Periodical series[edit]

Im sorry if this question has been raised elsewhere. I would like to know how to best record that Trends (Q787045) is a series. I have use 'part of' for all the journals in the series (see Special:WhatLinksHere/Q787045). Do we need a new item called 'journal series', which is a subclass of brand (Q431289)? Another example is BMC journals (Q4835951) (See enwiki list), but there are many of these series which have an article on Wikipedia, as English Wikipedia editors have often wanted an article to link to, but not wanted to write a new stub for each journal in the series. John Vandenberg (talk) 10:03, 2 December 2013 (UTC)

Some more examples are Chemische Berichte (Q902474), Journal of the Chemical Society (Q903605), and Proceedings of the Royal Society (Q1193201). John Vandenberg (talk) 10:23, 3 February 2014 (UTC)
More examples: Perkin Transactions (Q7169012), Environment and Planning (Q2813257), Comptes rendus de l'Académie des sciences (Q2667573), Acta Crystallographica (Q343155). John Vandenberg (talk) 02:34, 4 February 2014 (UTC)
More examples: American Journal of Medical Genetics (Q4744254), International Journal of Modern Physics (Q1666666) John Vandenberg (talk) 02:55, 6 February 2014 (UTC)

I am thinking of giving all these an instance of a new item 'academic journal imprint', which would be a subclass of imprint (Q2608849). Other periodical types would need their own subclass. Requesting feedback. John Vandenberg (talk) 02:21, 8 February 2014 (UTC)

Sorry, I have no idea how to solve this problem, but I think we shouldn't invent new terms. Imho there would be no good translating for "academic journal imprint", since the term "imprint" is used in many languages (probably with different connotation). --Kolja21 (talk) 03:31, 8 February 2014 (UTC)
Thanks for replying. We need a structural element - I don't mind what we call it, and the name can change later. The above examples are a publishing brand more than anything else, but maybe using 'imprint' is too inventive ;-) e.g. Trends (Q787045) should have a property 'imprint'=>Cell Press (Q5058164), and publisher=>Elsevier (Q746413), but we dont have an 'imprint' property.
"Trend journals" are commonly called the "Trend journal series", I don't like "journal series" as a generic name, the word 'series' is too ambiguous. e.g. Proceedings of the Royal Society A (Q10354104) is often called "Proceedings of the Royal Society of London. Series A", so it would be confusing to call Proceedings of the Royal Society (Q1193201) a series. I'll ask for help from w:WP:AJ. John Vandenberg (talk) 04:28, 8 February 2014 (UTC)
Note: w:en:Wikipedia talk:WikiProject Academic Journals#Academic journal series. John Vandenberg (talk) 04:58, 8 February 2014 (UTC)

Ah, here is a good quick fix, even if only a interim/temporary solution. We could call them a subclass of (P279) 'academic/scientific journal' rather than instance of (P31) 'academic/scientific journal'. That is what user:FelixReimann did with BMC journals (Q4835951). We would still need to define what they are an instance of, but that isnt an urgent problem. John Vandenberg (talk) 04:48, 8 February 2014 (UTC)

  • Perhaps DGG at en:WP has some helpful suggestions here, being a former academic librarian. --Randykitty (talk) 16:23, 10 February 2014 (UTC)
You do not need necessarily both, subclass of (P279) and instance of (P31). In this case, the class scientific journal (Q5633421) has subclasses BMC journals, Trends, .... Imprint is IMHO not correct, as the publisher remains BioMed Central or Cell, respectively. If we find an item "academic journal series" or whatever, we could at it as target of instance of (P31) but this is not necessary.  — Felix Reimann (talk) 10:16, 11 February 2014 (UTC)
Another option is to use series (P179). John Vandenberg (talk) 12:07, 28 February 2014 (UTC)
No as the different BMC journals for example do not have an order. P179 is for ordered things (A,B,C,D,...).  — Felix Reimann (talk) 16:48, 28 February 2014 (UTC)
  • I think it is important to realize that there is a difference between series like Compte rendus, where we have one single journal with either temporally-subsequent series or parallel series with different subjects, and "series" like Trends journals and BMC journals, which are independent journals that are similarly branded by the publisher. --Randykitty (talk) 20:18, 28 February 2014 (UTC)

