm trying to move so fast now! -- Marty 21:38, 6 September 2007 (CEST)

Namespace Question
Hi Christoph, I've been trying to keep the FCP-related pages in their own directory, to keep things from getting too cluttered. But, perhaps there should be a separate FCP namespace? What is your opinion of arranging files in a directory tree with semantic mediawiki? On the one hand, a directory tree is somewhat unnecessary, if semantic information is sufficient to find pages. On the other hand, a directory tree might help with portability. Do you think there should be further subdirectories of the FCP directory as well, or is this not recommended?

Let me know what you think about keeping pages organized. I'll be happy to follow your guidelines. -- Marty 00:25, 6 September 2007 (CEST)
 * Hi Marty, I understand your concerns. Sure, I could create an additional FCP namespace, but I'm not sure whether that would help. Currently, the FCP page has already four sub-directories (Block Directory, Blocks, Standards Directory, Standards), if I understand your layout correctly. That is, one namespace would not be sufficient, and hierarchical namespaces are not possible. Therefore, I'd stick to directories. I don't have any objections against them. (Except that they might cause some weird problems – after all, the above problem with the SemanticForms extension was due to directories. But that should not happen in general.) On the contrary, I like directories and think they are appropriate in your setting. --Christoph 11:37, 6 September 2007 (CEST)

Semantic Forms Extension
Hi Christoph, Could you also install the SemanticForms extension? A description can be found at. It seems pretty well-developed and is made to work with semantic mediawiki. Thanks, Marty 18:52, 5 September 2007 (CEST)
 * Done. That's a good way to make me learn about nice extensions -- keep it up! I'm eager to learn how to use them productively. --Christoph 19:07, 5 September 2007 (CEST)

Inputbox Extension
Hi Christoph, Could you install the inputbox extension? I'd like to use it to automate the creation of new pages based on templates. Thanks, Marty
 * Should work now -- enjoy :-) Christoph 21:18, 4 September 2007 (CEST)
 * Thanks! -- Marty 21:35, 4 September 2007 (CEST)

Wiki Formatting
Moved to Help talk:Contents. --Clange 17:34, 16 April 2007 (CEST)

MathWebSearch
Hi Christopher,

I corrected in the MathWebSearch page the link to Wiris editor, but I'm not sure that this one is still use in the search engine ? BTW does the wiki have an automatic feature to find and help to correct the reference to internal link with similar names (here Wiris and Wiris_Formula_Editor) ? Also how does the synonyms are deal with ?

Fred
 * Hi Fred, I should eventually reply to this… Sorry, it got lost, as I was quite busy with other work during the last few weeks :-/ About the recent activities in the MathWebSearch project I do not know much more than I can see on the web page. (I could ask Michael, though.) Apparently, the Wiris editor applet has been removed, but I know that it had been used there before. We used to have access to the source code for research purposes, but the software is not free. Therefore, the MWS developers (i.e. Ioan and Michael) want to replace it by something else - as far as I know, some JavaScript-based editor developed by Alberto González Palomo (the developer of QMath and Sentido), which is not yet publicly available, though. There used to be a more recent page with a beta version of MWS (http://betasearch.mathweb.org), but currently this is a redirect to the normal MWS page.
 * Concerning your MediaWiki question, I'm not aware of such a feature :-( Synonyms are currently handled with human brute force (i.e. manually identifying them and creating redirects), which works quite well on Wikipedia, but not so well here. Semantic MediaWiki does not add any further support so far. --Clange 01:46, 4 September 2007 (CEST)


 * OK, I had seen that Wiris editor was not free, so I assumed it was why it disappeared... and I was right. Also, Michael mentions Alberto's editor in his OMDoc book, so I had taken a look to the page but did not find how to download the software. Thanks a lot for the clarification. For the synonyms it is a a shame as we have to made manually the pages...
 * As long as there is no public release of Sentido, you could probably ask Alberto to send you a pre-release, by referring to me and to this discussion. --Christoph 19:57, 6 September 2007 (CEST)

Wiki
Hi Christoph,

Thanks for the link, It gave me a better idea of the wiki syntax. Do you know if there are many people that read or contribute to the wiki ?


 * Hi Fred, as you can see from Special:Listusers, there are only a few users so far. (People who just read are not counted, however.) But that may improve soon, as we only opened this wiki for the public last week. BTW, how did you find out about it? --Clange 14:57, 13 February 2007 (CET)

OK, thanks for solving the password problem.

Fred

Users
Hi Christoph,

It seems the plug-in you have installed against spammers works well ! However, the list of user Special:Listusers have not grown a lot and I believe the majority of them are robots. To see clearer, you should delete the users such as Au3F5w, CjsW9d... (and also my former pseudo Fred_wang).

