    Formatter URL doesn't work well

    edit
    Latest comment: 8 years ago7 comments5 people in discussion

    Hi, I noticed that the URL chosen for this property works only with ISIL codes associated with Germany, but it doesn't work with, say, Italy or Switzerland. I think it would be better to remove the URL, since there is a search engine for every country that adhere to ISIL standard. --Sannita - not just another it.wiki sysop 18:19, 5 April 2015 (UTC)Reply

    I agree, otherwise the "International" in ISIL seems overly limited. --Steko (talk) 08:56, 24 August 2015 (UTC)Reply
    You might want to add custom code to MediaWiki:Gadget-AuthorityControl.js. --- Jura 09:22, 24 August 2015 (UTC)Reply
    Just encountering the same issue for Danish Libraries. The alternative to remove the Formatter URL, would be to have several Formatter URL and then qualify them with Country? --VicVal (talk) 19:22, 19 November 2015 (UTC)Reply
    Yes, changing AuthorityControl.js shouldn't be too complicated. I hope to get this included in the new formatter url version as well. --- Jura 19:41, 19 November 2015 (UTC)Reply

    Not all registration authorities maintain web registries. Some are simple lists in PDF or other formats. Some have no public lists at all. See the "List" and "n/a" entries here: http://biblstandard.dk/isil/ Note that this doesn't make it any less of an identifier or any less important. Tfmorris1 (talk) 18:56, 8 June 2016 (UTC)Reply

    New Formatter URL

    edit
    Latest comment: 4 years ago6 comments3 people in discussion

    Dear administrators!

    Please consider to change the Formatter URL from http://dispatch.opac.d-nb.de/DB=1.2/CMD?ACT=SRCHA&IKT=8529&TRM=$1 to https://w3id.org/isil/$1 with a value (?:DE|ZDB|US|IT|JP)-.* for the "format as a regular expression" property. Since I'm not allowed to change this.

    This way not only German but also US, Italian and Japan ISILs will be linked.

      Done This is what we were expecting, thank you very much! --Sannita - not just another it.wiki sysop 11:14, 28 November 2017 (UTC)Reply

    • That seems problematic as it's a third party redirect service. We can add more in the gadget instead. BTW, even if it's added, former information shouldn't be overwritten.
      --- Jura 12:14, 28 November 2017 (UTC)Reply
    Up until now, only DE-* codes were allowed to function, because for some reason a Germany-only URL was provided for a service that's supposed to be international. It's a redirect, I know, but at least it works.
    Moreover, formatter URL (P1630) only allows for one value. Keeping the others as "deprecated" or using the gadget doesn't seem to me a good idea. Happy to revert my edits, as long as I see there's consensus on your concerns, not mine. --Sannita - not just another it.wiki sysop 14:05, 28 November 2017 (UTC)Reply
    As the regex aren't supported yet for external-ids, I deprecated the formatter urls. The gadget will continue to provide the links .. @Pyrog: for info.
    There is a ticket in phabricator to change this. --- Jura 20:07, 25 April 2020 (UTC)Reply

    Change of datatype

    Data type "external identifier"?

    edit

    Hi, I was wondering why this property isn't defined to expect the data type "external identifier" (https://www.wikidata.org/wiki/Help:Data_type#External_identifier). Wouldn't that fit? Best, Jana Hentschke (talk) 09:50, 20 April 2018 (UTC)Reply

    I agree, it should be changed. --Epìdosis 11:19, 2 August 2018 (UTC)Reply

    Proposal - Change Data type of ISIL (P791) from String to External identifier

    edit

    I think String is the wrong type for ISIL (P791). Can we please change it to be External identifier.

    As per Help:Data_type#Changing_datatype please indicate support/opposition below. Iwan.Aucamp (talk) 16:51, 15 October 2019 (UTC)Reply

    Proposal - Change from "Statements" to "Identifiers"

    edit

    This property is sorted in "Statements" but it is in identifiers. Thus, it should be sorted in the section "Identifier".

    See for example Library of Congress (Q131454): The property ISIL (P791) belongs to the chapter "Statement". --Eulenspiegel1 (talk) 23:12, 4 March 2020 (UTC)Reply

    Removal of single value constraint

    edit
    Latest comment: 4 years ago4 comments2 people in discussion

    Currently ISIL (P791)property constraint (P2302)single-value constraint (Q19474404). The problem is that ISIL does not make this guarantee:

    Since this document allows the use of existing codes to be incorporated into the ISIL, it is possible that a given organization can have more than one ISIL. However, it is the intention of this document to minimize the number of codes.

    ISO 15511:2019

    I guess the right solution is to remove the constraint. Please discuss below. Iwan.Aucamp (talk) 20:44, 30 April 2020 (UTC)Reply

    Again on formatter URL (P1630)

    edit
    Latest comment: 7 months ago12 comments5 people in discussion

    It so happens that we have found a way to give access to all national sub-catalogues for libraries with the address https://w3id.org/isil/$1, that automatically redirects users to the particular national website.

    My proposal is to remove all other formatter URLs, since they cannot work with current datatype and, given the solution provided by a World Wide Web Consortium (Q37033) group, they might induce people to add a potentially infinite list of links that are to be considered deprecated on Wikidata. --Sannita - not just another it.wiki sysop 10:28, 6 May 2020 (UTC)Reply

      Notified participants of WikiProject Authority control--Sannita - not just another it.wiki sysop 10:31, 6 May 2020 (UTC)Reply

    Thanks for the ping. So, I think that https://w3id.org/isil/$1 works for most, but not all the IDs: e.g. https://w3id.org/isil/RU-10017011 (one of the examples) seems not working. I've already set some days ago the formatter URL (P1630) https://w3id.org/isil/$1 as preferred value, but strangely the property displays no link (maybe a bug?). While I agree about removing formatter URLs starting with https://w3id.org/isil/$1, I'm not so sure about totally removing the other ones, which I think are correct and worth mentioning; probably they should be moved to third-party formatter URL (P3303), although I'm not sure an URL like http://anagrafe.iccu.sbn.it/isil/$1 can be considered "third party". Anyway, I'm convinced that in the present situation, with https://w3id.org/isil/$1 setted as preferred value for formatter URL (P1630), the link should already appear. --Epìdosis 10:39, 6 May 2020 (UTC)Reply
    @Epìdosis: It may not have shown a link because it was a string-type property, not external id. ArthurPSmith (talk) 17:25, 6 May 2020 (UTC)Reply
    @ArthurPSmith: OK, but now it is an external-id and the link still isn't shown. --Epìdosis 17:31, 6 May 2020 (UTC)Reply
    Where are you not seeing it? The examples on the property page show as links (at least for me). ArthurPSmith (talk) 17:43, 6 May 2020 (UTC)Reply
    @ArthurPSmith: No, the examples don't show as links (at least for me). --Epìdosis 19:12, 7 May 2020 (UTC)Reply
    @Epìdosis: that's weird. Maybe you have a javascript gadget enabled that's interfering somehow? ArthurPSmith (talk) 19:49, 7 May 2020 (UTC)Reply
    @ArthurPSmith: I would exclude it, since it also happens on browsers where I'm not logged-in. --Epìdosis 20:02, 7 May 2020 (UTC) P.S. T252167Reply
    • What would be the benefits of the proposal? Is there some storage issue?
    Why not store the formatter to the original source?
    As it's feature that is somewhere planned in phabricator, it's better to keep the data.
    BTW, if redirects are possible, rather than using a third party redirector, I'd use the one on toolserver. --- Jura 11:08, 6 May 2020 (UTC)Reply