Part publication of a journal article[edit]

Our Fragile Intellect (Q7110639) has a English Wikipedia page, but the publication was split into two articles, with two different DOIs, albeit published back-to-back in the same issue of the journal and on the same date (both electronic and physical). We definitely need an item for 'work' that comprises both articles, as that is the level that 'visible' to the real world, but the academic world will cite one or the other. Do we need each part to have a separate item? John Vandenberg (talk) 10:03, 2 December 2013 (UTC)

Abbreviations[edit] includes some journal abbreviation lists, such as 12. John Vandenberg (talk) 13:15, 5 December 2013 (UTC)

  • ISO abbreviations can also be found here. Randykitty (talk) 04:57, 6 December 2013 (UTC)
We might need an "abbreviation" or "short title" (baroque literature) property: Wikidata:Requests for comment/How to deal with given names and surnames. --Kolja21 (talk) 18:53, 10 February 2014 (UTC)

Template:Cite doi subpages[edit]

I've raised a question about 'Cite doi' templates at Wikidata:Project_chat/Archive/2014/01#Template:Cite_doi_subpages. --John Vandenberg (talk) 17:17, 30 December 2013 (UTC)

Original title and language for a newspaper, magazine еtс[edit]

Are there properties for a original title and language? -- Sergey kudryavtsev (talk) 09:15, 17 January 2014 (UTC)

PS: w:ru:Шаблон:Журнал uses original language of work (P364) or language of work or name (P407) in sence of a original language. -- Sergey kudryavtsev (talk) 10:54, 17 January 2014 (UTC)

@Sergey kudryavtsev: Please use no label (P357) and original language of work (P364). --Kolja21 (talk) 07:07, 4 February 2014 (UTC)

Its are not listed in Wikidata:Periodicals task force#Venue item properties, only for a article. I add no label (P357) and original language of work (P364) for sake of clarity. -- Sergey kudryavtsev (talk) 12:47, 4 February 2014 (UTC)

Conference proceedings and preprint repositories[edit]

Are conference proceedings and preprint repositories within the scope of this proposal? --DarTar (talk) 06:25, 18 January 2014 (UTC)

Definitely yes for conf-pubs. Pre-prints repos which perform like serial publications would also be within scope, as would pre-print repos which contain a high proportion of outputs which were properly published in periodical. Do you have any specific repo you are interested in? John Vandenberg (talk) 07:12, 3 February 2014 (UTC)
ACM Multimedia (Q288546) is an example of one that is both a conference and a journal, and a SIG. Do we split it into three items? John Vandenberg (talk) 02:37, 4 February 2014 (UTC)

JVbot uploading sources[edit]

JVbot 1 is nearing completion. JVbot 2 needs feedback (please be critical). John Vandenberg (talk) 07:16, 4 February 2014 (UTC)

Classes for periodicity, periodicity property ?[edit]

Hi, I created no label (Q15709838) for monthly magazines to be an instance of. Have we a relevant corresponding periodicity property to note the publication frequence for periodical publications and to define better this class ? TomT0m (talk) 22:24, 4 February 2014 (UTC)

We do not yet have a frequency/periodicity property. It is a generic property, as it applies to at least Infobox journal/magazine/newspaper and also sporting events, and awards. John Vandenberg (talk) 10:38, 5 February 2014 (UTC)
still no property for frequency/periodicity ? this is so essential for periodicals :/ --Hsarrazin (talk) 09:33, 1 June 2016 (UTC)

Invalid ISSNs[edit]

The Independent (Q1712632) has an invalid ISSN, because the paper was printed with an invalid ISSN *headdesk* (if the source provided is to be believed). There will be many of these; how do we want to represent these? If they are placed in the ISSN field, they will fill up the ISSN validation report: Wikidata:Database_reports/Constraint_violations/P236. John Vandenberg (talk) 11:00, 15 February 2014 (UTC)

Same problem with ISBN, see en:Template:Listed Invalid ISBN. We should add a qualifier. --Kolja21 (talk) 23:14, 15 February 2014 (UTC)

ERA journal lists imported[edit]

The ERA 2010 journal list (Q15735759) and ERA 2012 journal list (Q15794938) have been imported, and in the process many magazines & newspapers from the Wikipedias have been imported (but not all of them). Wikidata:Database reports/Constraint violations/P236 hasnt been updated for a few days, so I cant see how many erroneous values have been imported in the process. Over at Property talk:P236#Unique constraint, I have recommended that we remove the Unique constraint.

