Pauly-Wissowa, book or category?

Hi,

There is a lot of weird things with Pauly-Wissowa vol. I,1 (Q26414644). Especially with:

⟨ Pauly-Wissowa vol. I,1 (Q26414644)    ⟩ instance of (P31) ⟨ book (Q571)    ⟩
genre (P136) ⟨ encyclopedia (Q5292)    ⟩

⟨ Pauly-Wissowa vol. I,1 (Q26414644)    ⟩ instance of (P31) ⟨ Wikimedia category (Q4167836)    ⟩
category related to list (P1754) ⟨ article (Q191067)    ⟩

First these two values are kind of incompatible. Then, nor genre (P136) nor category related to list (P1754) are allow qualifiers for instance of (P31). Finally, instance of (P31) = Wikimedia category (Q4167836) triggers a lot of constraint violations on the other properties.

Could you take a look and correct it please.

@VIGNERON: I modified former item Pauly-Wissowa vol. I,1 (Q26414644). Please have a look and give me a feedback. I will change the other category items then. Greetings --2%^er 05:27, 11 February 2018 (UTC)

Thanks, now it's clearly a category. That's way better.

Just one point: I see that you put

⟨ Pauly-Wissowa vol. I,1 (Q26414644)    ⟩ category's main topic (P301) ⟨ Paulys Realenzyklopädie der klassischen Altertumswissenschaft (Q1138524)    ⟩

but you forgot the inverse

⟨ Paulys Realenzyklopädie der klassischen Altertumswissenschaft (Q1138524)    ⟩ topic's main category (P910) ⟨ Pauly-Wissowa vol. I,1 (Q26414644)    ⟩

. And I'm wondering if you should really use the general item Paulys Realenzyklopädie der klassischen Altertumswissenschaft (Q1138524) or if it wouldn't be better to use a specific item for each volume. Said in an other way, I would have split the information you had on Pauly-Wissowa vol. I,1 (Q26414644) in two items (one for the category, one for the volume) instead of just removing the information about the volume. (PS: there is the gadget moveClaim.js that can help a lot for splitting items, just add mw.loader.load( '//www.wikidata.org/w/index.php?title=User:Matěj_Suchánek/moveClaim.js&action=raw&ctype=text/javascript' ); to your page User:2%ɐ/common.js)

@VIGNERON: The problem for an item book is, that a book only exists as the category on Wikisource and a package of single side scans on Commons. This was my problem while establishing these RE entries. Maybe one should create an item not referred to a project as instance of book, all scan entries from Commons and additional information from Wikisource about editor(s), author(s) and revision(s). I remember there was a rule « create no entry without a refered wikimedia article / page » and so I dropped the book informations into these mixed wd:items --2%^er 01:33, 12 February 2018 (UTC)

Mmmh, you are the specialist for this encyclopedia so in the end, it's up to you but from my point of view, it seems that you need an item for the volumes too. « create no entry without a refered wikimedia article / page » is true but it's not limited to that, most item on Wikidata are not linked to a wikimedia page; it's only the first point of Wikidata:Notability, the point 2 and 3 allows item without Wikimedia pages if it refers to a physical that you need for other items.

Pauly-Wissowa - book better than category

Hi! Regarding the volumes of Pauly-Wissowa (list) I discovered (see) a big problem regarding the presence of instance of (P31)Wikimedia category (Q4167836): thousands of constraint violations because published in (P1433) requires instance of (P31)work (Q386724). My proposal is to remove instance of (P31)Wikimedia category (Q4167836) and add instance of (P31)work (Q386724) to all the volumes; otherwise we should create new items for volumes and substitute them to the existing category items, but this is much more problematic (thousands of edits). What do you think? Thank you very much, --Epìdosis 16:01, 18 May 2018 (UTC)
