Wikimedia / Wikipedua Development Fruits

Chris Thomas — 2013-05-22T15:37:23

Hey, just wanted to share the fruits of some Mediawiki API work....

www.mapedia-uk.net

Try doing a search in the Historical types, such as British Prehistory or Roman Britain. Search for these in the UK and the locations you'll find there are Wikipedia articles that feature locations.

Still a WIP, with some teething problems in our system. But.. It does work :)

any feedback welcome,

Cheers

Does anybody know what the meaning of rctype="external" in recent change list is

Liu Chenheng — 2013-05-15T02:47:51

Hi, All,
Does anybody know what the meaning of rctype="external" in recent change
list is. I saw a lot of this type of changes.

Thanks.

Checking whether Real Name is enabled or not in aMediaWiki site

Adrián Chaves Fernández — 2013-05-10T06:38:04

Is it possible to check through the MediaWiki API (or another non-interactive way) whether real names are enabled or not (http://www.mediawiki.org/wiki/Manual:$wgHiddenPrefs) in a MediaWiki site?

Total number of pages in a namespace?

Chux — 2013-05-08T01:33:55

Hi,

I was wondering if there is a way to know how many pages are inside a
namespace, for example how many pages are "Categories", or how many pages
are "Articles"?

Thanks,
Chux

Filtering protected templates when listingtemplates associated to a page

Chux — 2013-05-03T06:04:33

Hi guys,

I am trying to retrieve the templates associated to a page:
http://en.wikipedia.org/w/api.php?action=query&prop=templates&format=json&tllimit=500&pageids=199445

So in this scenario, I am able to get a list, but I noticed some of the
listed templates here are marked as protected. I am not able to see any
attribute in the results that shows this flag.

Any ideas on how can I filter those out?

Thanks,
Chux

[Mediawiki-api-announce] Echo breaksmeta=userinfo&uiprop=hasmsg

Brad Jorsch — 2013-05-03T00:09:07

If your bot checks meta=userinfo&uiprop=hasmsg to determine if a talk
page message has been posted in order to stop running, it is currently
broken since Echo disables that along with the orange bar.

styling and css or "neater" json? api?

Luigi Assom — 2013-04-28T22:44:00

Hi all!

I've been studing the api and had a look to the extensions, I have some
questions about the proper way to style the html obtained of an article.

I am looking at the parse api.
I wonder if contentformat or contentmodel do the trick to obtain an article
with a "cleaner" html or the matched css, so that it can be "re-styled".
Unfortunately, I have not been able to use this parameters:
http://en.wikipedia.org/w/api.php?action=parse&page=New%20Jersey&contentformat=text&contentmodel=css

Could you please give me an example so that i understand what do they do?

Alternatively, i could use mobileformat parameters, which seems to get an
adapted and cleaner html.
But still, I would need to find out the scheme of Id and classes used in
the html to re-style it.

Where could I find such scheme?

I also would like to get rid of the [edit] or [update] elements: I want the
article in "read mode" only.

Is there maybe a parameters providing this output?

If someone of you ever saw the "Dictionary" application in a

first image of articles, sequential request

Luigi Assom — 2013-04-27T19:48:25

Hello,
I read there is no api to obtain main article of wikipedia articles, but I
also noticed many topics on stackoverflow are old of one year.

Is there any progress on this?
Also, is it possible to obtain thumbnails of images (or specified size) for
multiple pages?

If there is no way to obtain the first image appearing in the article,
which way would you suggest in order to pick up the image from a set of
images in the page, avoiding to parse the whole page and get the thumbnail?
this would be important because I am trying to make a sequential call and i
don't want to query in parallel.

Thank you for sharing ideas and state of the art!
Luigi

Parser Cache

Chris Thomas — 2013-04-27T13:12:26

Hi, I am requesting a number of pages to be parsed on Wikipedia. Generally I
am being returned the text, as expected. For some higher traffic pages, I am
instead receiving a notice about it being cached. Could someone give me some
pointers as to how I am meant to handle this? I’m guessing I need to make a
new request to the parser, cache, using the provided key (see below). Does
anyone have a link to a page, that explains this behaviour? Notice text is
below…



Cheers

[Mediawiki-api-announce] BREAKING CHANGE: Wikidata langlinks handling in action=parse, list=allpages, list=langbacklinks, prop=langlinks

Brad Jorsch — 2013-04-25T18:24:20

Language links added by Wikidata are currently stored in the parser
cache and in the langlinks table in the database, which means they
work the same as in-page langlinks but also that the page must be
reparsed if these wikidata langlinks change. The Wikidata team has
proposed to remove the necessity for the page reparse, at the cost of
changing the behavior of the API with regard to langlinks.

