Use in an infobox[edit]

Marshall Goldsmith
Born (1949-03-20) March 20, 1949 (age 66)
Valley Station, Kentucky
Alma mater
Occupation
Spouse(s) Dr Lyda Goldsmith
Website
marshallgoldsmith.com

An example of the use of {{Authority control}} in an infobox can be found on Marshall Goldsmith; I reproduce it here (without the photo). For articles with no infobox (yet!), the AC template can still be used in the footer. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:37, 22 August 2012 (UTC)

I suggest that you take steps to make it more integrated into the infobox. In the past there have been discussions which have concluded that all fields in the infobox were equal. See for example WP:INFOBOXFLAG. Would it be possible to have it appear more like Alma mater does in this example? Stuartyeates (talk) 11:09, 22 August 2012 (UTC)
While I would prefer that visual presentation, I'm not sure that it's possible, without either a) making separate AC parameter(s) to each biographical infobox or b) making a separate template for use in infoboxes, while retaining the original template for use outside infoboxes. Anyone else got any thoughts? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:36, 22 August 2012 (UTC)
I've now added the relevant hCard microformat markup to the AC template; when it's used in an infobox, the first-found UID will be emitted as part of the infobox's microformat. For that reason, I've moved VIAF into the first position. Once we decide on a solution, it can also be mapped in DBpedia. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:39, 22 August 2012 (UTC)

Any thoughts on moving this forward? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:37, 25 February 2014 (UTC)

I don't understand what you propose or what is illustrated here. To wit, the authority control module(?) of {{infobox person}} in our biography Marshall Goldsmith displays ISNI: (on two lines, for me), BNF: and (data) links as well as VIAF: and GND: [2 plus the label] that are displayed here in talk space, for me now. I don't know how you have effected that difference technically or what you propose in this regard.
Btw, no value is provided for parameter LCCN in either of those two locations, nor at WikiData: Marshall Goldsmith. That may change, whence WorldCat: and LCCN: links may or may not be displayed here.
Btw and fwiw, many many uses of template {{worldcat id}} occur in External links sections of our biographies wherein the same WorldCat link is displayed by template {{authority control}}. There may be little redundancy in effect, for most visitors, and I feel sure there is none in big sections. For instance see Aristotle#External links (whose worldcat links are broken for me now).

Auto-archiving?[edit]

It might be time to think about auto-archiving, perhaps by year; if I'm reading this correctly, {{Automatic archive navigator}} can handle such archives. —SamB (talk) 17:59, 25 February 2014 (UTC)

Done; using Miszabot. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:36, 25 February 2014 (UTC)
That worked! 30 topics were archived. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 15:18, 26 February 2014 (UTC)
14 days seems short to me. In the event, however, the latest activity in Archive 1 is almost 90 days old, 4 December 2013.
Can it be advanced manually to Archive 2 now? --in effect, turnover with the new year as SamB suggests above. --P64 (talk) 19:42, 26 February 2014 (UTC)
It's 14 days or three threads, but feel free to extend it if you think that's better. I don't see any need to manually bump the archive page number, we don't do that for other pages which are similarly archived by a bot; and besides the archives are searchable.

Suggestion for EIDR to be added to Authority control[edit]

I would like to suggest that the EIDR schema is added to the https://en.wikipedia.org/wiki/Template:Authority_control. EIDR is an industry-standard database (see http://eidr.org/membership/) that might provide a controlled vocabulary for media assets. ISAN is part of many of the cross-referenced IDs. BrillLyle (talk) 20:57, 25 April 2014 (UTC)

Is there a large public database where we can look up, check and validate EIDR numbers? Stuartyeates (talk) 02:40, 26 April 2014 (UTC)
There is! https://ui.eidr.org/search, and click on "Show More Fields" BrillLyle (talk) 15:47, 26 April 2014 (UTC)

ORCID outreach event/ codefest[edit]

