Background[edit]

Magic links are a feature of MediaWiki core that create automatic links for 3 hardcoded external identifiers:

For the purposes of this RfC, we are not considering free external links (e.g. typing just https://www.example.org) to be a magic link.

Problem[edit]

These are hardcoded, inflexible, un-localizable, and generally unexpected. If this feature were proposed today, it would be rejected in favor of using templates or interwiki links. There have been long standing requests to make them disable-able, move them to an extension, or remove them outright.

In many cases, local templates are preferable and more advanced than magic links. For example, on the English Wikipedia, Template:ISBN checks for invalid ISBNs and adds them to a tracking category for editors to fix up.

Proposal[edit]

As of gerrit:309528 it is now possible to disable magic link functionality using $wgEnableMagicLinks. Our eventual goal should be to remove all magic link functionality from MediaWiki core. While moving them to an extension would allow us to remove them from core, it would probably entrench magic links even deeper in the parser as we would need a mechanism and hook system to support an extension to add magic links.

Instead, we should:

  • YesY Done Add a tracking category (via ParserOutput::addTrackingCategory()) to any page that uses a magic link (3 categories, one for each link type)
  • Add a {{ISBN:...}} parser function that replicates the functionality of the magic word (validation and linking to Special:Booksources).
    • It has also been suggested that we could use a "ISBN" virtual namespace that redirects to Special:Booksources
    • Discussion on phab:T148274 is still ongoing.
  • VisualEditor and other editing tools would continue to support ISBN/RFC/PMID "magic" links as they do, but convert it to a proper link client-side.
  • YesY Done RFC and PMID should be added to the Wikimedia interwiki map and the MediaWiki default one if they aren't already.
  • YesY Done In the MediaWiki 1.28 release, default magic links to being disabled. Wikimedia wikis would still have it enabled for now.
  • In progress In progress Encourage users to migrate to using the parser function and interwiki links or local templates (e.g. w:Template:ISBN), probably using bots and other assisted tools.
  • Remove magic link capabilities in MediaWiki 1.30 (1 year later, also LTS).
    • Update: this part was controversial, and will be re-evaluated based on the response to disabling by default.
    • We would retain ParserOptions::getMagicISBNLinks() and co. but they will always return false, in order to signal to extensions that the magic links are disabled.
    • Old revisions would no longer have autolinks, but that should not reduce the readability of the content as they are well known identifiers.
    • Move Special:Booksources and the ISBN parser function to an extension.

Comments[edit]

What for would you do this? It will clutter all the projects with extra template calls and other extraneous crap. Rich Farmbrough 18:03, 27 December 2016 (UTC).

There's concern on enwiki (here, for example) about the loss of the ISBN and PMID magic links. There's also concern about the lack of discussion. The first most of us knew about this was when a bot operator submitted a request to remove the links. Can the disabling of the links be halted so that a wider discussion can be held first?

  • Lets look at one "reason" un-localizable, that issue is just tagged as "won't fix" for "the absence of objections." I would have said that localisation is totally trivial, certainly as easy as localising a set of templates. Rich Farmbrough 23:16, 2 January 2017 (UTC).
Has there been any real discussion on the actual sites? This will have a huge impact. [It seems to me that this change goes against consensus? See Removal of ISBN magic links.] Jeblad (talk) 13:12, 15 April 2017 (UTC)
  • At first I thought this cleanup might be a good idea, then I started to wonder if magic links is just the kind of feature that might solve the currency converter problem. Now we write into articles what a specific currency might be, and how it might be converted to a local currency, but by using magic links for the short three-letter codes we could simply parse out the currency and add a currency converter without cluttering the wikitext. This is not that common, so perhaps it is acceptable to use a parser function in those cases. It would probably not go long before someone have created templates for all currencies, with no real additional functionality, if it is added as a parser function. I would prefer silent parsing of an inline magic link. [Just to be clear; I do not support this RfC.] Jeblad (talk) 13:18, 15 April 2017 (UTC)
  • I think this is a really, really bad idea. It will result in many, many, many future ISBN citings for which editors won't use the template and thus won't be linked anymore. I am strongly opposing this RfC. --Matthiasb (talk) 05:20, 23 May 2017 (UTC)
Please keep the magic links, why increase work load for editors? And why clutter the source text, so that it becomes less readable to the vast majority of non-coders (writing an encyclopedia) and potential new authors? Cheers, --Ghilt (talk) 11:00, 23 May 2017 (UTC)
  • I find the magic links to be useful too. They should not be disabled. I'm even proposing more magic links, e.g. for DOIs and URNs! --Gretarsson (talk) 15:30, 23 May 2017 (UTC)
  • Magic links are useful, templates are geeky. So the more templates, the less attractive the wikiverse will get for non-geeks. So like Matthiasb, Ghilt and Gretarsson. And this has to be discussed on at least 50-70 wiki-projects themself, not only here in some back room of geeks. Grüße vom Sänger ♫(Reden) 15:50, 23 May 2017 (UTC)
  • You propose to disable an extensively used and useful feature without any need, without any existing alternative and (therfore) without any improvement. CONTRA --Fano (talk) 16:03, 23 May 2017 (UTC)
  • I miss any reason for abandoning these widely used features. The claims above under the header "problem" seem ridiculous to me. Un-localizable is patently untrue, as localizing them is as easy as apple-pie. Hardcoded is exactly why they are preferable to templates, they need no user activity. And while they are inflexible, that too is exactly what they are supposed to be. They fulfill one purpose, and do so very well. Unexpected is the most laughable reasoning I have read so far on this wiki. These features have been coded for a reason, they shall and do link three well defined information patterns of utmost importance to well established resources. Some years ago you removed DOI from the magic words, and I still miss it. So my proposal would be to reintroduce DOI as magic word ASAP, and certainly keep the three existing ones. --H-stt (talk) 09:26, 24 May 2017 (UTC)

  • Comment from technical site: It will be very helpful to change the Magics to Templates, because of a better possibility to localize or search those contents by API or as database entry as Table Templatelinks including parsing key and value. The edit on article pages is not very more difficult, but we should use our de:Template:Zitation simply a little more to catch such entries. I only can see a helpful optimization and we should do this. Doc Taxon (talk)
  • The ISBN magic link has been in use several dozen million times, I guess. This RfC is, in comparison, absolutely nothing. I can't take this seriously the way it looks. Man77 (talk) 16:08, 25 May 2017 (UTC)