Fred
 * Hi Fred, thanks for your suggestion. That would make sense, but, unfortunately, MediaWiki does not allow to delete user accounts without hacking the database, and currently I don't have the time to do that... --Clange 11:52, 2 August 2007 (CEST)
 * OK.

Chat
Hi Cristoph,

Thanks for posting the announcement about this wiki's reopening at Asteroid Meta. The group over there has forked, in an interesting techno-sociological development (partly resulting from ongoing attacks by spam bots), and the new group links can be seen here:

http://us2.metamath.org:8888/mpegif/mmrecent.html

I have an idea that initially populating the wiki using the source documents from OMDoc and other projects is possible. Otherwise, isn't filling the wiki manually somewhat redundant? For example, what is the purpose of a MathML page here when this is available:

http://en.wikipedia.org/wiki/MathML

I am more of a programmer than a writer, and my interest is reading the wiki...

-MelOCat (aka "Mello")
 * Hi Mello, a short reply:
 * I'll soon have a look at the new MetaMath page; right now, I can't access it :-(
 * populating the wiki – Are you talking about this wiki? – Fine! But mind the license! We have Creative Commons Attribution-Share Alike, and if the previous wiki had an incompatible license (or no license at all), every contributor must agree.
 * MathML on Wikipedia – Yes, but in this wiki, we can use more tech-speak and math-speak, as we can presuppose some knowledge about maths and XML. For example: The ordinary Wikipedia reader wouldn't be interested in MathML validating tools (such links might be deleted there for lack of relevance), but we are. Of course, we need not duplicate Wikipedia's content; but rather link to it and provide additional content here.
 * Cheers, Clange 21:07, 14 February 2007 (CET)

Request For Interwiki
JA: Hi, could you create an interwiki for Centiare? A simple "c" would be easiest, unless that's too short. Gratia in futuro, Jon Awbrey 19:25, 14 September 2007 (CEST)


 * Hi Jon, I've done that. However, I decided to name it "centiare" in order to stay forwards-compatible with adding further relevant interwikis starting with "c". Best, Christoph 19:30, 14 September 2007 (CEST)

JA: Zounds goot, thanx. Jon Awbrey 19:32, 14 September 2007 (CEST)

SVG
Christophe

Thank you for the comments on my talk page. I know something of MathML and have used it a bit. I had come across ChemML but have not used it. Where I could do with some help is with SVG and specifically with ZSVG which is SVG implemented using DTML in Zope. I found some interesting examples the other day at http://www.zope.org/Members/aho/ZSVG_Graph_1_2_0/ZSVG_Graph_1_2_0 and I have been attempting to adapt this without (so far) a lot of success. I will put some more background to my interests on my page at User:fletchjp

John Fletcher

P.S. I now realise the comments came from Fred and I have posted on his discussion page to thank him. --Fletchjp 14:03, 3 January 2008 (CET)

-- I did not know ZSVG, but it looks like a nice tool! I tried the online demo but it did not work... I downloaded the program and I'll play a bit with it. Maybe we can create a new page about SVG and continue this discussion on this page?

Fred

Interwiki again
Is there an interwiki code for mathweb from ontoworld? --Fletchjp 23:04, 4 January 2008 (CET)
 * I don't think so. But I'm sure that Markus, the admin, won't mind adding one. --Christoph 23:08, 4 January 2008 (CET)
 * BTW, I just realised that the interwiki setup for Ontoworld in this wiki was wrong. It's been fixed now. --Christoph 23:12, 4 January 2008 (CET)

The content that used to be at the Centiare wiki has now been moved to the MyWikiBiz wiki, so it might be good to have an interwiki for the new site. Thanks, and Happy 2008. Jon Awbrey 07:18, 5 January 2008 (CET)
 * Done (named mywikibiz) – Thanks, same to you! :-) --Christoph 12:08, 5 January 2008 (CET)

Categories and Properties
As you know I am new to both ontoworld and mathweb. I am trying to sort out how to annotate my work on both wikis, using the categories and properties. I have come to the conclusion that there are some differences between the two wikis when it comes to what works. For example, on one page (SymbolicC++) I have used author while on ontoworld there is a preference for has author. I also tried to move the description of myself which works on ontoworld to my page here but it did not work.

I also struggle with the grammar, how many square brackets and colons are needed, when a vertical bar and when not, and so on. Hence the large number of minor edits to my name yesterday. Sorry. --Fletchjp 14:21, 5 January 2008 (CET)
 * No need to be sorry! Yes, it's a disadvantage of Semantic MediaWiki that it lacks uniform ontologies. The property names on Ontoworld have grown over time, and while I chose to copy most of them when I set up this wiki, I got others wrong or named them differently deliberately – I don't remember in this case.