I shall be attending the ORCID Outreach Meeting and Codefest in Chicago on 21-22 May; in part to speak about the use of ORCID in Wikipedia & Wikidata. If anyone has any suggestions or questions, I'll be happy to raise them there. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 17:00, 30 April 2014 (UTC)

Bot[edit]

Is there any reason we can't get a bot to move AC values from the {{authority control}} template to Wikidata? Can User:Magnus Manske help? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:09, 12 May 2014 (UTC)

ResearcherID[edit]

The ResearcherID and |MBA= parameters have to be entered on Wikipedia; they're seemingly not populating from Wikidata. Can we fix that? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 21:03, 13 May 2014 (UTC)

This template is now also on Wikidata[edit]

A version of {{Authority control}} is now on Wikidata, for use on the user pages of those of you who edit there. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:21, 21 May 2014 (UTC)

Wikipedian in Residence[edit]

As of today, I am Wikipedian in Residence at ORCID. The role is described in Announcing ORCID's Wikipedian-in-Residence. Please let me know if I can assist you, in that or any other capacity. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 17:28, 10 June 2014 (UTC)

Issue with LCCN[edit]

How does the International Standard Name Identifier fit into this approach?--DThomsen8 (talk) 14:37, 6 October 2014 (UTC)

Issues with LCCNs not being valid[edit]

I keep having difficulties adding a LCCN number to the template. I am formatting them correctly, (i.e., LCCN=no/2014/028264‏‏) but I keep error messages that the LCCN is not valid. This has been happening for a while now. I find that if I keep copy/pasting the number eventually it will accept it but I don't know why it's so buggy. Thanks for any insight! Nashona (talk) 15:38, 22 October 2014 (UTC)

You may be inadvertently copying hidden control characters from your source. Try manually typing the number. Better still, add the values to the corresponding entry in Wikidata, and not here. That way, they are magically included here, but are also available to Wikipedias in up to 280+ languages. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 15:59, 22 October 2014 (UTC)
I have also manually typed the data. Still doesn't like it sometimes. So how do you add this info in Wikidata? Been looking at Wikidata for an hour and can't figure it out. Thanks. Nashona (talk) 22:45, 22 October 2014 (UTC)
Try wikidata:Wikidata:Tours; let me know (on my talk page, rather than here) if you have any questions, after running through the tutorials there. Don't forget, once you've got the data into Wikidata, you need {{Authority control}}, with no parameters set, in the article here, to make the data visible. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 07:59, 23 October 2014 (UTC)

Authority Control Query[edit]

Hello, How do I assign an Authority Control to a biographical page and what should be the process. Please advise Ryder212 (talk) 19:16, 26 November 2014 (UTC)

The basic syntax is: {{Authority control|VIAF=xxxxxxxx}} where you replace xxxxxxxx with the VIAF number. To find the VIAF number, you go to VIAF.org, change the drop-down box from "All headings" to "Personal names" and look up your subject. For example, if I want to get the number for José Ortega y Gasset, I type in: Ortega y Gasset, and I get a results page saying 13 headings found for Ortega y Gasset. Looking at the entries, I see that the one I want is no. 2. I click anywhere on that heading and I get sent to a page detailing the various headings. After the four forms of names in boldface (the third one in Hebrew), I see it says VIAF ID: 95155380 (Personal). That number is the information you want. Then I plug it into the syntax to get {{Authority control|VIAF=95155380}}. (If I want to be really elaborate I can go to the various authority files and get the individual numbers for particular national libraries.) That template goes directly before the categories at the bottom of the page. If you have problems, give us a link so we can see what's the matter. Good luck! kosboot (talk) 03:56, 27 November 2014 (UTC)
Why add the VIAF in Wikipedia? Should that not go to Wikidata? Also, if there is an ISNI, then probably it is better to use the ISNI instead of the VIAF. John B. Sullivan (talk) 16:01, 18 December 2014 (UTC)
No, it is not "better to use the ISNI instead of the VIAF". What poppycock. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 16:21, 18 December 2014 (UTC)
Be very sure that the AC record is for the same person as the Wikipedia page, and not just someone with the same name. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:39, 27 November 2014 (UTC)