Gerrit change 59997[1] (still in review) will make the following
behavioral changes:
* action=parse will return only the in-page langlinks by default.
Inclusion of Wikidata langlinks may be requested using a new
parameter.
* list=allpages with apfilterlanglinks will only consider in-page langlinks.
* list=langbacklinks will only consider in-page langlinks.
* prop=langlinks will only list in-page langlinks.

Gerrit change 60034[2] (still in review) will make the following
behavioral changes:
* prop=langlinks will have a new parameter to request inclusion of the
Wikidata langlinks in the result.

A future change, not co

API change request

Liu Chenheng — 2013-04-23T05:46:29

Hello, All.

I have a request here:
I listen to the recent change list, and to the "page restore" action, I
receive the log like this:

<rc type="log" ns="0" title="William Pierce, Jr." rcid="565524106"
 pageid="38932317" revid="0" old_revid="0" user="Secret" oldlen="0"
newlen="0" timestamp="2013-03-27T04:02:12Z" comment="5 revisions restored:
keep the original redirect" logid="48107996" logtype="delete"
logaction="restore"/>

It's said that it restores 5 revisions but not tells me what are the 5
revisions.

But in the log of "revision restore/delete", we can get the list of the
affected revisions.

Is it possible to do some changes of the API in order to support this
feature.

Thanks.

Using the API on WikiData ?

Nicolas Vervelle — 2013-04-16T08:36:25

Hi,

Is it possible to use the API on WikiData, for example to remove or update
some interwiki links ?
How do you do that ?

I'd like to create a few bot tools for deleting / renaming categories, and
I'd need to update the interwiki on WikiData ?

Thanks
Nico

A question about restore and delete page

Liu Chenheng — 2013-04-15T09:21:43

Hello!

I have a problem here:
Do the restore and delete page action can cancel out each other?
i.e. delete a page and then restore this page, equals we do nothing of this
page.

I listened the recent changes, and got more than 5 revisions of this page:
http://en.wikipedia.org/w/index.php?title=William_Pierce,_Jr.&redirect=no

And then I got a delete page action,
later I got a restore page action, as you can see from the log:
<rc type="log" ns="0" title="William Pierce, Jr." rcid="565524106" pageid="
38932317" revid="0" old_revid="0" user="Secret" oldlen="0"newlen="0"
timestamp="2013-03-27T04:02:12Z" comment="5 revisions restored: keep the
original redirect" logid="48107996" logtype="delete"logaction="restore"/>

it only restored 5 revisions but not specified what the 5 revisions were.

In my opinion, the restore and delete page actions should cancel out each
other like the restore and delete revision actions.

[Mediawiki-api-announce] Non-functional xmldoublequote parameter to format=xml being removed in 1.22wmf2

Brad Jorsch — 2013-04-10T01:25:56

It was recently noticed[1] that the xmldoublequote parameter to
format=xml has been broken since r55641,[2] merged in August 2009 and
released with MediaWiki 1.16. Since it has been broken for over 3.5
years, it was decided to just remove the parameter.[3]

Background: The xmldoublequote parameter was added in response to bug
11401,[4] as a workaround for the fact that XPath 1.0 did not specify
any mechanism for escaping quotes in string literals. It caused all
attribute values and text content to be double-encoded, e.g. a double
quote would be represented as &amp;quot;, and an ampersand would be
represented as &amp;amp;.

Workaround: XPath 2.0, released in 2007, does include a quoting
mechanism. Clients using XPath 1.0 may use string concatenation as a
workaround.[5]

Problem with generating email tokens

Prabhavathi Matta — 2013-04-08T06:20:34

Hi,

I am working on an UC Berkeley research project to analyze wikipedia users'
behaviour. As a part of the project, I am developing an application which
sends a survey to a random sample of recent users. I am using mwclient code
to send emails though API. After testing around 3-4 times, the email tokens
are not getting generated anymore. I tried to send mails from different
login user. It still gives the same error.

When I tried to send email from website
http://en.wikipedia.org/wiki/Special:EmailUser. It says," As an anti-spam
measure, you are limited from performing this action too many times in a
short space of time, and you have exceeded this limit. Please try again in
a few minutes." It has been 8 hours since and I still get the same message.

