Main usage - instanceOf, 201 832 items.

Some misuses can be noticed even at the first level;

How many instances each of the subclasses have (706 939 overall): SparQL

Almost 3000 subclasses is huge, even though there are also a duplicating 'literary genre' and 'literary form' hierarchies. Seems like this item has no well-defined meaning;

After removing song (Q7366) subtree it lost 451 nodes, from 2929 to 2478.

Rating of properties among direct instances: SparQL
These items are non-direct instances of literary work: SparQL (308 results)

Probably significant amount of them misused instanceOf property, because it's only 0,1% comparing to direct instances of literary work (Q7725634);

Instances which also have instances themself: SparQL.

fairy tale (Q699)

• Is used as a value of this properties: Query (22 results)

It seems to be a confusion of how to use it - as an instanceOf (2468) or as a genre (1033).

• Full subclasses graph: SparQL

There are subclasses for russian and japanese fairy tales, but not for 200 other countries. Speaking of assigning properties for actual fairy tales, I believe these subclasses shouldn't be used, because there is a country of origin (P495) property.

• There are none non-direct instances of it, which is good: Query (1 results)
• There are 106 instances of subclasses of fairy tale (Q699): Query (106 results)

Half of them are instances of Rondalla (Q11946197), which pretty much looks like synonym for a fairy tales in catalanian language.

• To find all fairy tales on wikidata you should look for all direct instances of fairy tale (Q699) + all instances of any of it's subclasses + all literary works with a genre = fairy tale, which is counter-intuitive and simply cannot be done because of timeouts: Query (timeouts)
• Different from folk tale (Q1221280) which can't have an author.
• Also there is a literary fairy tale (Q24723) folktale type (Q47451145) traditional story (Q7832362).

encyclopedia (Q5292)

• Nobody knows how to properly use this item: there are 1142 direct instances and 743 items with genre (P136) = encyclopedia (Q5292);

Direct instances: Query (1142 results);

Items with genre = encyclopedia: Query (743 results);

These sets almost doesn't overlap.

• Encyclopedia is already a subclass of a written work (Q47461344) and fits nicely in here under 'reference work': Query
• This is what people usually choose to use as 'instance of' for encyclopedias: Query (109 results);

Top-used value is encyclopedia (Q5292) which is natural (1149);

Second usage is written work (Q47461344) which is also correct, but a broader category (308);

Third is literary work (Q7725634) which is probably wrong, because this item is used for 'creative works created with aesthetic or recreative purposes' (248).

• Right now every encyclopedia in Wikidata has an implicit literary genre, but cannot be considered as a literature work, which is unnatural.