VIAF linking to English Wikipedia[edit]

LCCN does not show up[edit]

I've created articles for many scholars, and the authority control template works fine most of the time. However, I've encountered a couple cases where an author's LCCN exists, but does not show up when entered into the template. See Kang-i Sun Chang, for example. Li Yining used to have the same problem, but was automagically fixed. Anyone knows why? -Zanhe (talk) 00:29, 20 February 2015 (UTC)

I suppose it was "automagically fixed" in the browser-rendered footer Li Yining#External links when the value was imported by WikiData as value of its parameter 'LCNAF identifier'. --Only minutes before your report here yesterday, as I understand the WD page history.
The browser evidently displays values assigned at WikiData for those {Authority control} parameters not defined here. And the use of lowercase 'lccn' meant that LCCN, or LCNAF identifier, was not defined here. Proper uppercase local assignment such as 'LCCN=n/99/5' obviates/overrides WikiData (in this case, only because 'n/99/5' has a valid interpretation). --P64 (talk) 22:17, 20 February 2015 (UTC)
I fixed that for Kang-i Sun Chang whose problem was lowercase parameter name lccn. Not mentioned in the summary, I added the parameters GND and SUDOC whose values I glimpsed at VIAF: 32025323.
genuinely 'automagical'? when Wikidata creates?

: --P64 (talk) 01:04, 20 February 2015 (UTC)

technical interjection (Help!) I did not complete the last thought because of an occasional problem --most likely a Windows 7 problem, I guess. By some inadvertent keystroke(s) I toggled use of the keyboard to another character set --probably for Arabic script, I guess. Always for me the consequence is that I abort a session --frequently with one or several Arabic(?) characters as edit summary --because Ctrl-Z does not undo the toggle.
The initial colon (:) in my signature line may be a clue to you. In the composition window now I see that colon (:) as slightly different from the others, but only by close study, prompted by the browser-rendered version in which that line begins flushleft with a visible colon. Probably I entered that colon from the keyboard after the inadvertent toggle to "Arabic", I guess.
--P64 (talk) 20:08, 20 February 2015 (UTC)

FWIW, I think it's a better choice to put the authority control data on Wikidata and let the {{Authority control}} template grab it from there rather than hardcoding the data here. —David Eppstein (talk) 01:12, 20 February 2015 (UTC)

Thanks for your help! Didn't know the parameters are case-sensitive. -Zanhe (talk) 01:16, 20 February 2015 (UTC)
Hm, how would one put the authority control info in Wikidata - or does this need to be agreed upon across-the-wiki? kosboot (talk) 02:15, 20 February 2015 (UTC)
Go to the Languages => Add Links (or Edit Links) thingy in the bottom left corner of the window, use it to go to a Wikidata item for your article, add information to the Wikidata item (here's one you could model the format of the information after), and then just use the Authority control template without any arguments. —David Eppstein (talk) 02:50, 20 February 2015 (UTC)
For a page such as our Li Yining, created by Zanhe one year ago, and now linked via WikiData to French- and Chinese-language pages, there are significant obstacles to providing data there --either providing at WD instead of here, as for LCCN on David Eppstein's suggestion, or providing there in parallel as for birthdate. The WikiData project has not done a good job re those obstacles and should not expect EN.wiki content editors to overcome them. (Visitors to this talk page are likely to be at least part-time specialists in metadata such as LCCN, from whom more may be expected. But WikiData should do more for everyone. For one, provide a warning that one's IP address will be recorded in the page history, as Wikipedia does. But the extra login will remain an obstacle.)
For a new EN.wiki page such as our Kang-i Sun Chang, created by Zanhe last week, there are great obstacles to the parallel provision of data to WikiData. Most should leave it to the specialists (first of whom is a robot, I infer).
If you're going to do this regularly, the multiple login thing can be fixed so that you only log in once to all Wikimedia projects. See Wikipedia:Unified login. —David Eppstein (talk) 22:54, 20 February 2015 (UTC)
User:Zanhe (two paragraphs): Evidently you have mastered some lesser obstacles WD and may be a relevant expert in one respect. As I understand the history, you linked our new page Li Yining to WikiData on the day you created it (WD Li Yining difference 2014-01-30). Only two days later some IP visitor added a link to the older French stub fr:Li Yining (probably an experienced WP editor who overlooked the extra login required).
If there is a ZH.wiki page for Kang-i Sun Chang, of a certain age, there will be a WD item. Find it as Zanhe last year found Li Yining there (WD Q8460642 version 2013-11-21) --by appropriate Chinese character search I suppose. If there is no WD page for Kang-i Sun Chang (probably in this case because there is no page for her, or only a recent one, at ZH.wiki), that is another of the great obstacles. A new Item must be created.
Eventually WD will add a new item for Kang-i Sun Chang by reference to the new EN.wiki biography Kang-i Sun Chang. Automagically, I suppose. The history of WD Li Yining shows it was created 2013-03-27 by SLiuBot with the link to ZH.wiki and two substantial claims. --P64 (talk) 21:43, 20 February 2015 (UTC)

