== Problem DOI ==

This DOI doesn't work in the template.  I tried several character encodings.  It's in [[Sea_level_rise#References]]. ([[User:SEWilco|SEWilco]] 03:01, 22 May 2005 (UTC))
: 10.1175/1520-0442(2002)015<0487:SOCASI>2.0.CO;2

This solution seems to work:

<nowiki>{{doi|<nowiki>10.1175/1520-0442(2002)015<0487:SOCASI>2.0.CO;2</nowiki>}}</nowiki>

The above is generated by:

<nowiki>{{doi|&lt;nowiki>10.1175/1520-0442(2002)015<0487:SOCASI>2.0.CO;2&lt;/nowiki>}}</nowiki> 

It may be a problem if the doi contains the string &lt;/nowiki>... [[User:Paolo Liberatore|Paolo Liberatore]]&nbsp;([[User talk:Paolo Liberatore|Talk]]) 20:45, 29 November 2005 (UTC)

:A DOI that is made specifically so that it doesn't work on wikipedia. That would be a sight! [[User:Ansell|Ansell]] 03:32, 8 April 2006 (UTC)
::Numerous DOIs using the <nowiki><,>,[ and ]</nowiki> characters will notwork on these templates.I am not sure how to force them to display properly. Numericla entities do not appear to work. See also [[User:Circeus/Maple]] for two other examples. [[User:Circeus|Circeus]] 14:48, 25 July 2006 (UTC)
::My problematic DOIs are ''10.2179/0008-7475(2004)069<0230:SN>2.0.CO;2'' and ''10.1656/1092-6194(2005)012[0023:SASEOA]2.0.CO;2'' [[User:Circeus|Circeus]] 14:55, 25 July 2006 (UTC)

It appears to be a MediaWiki bug, in that the character entity (which would be the correct way to do it) is terminating the link:

{{doi|10.1175/1520-0442(2002)015&lt;0487:SOCASI&gt;2.0.CO;2}}

Using a URL escape works; however, since the same template parameter is also used for the display text, it does not display correctly:

{{doi|10.1175/1520-0442(2002)015%3C0487:SOCASI%3E2.0.CO;2}}

== URL encoding ==

Is there a good reason why you have two separate parameters instead of just using <code><nowiki>http://dx.doi.org/{{urlencode:{{{1}}}}}</nowiki></code>? — [[User:Omegatron|Omegatron]] 02:19, 18 February 2007 (UTC)

:I think I tried and failed to get anything out of {{urlencode}}. Besides, by now, we risk breaking too many uses of the template without real benefits.[[User:Circeus|Circeus]] 22:48, 19 February 2007 (UTC)

== Caps ==

Can we have the output of the template be "DOI:" instead of "doi:" ? This is to bring this template in line with the {{tl|cite journal}} output. --[[User:Rifleman 82|Rifleman 82]] 04:26, 22 October 2007 (UTC)
:This is not good. DOIs should generally be treated as URIs and URIs should spell the "protocol"-part in lowercase (e.g. http: ftp: hdl: doi: urn:). This was discussed on German wikipedia, too and the spelling was changed to lowercase. I am member of one of the non-crossref DOI-supplying organizations (http://www.std-doi.de) and we try to propse the URI notation of DOIs. Almost all publishers use doi:, examples from our field are: {{doi|10.1594/PANGAEA.55366}}, {{doi|10.1016/S0037-0738(99)00071-8}}.

With the new #urlencode parserfunction, there's now no need for the label parameter.

Please replace the contents of this page with those of [[Template:doi/editprotected]].

==Parenthesis?==
The following DOI contains parentheses, and seems to fail to link properly:

{{doi | 10.1016/S0140-6736(98)05145-9  }}

(The link is there, but it the text of the DOI isn't linked.)  
Where is the problem here? 13:20, 14 May 2008 (UTC)

I have the same problem with {{doi|10.1016/S0168-0072(99)00032-9}}, apparently all Elsevier DOIs are affected. I notice that deleting the slash also makes the problem disappear, so it is not necessarily related just to the parentheses. URL encoding does not help, and in fact, breaks the link: {{doi|10.1016%2FS0168-0072%2899%2900032-9}}. Character entities do not help either: {{doi|10.1016&#47;S0168-0072&#40;99&#41;00032-9}}.

IIRC, the offending doi displayed OK two weaks ago, I thus strongly suspect that the bug is caused by one of the recent changes to the template. Can someone revert it to the working March 26 version, and properly debug it before making further sweeping changes? — [[User:EJ|EJ]] ([[User talk:EJ|talk]]) 15:59, 14 May 2008 (UTC)
:I have reverted. The reason id/label was implemented was that, for some reason, the #urlencode simply ''did not work'' (I think there's a bug filed for it, actually). Hence the new form made the link practically invisible. [[User:Circeus|Circeus]] ([[User talk:Circeus|talk]]) 21:45, 10 June 2008 (UTC)

== Parameter “label” ==
I don't understand what the parameter “label” is good for. The version without this parameter produces exactly the same link as the one with the parameter:

 | id = 10.1175/1520-0442(2002)015%3C0487:SOCASI%3E2.0.CO;2

}}</nowiki>

}}</nowiki>

Special characters (see [http://en.wikipedia.org/w/index.php?title=Template:Doi/doc&oldid=211310413 old version of doc]) have to be replaced in the parameter “id” anyway. --[[User:Leyo|Leyo]] 22:11, 10 June 2008 (UTC)

:At some points, it appears that the way urls are handled was changed at they now allow unescaped carets (I was not aware of this), which was not possible back in December/January.