And take your time to learn the syntax, using the help pages of this wiki and of Semantic MediaWiki. It's not that much, actually, and if you should really mess up something, it's always easy to revert to an older version of a page. Thanks for your contributions! --Christoph 16:24, 5 January 2008 (CET)
 * It occurred to me afterwards that the thing which did not copy over was in curly brackets and may be a template, which is I guess defined locally. What I did find very helpful here is the page with examples of mathematical markup. --Fletchjp 17:00, 5 January 2008 (CET)
 * Thanks! – Indeed, I just recreated a few of Ontoworld's templates here. However, feel free to contribute templates. If you edit a page using templates on Ontoworld, you should see these templates listed below the editing box. Then you can go to the wiki pages containing these templates (they're in the "Templates" namespace) and create copies of them here. --Christoph 17:04, 5 January 2008 (CET)
 * It works. I have the Template for person working here, although not all of its subattributes. See the example on my homepage. I adjusted the background colour of the top row as it was took dark to read the text. --Fletchjp 17:28, 5 January 2008 (CET)

Classics In Mathematical Thought
JA: I have been thinking for a while now that it might be interesting to try and "semantify" classic works from the history of mathematics and logic, perhaps under the rubric of sample texts. What do you think? Jon Awbrey 19:32, 5 January 2008 (CET)

CL: Jon (Awbrey), I think it's a good idea to try that in this wiki. —Christoph 22:22, 6 January 2008 (CET)

JF: I have access to some books which could be examples for this. I would like to see someone else contribute an example which I can copy. --Fletchjp 15:55, 7 January 2008 (CET)

JA: For my part, I have been interested in seminal texts by Galois, Boole, Peirce, Frege, and Lie. For example, I have been spending some time explicating Peirce's 1870 memoir on the "Logic of Relatives". Jon Awbrey 17:16, 7 January 2008 (CET)

Indexing mathematics on other wikis
I am not sure if this fits in directly, but I was thinking about all the pages of information in existing wikis, such as WikiWikiWeb itself which has approaching 33,000 pages accumulated over a long period, many of which are in categories, e.g. mathematics, semantic web, etc. What I did recently was to try out a program called  DC-dot which will extract Dublin Core information from a web page. There is an example of the generated code which includes a lot of information under dc:subject. One way of using this would be to build up an index of the wiki on a Semantic Wiki without copying over the data, and therefore not violating any copyright. There would have to be mechanism for checking if the pages were updated, which would be difficult if the RDF had to be edited by hand. —Fletchjp 21:20, 6 January 2008 (CET)


 * John (Fletcher), I think it would fit in here. Remember my reaction to Jon contributing some of his works to the MathWeb wiki, which we have already tagged as "sample documents", as they are semantically annotated mathematical documents. John, for semantic annotations like DC metadata extracted from arbitrary wiki pages, I'd rather recommend you to contribute them to Ontoworld. Ontoworld is a wiki about semantic wikis and semantic web in general, while the scope of MathWeb is restricted to mathematical knowledge management (MKM). Sure, I have added lots of pages about semantic web here, but that's just because I'm using semantic web technologies to manage mathematical knowledge. Thus, I'd conclude: If your DC metadata are related to mathematics, they're most welcome here. Otherwise, they might better fit into Ontoworld. —Christoph 22:22, 6 January 2008 (CET)


 * O.K. There is a CategoryMath on the wiki with about 200 links and I will have a look at that. How do I import RDF into here? —Fletchjp 23:35, 6 January 2008 (CET)


 * By way of example IndexOfCategoryMathOnWiki —Fletchjp 23:43, 6 January 2008 (CET)

Page deletion
Can I delete pages on this wiki? On ontoworld I flagged a page as category delete and someone else did it. Here I have used the same procedure on the page John Fletcher (amalgamated with my user page) but the category link is red. What is the procedure here? Thanks --Fletchjp 09:43, 8 January 2008 (CET)

Problem Uploading Image Files
I am trying to upgrade the graphics on some of my articles, but I keep getting a message that says "Internal error &mdash; The upload directory (public) is not writable by the webserver." Jon Awbrey 03:14, 27 April 2010 (UTC)


 * I hope I've now fixed it on the server. Sorry that it took me some days.  Can you please try again? --Christoph 09:25, 4 May 2010 (UTC)


 * Thanks! It seems to be working now &mdash; I'll get the rest of them tomorrow. Jon Awbrey 06:08, 5 May 2010 (UTC)