Sparse (duplicate) clusters[edit]

What to do with VIAF identifiers when there are more than one cluster in VIAF due to negative matching which results in sparse (duplicate) clusters containing only one national authority record?

Hi all, I would like to know what is the general policy regarding adding VIAF identifiers in Wikidata when in VIAF there are more than one cluster and the local record identifier has not been matched with the richest VIAF cluster, so that it is isolated, forming a new VIAF cluster. Example: in the italian Wikipedia, the entry about Barack Obama at https://it.wikipedia.org/wiki/Barack_Obama has the VIAF Identifier: 305358548 which is different from the VIAF identifier added in other Wkipedias. For example, in the English Wikipedia, the entry about Barack Obama at https://en.wikipedia.org/wiki/Barack_Obama has the VIAF: 52010985. In the case of the Italian Wikipedia, the VIAF: 305358548 has been added because it is the identifier of the VIAF Cluster formed only by the Italian authority record coming from the national union catalogue (identified by the code SBN: see VIAF at http://viaf.org/viaf/305358548/) As a consequence, now in Wikidata the record about Barack Obama has 2 VIAF identifiers: 52010985 and 305358548 See at https://www.wikidata.org/wiki/Q76 Is this policy correct? Or in these cases entries in all Wikipedias should have the same VIAF identifier as the English Wikipedia? In other words: Wikidata records should have only one VIAF identifiers or they can have more than one VIAF identifier? In these cases, why the corresponding entry in Wikipedia has only one VIAF identifier? --Pierfrancominsenti (talk) 18:21, 22 February 2015 (UTC)

I believe it's OCLC's idea that eventually disparate entries such as Obama's will eventually be clustered. (In this case it's obvious that the 52010985 entry will remain the main one, but I've seen others that are more ambiguous.) I've asked them and they've reminded me that VIAF is still an experiment where confirmed workflows (such as clustering) have not yet been solidified. kosboot (talk) 18:54, 22 February 2015 (UTC)
The short answer to problems with VIAF, is to contact your local VIAF-participating agency and get them to correct it. Stuartyeates (talk) 22:03, 22 February 2015 (UTC)
I guess I assumed that everyone knew that VIAF is a product of OCLC. They will correct some things, but other things they'll leave alone (I've asked them to cluster names in the past and they've not done any action). kosboot (talk) 22:36, 22 February 2015 (UTC)
VIAF is a 'product' of the OCLC, but local national libraries are responsible for the individual entries. The people at NLNZ have been very appreciative of me sending them corrections for New Zealand people. Stuartyeates (talk) 00:26, 23 February 2015 (UTC)
So the problem is not that the Italians had a different name for Barack Obama, but that it simply is not clustered with most other countries. That's not anything the Italians can do, since VIAF is all in OCLC's hands. kosboot (talk) 00:42, 23 February 2015 (UTC)
I know that VIAF is still an experiment etc. But I'm afraid you may not have understood my question which is simply referred to a Wikipedia/Wikidata policy: that is: what in your opinion is more advisable to do in Wikidata/Wikipedia in these cases? For example, in the case of the Italian entry for Barack Obama, do you think that it would be more advisable to add the VIAF identifer more used, the same added to the English Wikipedia, then 52010985, or is it better to add the VIAF identifier that at the moment is connected to the Italian national identifer, then 305358548? Or is it indifferent? But if we add the VIAF identifier for a sparse record, is there any synchronization mechanism which may garantee that in the future, when VIAF is corrected and contain only 1 cluster, even the Italian Wikipedia will be authomatically corrected? Or there is no some mechanism of the kind? And final question/doubt: is it advisable to add to the record in Wikidata more than one VIAF property? --Pierfrancominsenti (talk) 10:31, 23 February 2015 (UTC)
I would think that eventually the two will be clustered. But for now, I think it advisable to use the 52010985 identifier. kosboot (talk) 12:23, 23 February 2015 (UTC)

