semantic-mediawiki.org's Introduction

Semantic MediaWiki

Semantic MediaWiki (a.k.a. SMW) is a free, open-source extension to MediaWiki – the wiki software that powers Wikipedia – that lets you store and query data within the wiki's pages.

Semantic MediaWiki is also a full-fledged framework, in conjunction with many spinoff extensions, that can turn a wiki into a powerful and flexible knowledge management system. All data created within SMW can easily be published via the Semantic Web, allowing other systems to use this data seamlessly.

For a better understanding of how Semantic MediaWiki works, have a look at deployed in 5 min and the Sesame, Fuseki triplestore video, or browse the wiki for a more comprehensive introduction.

Requirements

Semantic MediaWiki requires MediaWiki and its dependencies, such as PHP.

Supported MediaWiki, PHP and database versions depend on the version of Semantic MediaWiki. See the compatibility matrix for details.

Installation

The recommended way to install Semantic MediaWiki is by using Composer. See the detailed installation guide as well as the information on compatibility.

Documentation

Most of the documentation can be found on the Semantic MediaWiki wiki. A small core of documentation also comes bundled with the software itself. This documentation is minimalistic and less explanatory than what can be found on the SMW wiki. It is however always kept up to date, and applies to the version of the code it comes bundled with. The most important files are linked below.

Support

Primary support channels:

User mailing list - for user questions
SMW chat room - for questions and developer discussions
Issue tracker - for bug reports

Contributing

Many people have contributed to SMW. A list of people who have made contributions in the past can be found here or on the wiki for Semantic MediaWiki. The overview on how to contribute provides information on the different ways available to do so.

If you want to contribute work to the project please subscribe to the developers mailing list and have a look at the contribution guidelines.

Tests

This extension provides unit and integration tests and are normally run by a continuous integration platform but can also be executed locally using the shortcut command composer phpunit from the extension base directory. A more comprehensive introduction can be found under the test section.

License

GNU General Public License, version 2 or later. The COPYING file explains SMW's copyright and license.

semantic-mediawiki.org's Issues

Set up pretty URIResolver

Set up Google Maps API

Starting June 11, 2018 every site needs an Google Maps API key. At the same time it starts be be a paid service for everyone with a 200 USD credit for free calls every month.

Applicable for "s-mw.o" are dynamic maps with up to 28,000 loads. So we will go with that. I the limit of 28,000 is reached no Google maps will be served on the wiki.

Finding the console for API-keys is horrible. This is the quick link.

Docu I found along the way:

s-mw.o

Obtain Google Maps API key
Add the key to configuration
Switch to "leaflet" as default mapping service in configuration
Add a note to all pages providing Google Maps docu referencing this issue

The API may only be used from https://www.semantic-mediawiki.org or https://semantic-mediawiki.org. Moreover only the "Geocoding API" and the "Maps JavaScript API" may be used.

sb.s-mw.o

Obtain Google Maps API key
Add the key to configuration
Switch to "leaflet" as default mapping service in configuration
Add a note to all pages providing Google Maps docu referencing this issue

The API may only be used from https://sandbox.semantic-mediawiki.org. Moreover only the "Geocoding API" and the "Maps JavaScript API" may be used.

Note: In April 2018 sb.s-mw.o had 687 calls to the "Geocoding API" and 10 calls to the "Maps JavaScript API". No other specialized APIs were called.

Unable to read pages

For example https://www.semantic-mediawiki.org/wiki/Help:User_manual?uselang=en gives

You do not have permission to read this page, for the following reason:

You must confirm your email address before editing pages. Please set and validate your email address through your user preferences.

This applies to all pages.

Namespaces in Spanish

Hi,
There is some talk pages of the "Help" namespace translated erroneously, "talk" is translated by "habla sobre". I checked if this is happening by a template or a magic word used to change the display title, but I didn't found nothing related. Aftter, I think it could be related with the configuration of the namespaces or something else, but I change my system language and then enter in a private tab to check it, but in both the display title is "habla sobre

The strange is that it happens with some talk pages, because there . I listed two help talk pages in which I found this error:

Selecting pages
Special property Subproperty of
Then I found this help talk page in which the display title is "Discuss...":
Special property "Equivalent URI"
And then, the help talk pages no created yet have "Help talk", like this one:
Special property Has processing error

Now I have not time to search more pages in with happens this. What happens is a bit confusing. Any idea about it?

Regards,
Iván

Implement "mod_reqtimeout"

Thus it will be possible to serve a custom error page in case there is too much load on the server. See comment on issue 1687

Create DMARC TXT record for semantic-mediawiki.org

Reported here. Some e-mail providers reject e-mails coming from domains without a DMARC policy. So we probably have to cater for this bogus.

Update wiki to MW 1.27 LTS branch

This should be done after the release of SMW 2.4.0

Current blocker is T137843 for the ConfirmAccount extension.

JavaScript of the info box for result formats failing

Most probably since the update to MW 1.27.x the respective script "tab/panel right slide" fails, at least on recent Fx and Ch:

/**
 * Tab/Panel right slide
 * @author mwjames
 */

$("#panel-tab").click( function (event) {
	event.stopPropagation();
	showIfNotVisible( "#panel-content" );
} );

function showIfNotVisible( element ) {
	var width = $( '#panel' ).find( 'table').width() + 8; 
	if ( $(element).css( "width" ) == width + 'px' )
		$(element).animate( { width: 4 }, 1500);
	else
		$(element).animate( { width: width }, 1500);
};

$( function() {
	var element = $("#panel-content"),
	status = element.attr( 'class' ),
	width = element.find( 'table').width() + 8;

	if ( status === 'close' ){
		element
		.width( width )
		.animate( { width: 4 }, 1200);
	} else {
		element
		.width( width );
	}
} );

@mwjames It will be great if you could have a peep at this.

