In order to browse all "creative works" at once instead of browsing "video game" and "exhibit" separately, or to browse all "critical writings" at once instead of browsing "monograph" and "article" separately, we need to link the sub-classification item to the primary classification. We do that by assigning an internal classification item to the property cdn-class-type (P121).

cdn-class-type (P121)

Wikidata does this by using the subclass of (P108) property. We don't use that because we want our data to match what is in Wikidata, but we also want to have classifications that are simpler, broader, and more generic than what is in Wikidata.

cdn-suggested-property (P122)[edit | edit source]

When adding an statement to a creative work, we can suggested which property to use for a given value. For example, recommending programmed in (P100) when using the value JavaScript (Q98).

With critical writings or other types, use the property main subject (P26).

Item Usage Questions[edit | edit source]

anthology (Q40)[edit | edit source]

Most commonly used with form of creative work (wikidata) and not instance of (P1).

Usage count:

1597 - form of creative work
245 - main subject
242 - genre
118 - instance of

https://www.wikidata.org/w/index.php?title=Q122880588&action=history

Some actually changed instance of anthology to instance of literary work. Is an online anthology a literary work?

Anthologies don't "cites work" they "has part(s)"

Wikidata Divergence[edit | edit source]

HTML[edit | edit source]

HTML (Q95) instance of (P1) programming language (Q7004)

Wikidata has HTML as a markup language which is a data description language which they specify as being opposite of a programming language.

The property programmed in requires items of type programming language or application programming interface. HTML is also a web API which is a subclass of application programming interface so it is allowed to be used with the programmed in property despite Wikidata specifically saying HTML is the opposite of a programming language.

This is the only case where we have a "programming language" that is not a "programming language." We want HTML to show up in our interfaces when users look for programming language items. The complexity is not worth it for us to distinguish between markup languages and programming languages. Thus we say that HTML is a programming language, even though Wikidata does not.

-==== Problem ====
-For critical writings, we have a bunch of "types" (i.e. {{P|1}} items) that came from the ELMCIP Publication Type. For creative works we only have a few.
-For creative works, ''all'' items are {{P|1}} {{Q|804}}. Any other {{P|1}} claims are added as an addition. For critical writings, they are only {{P|1}} their Publication Type. There is nothing linking them together.
-We have a few options with downsides for each:
-# Apply a standard {{P|1}} statement to ''all'' critical writings.
-#; Use [https://www.wikidata.org/wiki/Q55915575 scholarly work (wikidata:Q55915575)]
-#* Problem is that we would be assigning Wikidata items where they are not assigned in Wikidata
-#; Create our own item like "critical writing"
-#* Want to avoid custom items that aren't linked to Wikidata
-# Create our own property like "Work Type"
-#* Want to avoid custom properties that aren't linked to Wikidata
-# Subclass critical writings with an item like "scholarly work" or a custom item like "critical writing"
-#* Can't browse all critical writings. Have to use the Query Service.
-# Track creative work instance types and critical writing instance types outside of the Wikibase (i.e. maintain a private list of what is what)
-#* Our dataset can't be as easily reproduced by others