I would use VIAF=52010985 in biogrpahy pages, same as Kosboot.

Once [for one WikiData page] I added multiple VIAF identifiers at WikiData (rather than report them at Wikipedia:VIAF/errors#Parallel VIAF clusters for one identity) --as an experiment that I didn't pursue, and I don't recall where I may have noted the relevant facts!

During the few years I have attended to identifiers in biographies at EN.wiki, and occasionally DE.wiki:

  1. For several months covering dozens of VIAF mergers it was always true that redirection rather than deletion of VIAF pages preserved our links to VIAF. In the example given, VIAF=305358548 would be redirected to VIAF=52010985 (or vice versa) after the merge so that the footer links from EN.wiki and IT.wiki to VIAF would both target the merged cluster at least indirectly.
  2. Later for some months I noticed that dozens of footer links to VIAF had been broken by mergers, evidently as VIAF pages had been deleted rather than redirected.

For some months now I have noticed at least several redirect targets [1] and no missing targets [2] at VIAF. But the numbers are small. Anyway, I don't know whether my experiences reflect any changes in VIAF policy or practice, maybe no more than variations among VIAF workers whose assignments variously match my attention. --P64 (talk) 21:42, 13 March 2015 (UTC)

(continued a few days later -P64) Checking the source I see that WikiData does endorse multiple VIAF entries. That is, violation of the "single value" constraint is permitted for property 214, VIAF. "Exceptions are possible as rare values may exist: Jean-Louis Foncine (Q3166765)" --WikiData:Property_talk:P214.
To me that exception evidently welcomes thousands. The three VIAF values for WD Q3166765 represent one person by pagename Jean-Louis Foncine, by pseudonym Charles Vaudémont, and by birth name Pierre Lamoureux. The U.S. national library, and from 2014 the German, do commonly authorize multiple identities such as these --ie, they issue distinct ID numbers by policy, not by mistake-- and VIAF routinely bundles them separately.
WikiData:WikiData:Database reports/Constraint violations/P214#"Single value" violations now shows "3690 violations (+1 exceptions)". This shows that WikiData has made no progress identifying exceptions, and faces a long backlog. There is no reason to suppose genuine exceptions are rare.

Update[edit]

Can someone update the counts in the fourth paragraph? - PKM (talk) 01:21, 9 March 2015 (UTC)

Coverage of Wikipedia redirects[edit]

User:Vycl1994 provided this edit summary for Wikipedia:VIAF/errors yesterday:

I placed a VIAF dataset corresponding with Haemmerling's pen name Curt Moreck on the Moreck redirect, but was reverted at de.wiki. Is it against rules there to place templates on redirects?

Vycl: At German/DE Wikipedia you added the template {Normdaten} or de:Vorlage:Normdaten to the Curt Moreck redirect (diff 2015-03-01). The edit summary doesn't show, and I doubt, that editor de:Benutzer:Horst Gräbner understood your intention to add one rendition of {Normdaten} to that redirect, representing the pseudonymous identity, with parameter values all distinct from that rendition in the footer of the target article (de:Konrad Haemmerling#Weblinks), representing the overt identity under real name.

