Description Andre Engels 2005-04-13 15:38:03 UTC
Could it be made possible (perhaps as part of the database changes for 1.5?) to
show interwiki-links TO a page? And even more important: Could it be shown for
images on WikiCommons which wikis are using that image?
Comment 1 Christian Richardt [Richie] 2005-04-15 08:39:50 UTC
This sounds similar to Bug #1394, although being more general. Could these Bugs/Requests for features be merged 
or mor clearly separated? It's not exactly a duplicate.
Comment 2 Andre Engels 2005-04-15 09:38:39 UTC
Hmmm, yes, they are rather similar. The main similarity is in what is needed for
them - both need something to search all databases rather than just one,
although this one would need a special field for interwiki-links too. Once those
have been implemented (which might be hard, I suppose, to do in a not-too-slow
manner), both can easily be implemented.
Comment 3 Jamie Hari 2007-07-13 04:38:47 UTC
I'd say you might need a few fields, or maybe even its own table would be best.
Having a separate table would make for a cleaner implementation and you could have a whack of indices to speed queries along nicely.

I think images and articles could be both served by this table...

How has MW changed since April '05, that would help or hinder the resolution of this bug?
Comment 4 Rob Church 2007-07-13 04:56:25 UTC
There are some recent musings related to this (well, more bug 10237, but still relevant) at
Comment 5 Roan Kattouw 2009-04-07 18:16:19 UTC
Adding "whatlinkshere" to summary for better searching.

Comment 7 Krinkle 2010-10-22 08:24:41 UTC
The Commons part has been solved by GlobalUsage.

However a global "WhatLinksHere" to see incoming links from all wikis, doesn't exist yet.
Perhaps a similar thing called GlobalLinks ?
Comment 8 Sumana Harihareswara 2012-02-12 12:49:36 UTC
Jan Ainali suggested:

Global Link Search:

A tool that does what Special:LinkSearch does, but on all projects and languages.

Need to have:
Total number of links.

Nice to have:
Total number of links per project in one table.
Total number of links per language in one table.
Total number of links per project and language in one table.
From the last table, links to each "local" Special:Linksearch.
All links in one table order by number of occurencies descending.
Languages/projects with no links could be left out of the tablee instead of showing "0".
Comment 9 Jan Ainali 2012-02-12 21:40:57 UTC
My suggestion is related, but I was mostly curious about external links i.e. showing links to a specific external website. But perhaps, if done in a general way, that wish could be solved by this issue.
Comment 10 Bawolff (Brian Wolff) 2012-02-12 21:46:44 UTC
Note, there is now interwiki stuff in the api:

All links to wikibooks using b prefix:

All interwikis on main page:

There's not really any special page web interface to this though that i am aware of...

Of course doing this in a cross wiki fashion (anything that links to this specific page from any other wiki) is much harder.
Comment 11 Sumana Harihareswara 2012-07-17 13:05:33 UTC
Jan, did you say that you were able to talk with Timo about this a few days ago? What was the result?

We did talk, and there is a tool on the toolserver for that. But :

... that is about external links, this bug is about interwiki links
( vs. [[x:foo]])
Comment 14 Jan Ainali 2012-07-20 07:20:42 UTC
To keep these issues separated, I started for the Global LinkSearch.
Comment 15 Krinkle 2014-06-06 23:47:43 UTC
Of course, before we have a cross-wiki one. We should first have a local wiki one.

See bug 66293.