Backup?

Do we have a backup plan? It would be a shame if things like below vanish in thin air due to a missing backup.

Github extension stopped working

The display of content used to work:

Reconfigure Postfix

Upgrade OS

PHP7? - I see that ~~both the main site and~~ the sandbox are still running PHP 5.6. Any ETA on them switching to 7.x?

One reason of why I'm asking is that I'd like to do some work on the GitHub extension and bump it to 7.0+ at the same time.

"Special:ActiveUsers" with database errors

@mwjames Do you have an idea which one may have caused this and provide fluff ... Since Semantic Notification was not touched ...?

Implement "mod_security"

This is a add-on module to Apache which may improve protection against the effects of unwanted traffic by making use of rules that can be applied to carry out specific functions.

See "mod_security"

@kghbln Something is wrong here, all of the sudden in different places all page titles contain "Über Finland diskutieren".

Mailing lists down?!

My release announcement for SemanticMediaWiki/SemanticMediaWiki#2996 did not get through yet and it is no longer possible to subscribe to a mailing list.

Ticket 16426

Error logging totally broken

Apache does no longer log errors or at least no error log file is being created.
PHP does no longer show errors. The following settings do not trigger error reporting:

error_reporting( -1 );
ini_set( 'display_errors', 1 );

$wgShowExceptionDetails = true;
$wgShowSQLErrors = true;
$wgShowDBErrorBacktrace = true

link Page Schemas tutorial from Main_Page

For reasons described here, I wanted to verify functionality now that Page Schemas has been installed on the sandbox. (Thanks, KGH!) I was able to work through an example, which I subsequently documented as a tutorial for creating datastructures from Page Schemas. I believe this tutorial may be useful to OP; YMMV, but if you agree, please link it into the sandbox main page, in (e.g.) section=Extension related examples. (I'm not seeing UI to do that, so am assuming I lack permissions.)

REM: $wgPingback

User manual, translations, and more ...

A well maintained user documentation is vital to explain on what Semantic MediaWiki is, it can do, and it cannot do but in recent years the translated documentation has been greatly diverted from what is available in English. To avoid widening the discrepancy, I hope that following changes to the user manual in general and preparation towards using the Translate extension will improve the situation now and in future.

The navigation is no longer (and hereby its contents) tied to some fixed text and instead uses annotations and the tree format to generate an appropriate (in terms of the annotated language) table of contents.
Language detection and annotation is done by SIL
To improve the situation with the docinfo template, the Help:User manual page show cases the "new" doc.info replacement. The "old" docinfo template is convoluted and contains value annotations that seems hardly in use. Furthermore, document specific annotations have been moved into a subobject to isolate document management specific annotations.
Also, content that seems beyond repair should be move into the Archive namespace to avoid contradictory assumptions about SMW functionality.

PS: I would have expected that in 2017, MediaWiki is sufficiently prepared to display content in different languages but unfortunately that is not the case as demonstrated in [0].

Composer 1.6.4 obviously broken

The aforementioned version of Composer is broken since it silently uninstalls apparently arbitrary software which is defined in "composer.local.json". Since WMF merge-plugin was not changed since January I believe that this may be ruled out as a cause.

On s-mw.o it uninstalled chameleon, on sb.s-mw.o it unistalled SRF and Mermaid. In the latter case this happened during a manually triggered composer update run without any prompt about the uninstall.

I have disabled the cronjobs for updating via composer for s-mw.o and d.s-mw.o for now.

Category update?

Category update (or the lack of it) has been widely discussed [0] with [[Category:External identifier example]] [1] and [[Category:Sample_pages]] missing members.

Special:Ask [2] doesn't rely on MW's category table therefore can be queried and shows which pages are missing from the standard Category page display.

Upgrade to Bionic Beaver (18.04 LTS)

Ubuntu 18.04 LTS was released last week. This is a tracking issue for upgrading the server. Since it serves with PHP 7.2 I will do the upgrade in October 2018 earliest and December 2018 latest, at least that's my plan.

Switch ConfirmEdit to use reCAPTCHA (NoCaptcha) and abandon ConfirmAccount

It actually starts to get on my nerves to create user accounts for users because of ConfirmAccount not playing with MW 1.27 (yet?). I will git ConfirmEdit (NoCaptcha) a shot and see there we go from here.

Consider Hetzner Cloud for hosting

Today Hetzner announced its new clound hosting service: https://cloud.hetzner.com/

Website outage (10 Jan 2017 - 11 Jan 2017) post-mortem

With reference to [0, 1, 2] maybe a quick analysis as to what caused the outage and some suggestions on how to recover more quickly given that several people reported [1, 2] the issue, yet only after 24h the website regained an accessibly state.

[2] has noted:

I guess this is a DOS attack. The VM should be rebooted and see if this makes them back off.

Was it a DOS attack or an internal issue with the software?
In case it was a DOS, was the website vulnerable to a certain type of DOS (some ports remained open etc.)?
Do we know the a reason why the automatic reboot didn't took place (maybe due to some missing configuration)?
In case the situation arises again in future and someone is unable to intervene maybe a redirect to something like [3] should be provided temporarily

Using fixed tables?

Using fixed properties ($sespUseAsFixedTables = 'true';) is recommended in the docs for SESP. In the light of #14, however, I'm wondering if this is fine for SMW 2.4.4.

Main wiki still extremely slow

I wanted to poke a bit at the maps docs, but with this speed I need to wait half a minute before a page loads :(

Github gh-pages for project status overview (idea for pick-up)