As I understand the bottom line, DE.wiki does not place {Normdaten}, nor other people external link templates such as {DNB-Portal} and {British council}, on redirect pages. That pertains not only to redirects that represent alternative identities for people whose biographies are the targets, but also to other people redirects. Nor do we do so, as I understand. No template {{Authority control}}, nor {{VIAF}} and {{Worldcat id}} &c, should be placed on any redirect pages. Neither redirects that represent alternative identities of their targets such as Emily Jenkins, nor those that do represent a person primarily and do carry people categories, such as redirect Janet Ahlberg.

From another perspective, as I understand, WikiData does not cover Wikipedia redirects. There is a page for Janet Ahlberg at WikiData because she has a Norwegian/NO biography of her own (not joint with collaborator-husband Allan Ahlberg, as our article), namely no:Janet Ahlberg. Because she has no biography in another language, and WikiData doesn't cover redirects (WD Janet Ahlberg doesn't link our R to joint biography), that NO biography lists no other-language links in the left margin (Språk).

Here at EN.wiki i have seen mention of WikiData debate about coverage of Wikipedia redirects, but I don't know where it is. (Debate probably more than a year ago, tabled or concluded "not ready yet".)

--P64 (talk) 18:54, 21 March 2015 (UTC)

P.S. Husband-collaborator Allan Ahlberg does have a trivial page at PL.wiki as well as the NO biography no:Allan Ahlberg, so the latter page does list one other-language links in the left margin (På andre språk: Polski).

Links from these NO and PL pages for the Ahlbergs to our joint biography Janet and Allan Ahlberg can be created manually, perhaps best as External links in the article footers. I don't know the recommended format even here at EN.wiki. --P64 (talk) 19:04, 21 March 2015 (UTC)

@P64: User:Mirokado and I have discussed this at my talk page one month prior to this discussion .This section of WP: Authority control was brought to my attention.

There are many cases when topic in wikipedia does not match the topic in the authority control system (see for example Category:Redirects from pseudonyms for examples of people with more than one name and Category:Articles about multiple people for examples of articles about multiple people). In these cases, the {{Authority control}} template should be put on the page (article or redirect) that most closely matches the topic in the authority control system. If necessary, create a new redirect to carry the template.

That is why I have been placing {{Authority control}} templates on redirects at EN.wiki. I erroneously thought the same would apply at DE.wiki, but was mistaken. However, it seems that placing {{Authority control}} on English redirects is not wrong. Vycl1994 (talk) 22:17, 21 March 2015 (UTC)
What do you think you are accomplishing by placing that template on a redirect? It's not a place where people can view the authority control data, because most readers are not even going to see the redirect page. I think the only things that should go on redirects (beside the redirect itself) are in rare cases categories and interwikis (when those make more sense for the redirect name than for the target name) and "{{R from..." templates. —David Eppstein (talk) 22:33, 21 March 2015 (UTC)
We do use template {{DEFAULTSORT}} on redirect pages, to ensure for example that Janet Ahlberg shows up under A in Category:British children's book illustrators (displayed italic because that page is a redirect).
David Eppstein: if i understand correctly you would place manual interwiki links on our EN redirect Janet Ahlberg and the NO article no:Janet Ahlberg. Right?
We may hope that a robot will replace such interwiki links (2) by a link (1) from WD:Janet Ahlberg, section Wikipedia, to the EN redirect --not long after WikiData agrees how to incorporate redirects. (If so, there is a parallel case for adding {Authority control} to our redirects from people; it will alert whatever WD robots monitor use of the template for purpose of creating new WD pages/items, and will provide some authority ID for upload to WD as well.)
Vycl: More than a year has passed since any WD discussions whose mention at EN.wiki I vaguely recall. I believe I confirmed at the time that the Category intersection [the link target is a tool; set Depth=1] of Redirects from people [size ~1000] and Wikipedia articles with VIAF identifiers was null. Now the intersection is merely 9 pages, alphabetically from Albert Maysles (your recent work, Vycl1994) to Stanislaw Burzynski. The latter is 15 months old, since the template was moved from the target page diff where VIAFbot placed it about 30 months ago diff.
Unless I made some mistake with the tool just now, the intersection of VIAF identifiers with Redirects from pseudonyms [size ~500] is still null now.