We now have 40539 issns in Wikidata, and 22498 eraids, which means our academic journal database is probably around 25000-30000 items.

In the process I imported some LCCNs, which has resulted in quite a few constraint violations on Wikidata:Database reports/Constraint violations/P1144. Some are badly formatted due to insufficient importing parsing logic, but that property also has a constraint requiring LCCNs are only added to books. Guidance and/or assistance much appreciated on this issue.

Scopus Source ID (P1156), CODEN (P1159), ISO 4 abbreviation (P1160), Z39.5 abbreviation (P1161) & Bluebook abbreviation (P1162) have been approved, so I will be attaching Scopus IDs & abbreviations to our journal collection next. John Vandenberg (talk) 01:47, 25 February 2014 (UTC)

April import update[edit]

I have imported all of the Danish Bibliometric Research Indicator (BFI) SNO/CNO (P1250) data for journals which have the same ISSNs are journals on the ERA list. i.e. existing items only. I havent added the Danish ID to records which do not also have a ERA Journal ID (P1058) (I will look at the other half of the Danish list next month). See previous discussion at User talk:Fnielsen#Journal aliases and Scandinavian authorities and @Fnielsen:. This has allowed me to compare journal names common to both lists. The majority of the journal titles were identical, or slightly formatted differently, and those were imported first. There were roughly 1000 which had significantly different journal names, or were otherwise skipped by my title name comparison rules. Some were title corrections, others are common aliases, but there are also many interesting ones like journal renames and names in other languages - usually the original language. The English labels were copied to languages Finnish, Danish, Swedish, Norwegian (both) and French, if they didnt already have a label in those languages.

Here are the edits to the last 1000 items.

For non-English journals, it would be great if people could add original language of work (P364) to the journal, and language of work or name (P407) to the no label (P357). I can use that to move the appropriate title into the labels of languages other than English.

We need to start establishing label preferences for each language. i.e. Wikidata house rule (Q455282)s. Should English labels use transliterated titles in preference to original language title? (Both Australian and Danish journal lists use ASCII titles). Do we remove Die, Der, El, La, L' prefixes etc? Do we use '&' instead of et, und, etc? Do we want to shorten labels by using '[Organisation]. Journal' instead of 'Journal of the [Organisation]'. When do we use an abbreviation vs including the subtitle, e.g. T C (Q15762478) can be 'TC', 'T C' or 'TC: a journal of biblical textual criticism'.

Then we need title language fallback strategies. e.g. for German journals, e.g. should Danish labels use the German or English title if both are available? For German titles, does Danish prefer the original (i.e. 'für'), or a transliteration (e.g. 'fur' or 'fuer')? The Danish journal list prefers 'fuer' whereas the Australian list usually uses 'fur'!

There are a few Danish Bibliometric Research Indicator (BFI) SNO/CNO (P1250) constraint violations listed at Wikidata:Database reports/Constraint violations/P1250. Many will be the same violations as documented as exceptions at Property talk:P1058.

There are additional ISSN (P236) violations at Wikidata:Database reports/Constraint violations/P236.

The Danish academic book publisher property was rejected at Wikidata:Property proposal/Authority control because only one person supported it. There are a few journal authority control proposals on that page which I fear will soon be rejected unless people vote for them. There are a number of journal property proposals on Wikidata:Property proposal/Creative work which also only have 'one support'. :/ The 'indexed in' property for journals at Wikidata:Property proposal/Creative work#indexed in is especially important in my opinion, and it would allow journal database ID properties (like the Scopus Source ID (P1156)) to be moved into qualifiers instead of being a claim on the data item. John Vandenberg (talk) 08:49, 21 April 2014 (UTC)

Proposed property: copyright license[edit]

See Wikidata:Property_proposal/References#copyright_license. --Daniel Mietchen (talk) 14:55, 9 May 2014 (UTC)

