Unique constraint

The unique constraint seems to be inappropriate here. It is unlikely that we will (typically) have distinct items for print vs online versions of a periodical, as the majority of the facts about both editions is the same - the main difference is that articles have two issued dates: first online and then in print. That difference is an attribute of the article, rather than of the periodical. John Vandenberg (talk) 00:27, 25 February 2014 (UTC)

11000 "single value" violations out of 28000 periodicals - all having two IDs: electronic + paper IDs. We need to suppress that constraint for now. Could be reinstated if there eventually exist a "one or two" constraint... LaddΩ chat ;) 23:26, 15 March 2014 (UTC)

You can see how it is done in Acta Arithmetica. The restriction says it has to be a unique value except if there is one of the following qualificators: applies to part (P518), start time (P580), end time (P582), language of work or name (P407), distribution format (P437) or publisher (P123). For printed and online versions, you can use distribution format (P437) with printed matter (Q1261026) and online publication (Q1714118). Paucabot (talk) 10:21, 17 October 2020 (UTC)

E-ISSN (electronic ISSN)

Looks like we need divide this property to two properties: electronic ISSN and paper ISSN. — Ivan A. Krestinin (talk) 08:09, 16 March 2014 (UTC)

I think the next step is to add a property for 'ISSN-L', which is constrained per the new (2007) ISO standard as having a single value for each journal. It will be very rare that we have two items with the same ISSN-L - so rare that the constraint exceptions list is sufficient to deal with them.

I have been thinking that perhaps the ISSNs should have a qualifier, instead of multiple properties, as it allows more flexibility.

I personally dont see the benefit in having distinct properties for electronic ISSN vs paper ISSN. Most of the time when people look up an ISSN, they dont care whether it is the ISSN or eISSN. The electronic version of the article (eISSN) and the digitised print version of the article (ISSN) are usually almost identical. However if someone puts together a well designed solution using multiple propertyies, I will support and help implement it.

Two issues to consider:

1. Periodicals can also have CDROM ISSNs, which should probably be recorded on the main item for the journal. These are mostly given to conferences rather than journals, but Physical Review Letters (Q2018386) does have a CDROM ISSN.
2. Periodicals can also have additional ISSNs (paper & electronic) for special editions, supplement, etc. These vary so much it is hard to say whether a rule can be written to say whether the special edition should a separate item or be part of the main item for the journal. Some supplements are very distinct works; others are only published once in place of a normal issue by the same team and most readers consider it to have been an odder-then-usual issue but not a separate work. However if they are a separate item, how do we link it to the main item, and should the special issue item have an ISSN-L property?

John Vandenberg (talk) 00:33, 18 March 2014 (UTC)

I think we should divide to ISSN, eISSN, and ISSN-L. Many bibliographic systems have that distinction, eg PubMed XML has:

• Journal/ISSN with attribute @IssnType (Electronic | Print)
• MedlineJournalInfo/ISSNLinking

--Vladimir Alexiev (talk) 11:50, 20 February 2019 (UTC)

Since this conversation, Wikidata has settled on using ISSN (P236) with the qualifier distribution format (P437) with the following values printed matter (Q1261026) or online publication (Q1714118). Daask (talk) 15:42, 9 October 2024 (UTC)

too many resolvers

This prop has 4 formatter URL and 7 third-party formatter URL. I understand these different databases include different journal lists, but I need some guidance on "which is better" (what is their respective coverage).

@John Vandenberg, Ivan A. Krestinin: maybe you can help? Also asked at https://en.wikipedia.org/wiki/Wikipedia_talk:WikiProject_Academic_Journals#ISSN_Resolvers --Vladimir Alexiev (talk) 11:56, 20 February 2019 (UTC)

The "official one" is https://issn.org/resource/ISSN/$1, the official documentation for URL/URI can be found at http://www.issn.org/understanding-the-issn/assignment-rules/issn-linked-data-application-profile/ (to be added as a reference for this resolver, but I can't do it - can someone do ?) http://www.issn.cc seems to be dead.  – The preceding unsigned comment was added by Tfrancart (talk • contribs) at 12 September 2019 (UTC).

Online ISSN and Print ISSN

The most popular choice to distinguish between online and print ISSN is to use

• distribution format (P437)printed matter (Q1261026) for print
• distribution format (P437)online publication (Q1714118) for online

as qualifiers:

select ?format ?formatLabel (count(?i) as ?count) (sample(?i) as ?sample) {
  ?i p:P236 [pq:P437 ?format].
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
}
group by ?format ?formatLabel
order by desc(?count)

Try it!

--Haansn08 (talk) 06:17, 1 June 2020 (UTC)

OK. Also, one can search references like this: https://query.wikidata.org/#SELECT%20%3Fissn%20%3Fstatement%20WHERE%7B%0A%3Fstatement%20prov%3AwasDerivedFrom%20%3Fref%20.%0A%3Fref%20pr%3AP236%20%3Fissn%20.%0AFILTER%28regex%28%3Fissn%2C%220034-0375%22%29%29%7D --2601:281:D87E:D6E0:2CBD:7AA4:AA5C:6B1E 06:57, 15 July 2024 (UTC)

Serials without ISSNs

Is there a way to denote a work that does not have an ISSN? For example the British journal The Electrical Engineer (Q105221968) appears not to have one (the unrelated but roughly contemporaneous New York The Electrical Engineer does). I set it to "no value" - is that right? Should there be a reference or "as of" qualifier? Inductiveload (talk) 14:06, 3 February 2021 (UTC)

The Electrical Engineer (Q105221968)ISSN (P236)no value Help looks fine to me. Adding a point in time (P585) qualifier would be nice, but isn't necessary. Again, a reference would be nice if one is available, but isn't necessary. None of the reasons listed in Help:Sources/Items not needing sources applies, so in theory it should be referenced, but many editors are content to regard an uncited claim as being implicitly referenced to you as the contributor who added the claim. More useful than any of the above would be to add the New York The Electrical Engineer as the object of different from (P1889) Daask (talk) 15:24, 9 October 2024 (UTC)

Resolver problem ?

There seems to be a problem with resolving the URL. Is it only for me ? For example Problemy Polityki Społecznej. Studia i Dyskusje (Q96728398). Rendered correctly in page source but opens the Wikidata Main Page instead. Kpjas (talk) 07:41, 16 October 2023 (UTC)

@Kpjas: It works for me. Did you try it in safe mode? If it’s broken without safe mode but works in safe mode, then the breakage is likely caused by a gadget or user script you enabled. —Tacsipacsi (talk) 08:47, 17 October 2023 (UTC)

"country of origin" qualifier

An error says I need to add the country of origin qualifier if I add that, it says it isn't allowed. Can anyone fix this? Dentsinhere43 (talk) 09:33, 22 July 2024 (UTC)

@Dentsinhere43:. Wikidata items with ISSN (P236) should also have country of origin (P495) as a separate statement, not as a qualifier to ISSN (P236). I think you misread the error message. Daask (talk) 15:35, 9 October 2024 (UTC)