I created https://en.wikipedia.org/w/index.php?title=David_Millar_%28museum_director%29&redirect=no just the other day. The redirect links the authority control record with our coverage of the individual. Stuartyeates (talk) 20:24, 22 March 2015 (UTC)
Stuart, I added the line {{Redr|from person|to section}}, so your page is now in cat Redirects from people [Depth=0] and the intersection reported above should be 10 pages. (It takes some time and heat to intersect categories, especially the super-size VIAF identifiers, so I do not check. The setting Depth=1 covers pages that under the category at depths 0 and 1.)
A new redirect page should be placed in at least one redirect category. WP:RCAT is the place to begin. A new person redirect should be placed in article category Living people, or one of its siblings depending partly on its placement in Births by year and Deaths by year. WP:LIVING is the place to begin. --P64 (talk) 23:05, 22 March 2015 (UTC)

I visited the 9 pages that were in categories {R from people} and {Wikipedia articles with VIAF identifiers} hours ago, reported above. Seven (7) date from the recent work by Vycl1994 and Mirokado; two from 2014, Stanislaw Burzynski and Fanny Holcroft. I made some improvements here and at WikiData but did not change our nine redirects in the respect at stake here, as I understand: all carry template {{Authority control}} and some carry {{Persondata}}. Only one is now badly fouled at WikiData, where WD:Kevin Kopelow and Heath Seifert links the duo at EN and ES but also links fr:Kevin Kopelow. (Heath Seifert has a WD page, whose relation to the duo page I fixed.)
Good night. --P64 (talk) 23:55, 22 March 2015 (UTC)

(I just noticed this section) Policy on de.wiki is to place no content primarkly intended to be visible to users on redirect pages. Therefore the (formerly invisible) templates de:Template:Normdaten and de:Template:Personendaten are alright on a redirect page (there must be not more than one of that kind on the target page), and de:Template:DNB-Portal ist not allowed (intention is to provide user-clickable weblinks, several of them are allowed on the target page, provided they differentiate themselves by the appropriate name and type parameters). Usually cases like that can also carry categories on the redirect pages and should be instances marked as __STATICREDIRECT__ (the entity the redirect page stands for is distinguishable from the entity connected with the target page). Sadly on de.wiki the community usally will always "optimize" away any double redirects, regardless of the state they declare. -- Gymel (talk) 15:11, 27 March 2015 (UTC)
Help:Magic words tersely states how __STATICREDIRECT__ switches the behavior of Wikimedia software. Should we use it to distinguish redirects that represent their objects? Do others use it that way?
On those two kinds of redirect pages here at EN.wiki I now provide WP:COMMENT explanation and instruction as at Edgar Parin d'Aulaire and Edgar Parin D'Aulaire. (I store a completed A.c. template elsewhere, usually; never create a redirect talk page for the purpose.) --P64 (talk) 15:45, 27 March 2015 (UTC)
Few of our Redirects to joint biographies carry STATICREDIRECT. It is common among those that carry inter-language links (in turn, usually DE.wiki). For instance see Tim Hildebrandt. --P64 (talk) 01:06, 31 March 2015 (UTC)

Biblioteca Nacional de Chile work and people authority control[edit]

I'd like to suggest adding the Biblioteca Nacional de Chile authority control IDs to this template. There is plenty of Chileans (and non-Chileans too) who have a record in their catalog, and also of an infinity of publications, including newspapers, magazines, maps, and photographies, recordings, etc. I have already proposed the creation of a Wikidata property. --Diego Grez (talk) 03:18, 13 May 2015 (UTC)