For the record, the discussion determined that license (P275) should be used. It would be great if a bot could import this data.
@Daniel Mietchen: I think open access policy is a property which does not yet exist. It would be a good idea to model it here at the task force first, as there are a lot of strange cases to be considered. John Vandenberg (talk) 01:02, 24 May 2014 (UTC)

Multiple language journals[edit]

Global Media Journal (Q11699954) is a fun one. It has ten different language/region editions which are all interwoven in content. Wikipedia will probably only ever have one article for them all. The US/English edition was recently merged by user:Alan ffm into the item for the Polish Wikipedia article, which of course has the Polish edition ISSN and other infobox parameters.

Other simpler cases are Angewandte Chemie (Q538683) and Chinese Physics B (Q3128474) (English language)/ Acta Physica Sinica (Q2200957) (Chinese language). John Vandenberg (talk) 00:56, 24 May 2014 (UTC)

Property with type item where item has no entry[edit]

What should we do in the situation where, for instance, an article has an author, but that author has no wikidata entry?

Options that could be done now:

  • Create a wikidata entry for the entity
  • Either wouldn't link to any wiki page (bad), or
  • Could make a wikisource entry; wikisource has a special namespace for authors (i.e. s:Author:Russell_Thorndike)- can orphan pages be created on wikisource?)
  • Use a separate author property that takes strings (potentially the least disruptive to wikidata). There is some precedent for this as there are already specialized "author citation" properties that take strings (see Q788451 ). However, this will result in messy citations and possible duplicates if authors become entities at some point.

Options that would require not-yet existing functionality:

  • Modify wikidata to allow "red-linking" within i.e. you would type in a name, which wouldn't actually point to a wikidata entry (probably involves major changes to wikidata internals and could be very problematic).

Mvolz (talk) 2014-07-20T15:20:21‎

A generic response to a generic question..
Creating an author page on Wikisource is a very good solution. It may be an 'orphan', but it should list at least one work which is 'free' (public domain, etc). Notability isnt a serious issue at Wikisource. See s:Help:Author pages for precise eligibility rules.
If the author is modern and all works are covered by copyright, and they are notable, creating a stub on a Wikipedia is also good.
String author properties are the anti-thesis of Wikidata, as we want the data rather than one representation of the data. There are many citation formats, and they specify how the name should be formatted.
'Redlink' data item is a very interesting idea, but wayyyy beyond the scope of this WikiProject ;-).
If the author isnt notable, and has no 'free' works, create a Wikidata item, and add a note on the item talk page to say that you believe the author is not (yet) notable enough for a page on any of the Wikimedia projects. Wikidata inclusion policy explicitly allows non-notable subjects if the non-notable item is not an orphan. i.e. On Wikidata, notability is inherited! John Vandenberg (talk) 00:25, 21 July 2014 (UTC)
"Either wouldn't link to any wiki page" I suppose that if the article has a Wikidata item that Wikidata item would link to the author. I was not aware of the inheritance of notability on Wikidata. I have extended Equation of State Calculations by Fast Computing Machines (Q5384234) and was not sure what to do with the two Wikipedia-non-notable authors on that paper, but as I understand on John Vandenberg it is not a problem to have items for the two missing authors on Wikidata. — Finn Årup Nielsen (fnielsen) (talk) 16:41, 21 July 2014 (UTC)

instance of (P31) and genre (P136)[edit]

For journal articles we have instance of (P31) scientific publication (Q591041) and genre (P136) scientific publication (Q591041). I wonder if that is ok or if something else should be done. — Finn Årup Nielsen (fnielsen) (talk) 16:54, 21 July 2014 (UTC)

I tried to put data on Charlie Hebdo issue No. 1178 (Q18763302) but I'm unsure how to do it.

What should we use for instance of (P31) ? I used edition (Q3331189) (like on the FRBR pattern of Wikidata:WikiProject Books) but maybe there is something better.

How can I indicate the number of issue printed (7.95 million copy, highest ever for the French press), with quantity (P1114) ?

Do you see other data to add and how ?

I have created a small website with aggregation of scholarly publication metadata from Wikidata. I can give an overview of "venues" (journals, collections), publishers and authors.