Does this mean, I exceeded limit for my  ip address or for that user? When
I googled it, the rate limit seems to be about 1000 api calls. I have sent
mails only to 3-4 test users for 5 times maximum.

Which is a better way of sending emails to wikipedia users -

About continuation of RecentChanges

Liu Chenheng — 2013-04-02T10:30:07

I used the new style to request recent changes, i.e.

http://en.wikipedia.org/w/api.php?action=query&list=recentchanges&continue=

and then I simply copied the information <continue continue="-||"
rccontinue="2013-04-02T10:26:26Z|567310672" />

to request the prev changes:

http://en.wikipedia.org/w/api.php?action=query&list=recentchanges&continue=
-||&rccontinue=2013-04-02T10:26:26Z|567310672

However, the results returned to me were not the correct rcid from 567310672

Is there anything wrong?

Thanks.

Article Lat Long

Chris Thomas — 2013-03-25T12:30:12

Hi, we would like to place Wikipedia locations on an interactive map, with
the Article associated with it. Hopefully this will create an Map centric
display of Wikipedia historical locations (rather than a text/page centric
one.). Don't worry, full credit and links will be given.

 

So. Is there a reliable way, using the API to gather the Co-ords of
locations (that have them)? Ideally, we would like to have a pair of queries
that.

 

.         Returns = Articles of a category, that ALSO have a location Co-ord
specified

.         Returns = The article, or some kind of data block with that
Co-ord, based on the articles Title

 

I have watched the video tutorial, and dabbled with various Queries and
Parses of pages. I can get a list of Articles that match a given Category,
and I can compile a list of Categories. However, I am finding the
geolocation data to be somewhat patchy. But that's probably down to me not
knowing the magic formula. 

 

So, does anyone know how to address this issue? Any help most app

[Mediawiki-api-announce] Reminder on continuation("breaking"changes coming soon)

Brad Jorsch — 2013-03-22T00:03:02

Remember that clients should not be depending on the specific query string
data returned inside the query-continue node, with either the old-style or
new style continuation.

As a partial fix for bug 24782[1], Gerrit change 22742 will cause
action=query&list=recentchanges to start returning rccontinue for
continuations rather than rcstart as it has done in the past. Changes of
this type may be coming to other modules as well as further fixes to bug
24782 are implemented.

'Protect' protects a page to all wiki's participants (without take into account the 'protect group')

Pericles Sobreira — 2013-03-19T17:15:27

Hi all.

When I protect a certain page (action=protect&protections=edit=G8), all
users of the wiki are blocked to edit it (as expected), but also, the
participants of G8 (the group that should edit this page)... someone knows
this issue?

I initially created the following two lines in LocalSettings.php:
$wgGroupPermissions['G8']['edit'] = false;
$wgGroupPermissions['G8']['read'] = false;

And after, I changed these permissions to 'true':
$wgGroupPermissions['G8']['edit'] = true;
$wgGroupPermissions['G8']['read'] = true;

I have also modified the following line in the DefaultSettings.php file:
$wgRestrictionLevels = array( '', 'autoconfirmed',
'sysop','G1','G2','G3','G4','G5','G6','G7','G8');

But, nothing...
Does anyone know if there is something to configure/do yet?

Thanks for your help.

Provisional API extension for CAPTCHA onaction=createaccount

Brion Vibber — 2013-03-14T19:55:16

As some folks may recall, an action=createaccount was added to the API a
few weeks ago. Unfortunately the first pass didn't include CAPTCHA support,
so we haven't been able to use it for the live sites yet (which use
ConfirmEdit's "FancyCaptcha" mode). We expect to start using this in the
next couple weeks for the mobile Commons apps, so it's time to make it
captcha-friendly...

I've made a first stab at adding support, based on the existing captcha
interfaces for login and editing:

MediaWiki core: https://gerrit.wikimedia.org/r/53793
ConfirmEdit ext: https://gerrit.wikimedia.org/r/53794

So far I've tested it with the default 'math captcha' mode, with this test
rig: https://github.com/brion/mw-createaccount-test


If a captcha needs to be run, action=createaccount will spit back a result
including a 'captcha' field including several subfields, such as in this
example:
https://www.mediawiki.org/wiki/API_talk:Account_creation#Captcha_additions

Since account creation requires a first request to get a token a