== Suggested simplification ==

{{collapse top |title=OP is a globally-blocked sock.}}

A doi has two functions, right? (1) As an identifier, and (2) as a (more or less) stable link to a web page. I would question the sense of actually displaying the identifier in WP articles, as seeing the identifier has rather few uses that I can see, but it adds considerably to complexity and clutter, thereby distracting from what is really important. It is somewhat like using pi, in the sense that you can use pi in a calculation without needing to see the actual approximation being used. So, why not display doi links just as the term doi, without displaying the identifier bit? If someone really did want to see what the identifier actually is, for some reason, then they still have 3 easy options:
(1) Go into edit mode to see the doi link in full; or
(2) Use the 'Copy link address' facility on their browser; or
(3) Click on the doi link and see the full identifier on the linked web page.
Generally speaking, I would suggest that articles with lots of unnecessary identifiers showing is a bad idea.

::: @Headbomb Actually, no, the 'copy link address' facility on browsers would work fine. The only thing is that you wouldn't be able to copy the reference citation and the doi in one go.

::I am not sure anything can be done about this but it should probably be noted that this also fails with interwikilinks, e.g.: [[doi:10.1126/science. 1140516]] renders the link with an underscore instead of a space. —[[User:Uzume|Uzume]] ([[User talk:Uzume|talk]]) 01:45, 7 December 2021 (UTC)

::::The example doi in this discussion was once a working identifier (with the space); it still works to some extent because you don't get the doi.org error page but rather you get a 404 error at science.org.  I expect that that doi has been replaced with something else.  Regardless, it is doubtful that the interwikilink form (<code><nowiki>[[doi:10.1126/science. 1140516]]</nowiki></code>) can ever be made to work because MediaWiki treats interwikilinks like any regular wikilink: urls are created from the wikilink syntax such that spaces (even when percent encoded) are replaced with underscores.  And why is <code>doi:</code> an interwiki prefix anyway?  The template works because it does not replace spaces with underscores.  I suppose one might wander over to phabricator and propose that if non-mediawiki sites can be interwikilinked, the 'interwiki' urls created should not use underscores for spaces in the url.

== doi-access=free ==

I have hacked the sandbox to use {{tlx|catalog lookup link}} so that the doi identifier can be marked as free-to-read in the same way that a free-to-read doi in a cs1|2 template can be marked: {{para|doi-access|free}}.  The [[Template:doi/testcases]] failures are not really failures.  The live version of this template does not trim whitespace from the doi so the leading whitespace in <code><nowiki>{{{1}}}</nowiki></code> (test 2) appears in the final rendering but {{tld|catalog lookup link}} does trim whitespace so the whitespace is not rendered.

The sandbox version of this template supports the cs1|2 <code>free</code> access indicator which is accomplished by template styles so the sandbox rendering includes the necessary template styles stripmarker:
:<code><nowiki>{{doi/sandbox|10.5194/essd-12-2013-2020}}</nowiki></code>
::{{code|{{doi/sandbox|10.5194/essd-12-2013-2020}}}}
:::{{doi/sandbox|10.5194/essd-12-2013-2020}}
{{small|I may tweak {{tld|catalog lookup link}} to suppress the template styles when an access icon is not required...}}

Using {{para|doi-access|free}} (no other value supported):
:<code><nowiki>{{doi/sandbox|10.5194/essd-12-2013-2020|doi-access=free}}</nowiki></code>
::{{code|{{doi/sandbox|10.5194/essd-12-2013-2020|doi-access=free}}}}
:::{{doi/sandbox|10.5194/essd-12-2013-2020|doi-access=free}}

Without objection, I shall update the live template.

:::I have hacked a module in [[Module:Sandbox/trappist_the_monk/doi|my sandbox]] that has a copy of the doi validation code from [[Module:Citation/CS1/Identifiers]].  The new module uses [[Module:Citation/CS1/Utilities]], [[Module:Citation/CS1/Configuration]], and [[Module:Citation/CS1/styles.css]].  The result is a close mimic of cs1|2 doi renderings.  The new module supports {{para|doi-access}} and accept-as-written markup.

== id as alias for unnamed first parameter ==

{{Edit request|level=template|answered=yes}}
I have edited [[Template:doi/sandbox]] to remove id as an alias for the unnamed first parameter. The template currently displays correctly when given the {{para|id}} parameter instead of an unnamed first parameter, but still places the page in [[:Category:Pages with DOI errors]]. That category does not currently have any items in it using {{para|id}}. After this edit is made, pages will still be placed in that maintenance category, but will not display as expected.
