Wikidata:Schema proposals/written work

Name	written work
Description	Schema for all items on Wikidata which are classified as some kind of "written work". The required properties should be very broad to make sure it matches the most important statements for a wide range of items. NOTE: There is an existing schema for written work (E35), but we may need a more simple version for the general use suggested. See discussion below.

Who	Step	Description	Progress	Instructions
Community	1	Create proposal page	Done
	2	Community topic groups notification		Try and involve as many people as possible in the discussion, especially those with specific knowledge about the subject area. A good place to start is posting messages to relevant Wiki Projects on Wikidata and Wikipedia with a request for feedback (make sure you include a link to this page). You can also post messages on Wikidata:Project chat for general feedback and help finding other editors with relevant subject knowledge.
	3	Community discussion		Add new topics as required to the Discussion section below. The aim is to reach a consensus on the correct structure for the proposed schema, and present this in the Proposed model section below.
	4	Proposed schema ready		Once the Proposed model section is complete, change the status at top of page to "Ready"
Technical	5	Create schema		The new Wikidata Schema is created at this stage by a technical editor, using the proposed model on this page to define the structure. The status should be changed to "done", and "schema_id" added to the template so that a link is shown to the new schema
	6	Add link to this proposal on talk page of new Wikidata Shema		This ensures the proposal discussion can always be found easily, as all future discussion will take place on the talk page of the new Wikidata Schema page.
Community	7	Community topic groups notification		Let users involved in the discussion know the new schema is ready.

Discussion

External schemas	Written work (E35) - A very comprehensive schema, which also includes constraints on connected items (e.g. the publisher specified must have "instance of" = "publisher")
External databases

Does existing E35 schema cover all the use cases required?

The E35 schema for written work is extremely detailed. It includes constraints on connected items as well as the actual written work itself (e.g. the publisher, editions of the work, etc).

This is very useful, but it might be far too comprehensive for many use cases as a large number of items will "fail" when checked against the schema.

Do we need a new schema that is less detailed but easier to use? NavinoEvans (talk) 15:20, 29 April 2021 (UTC)

How many items does this apply to?

Technically it should apply to all "instance of" = "written work", including subclasses (e.g. "book", "report", "blog post" etc) which is around 48 Million items.

There are around 70,000 direct instances written work (see https://sqid.toolforge.org/#/view?id=Q47461344 for these stats). NavinoEvans (talk) 15:20, 29 April 2021 (UTC)

Can we get a nice visualisation of the existing schema for comparison?

It's really hard for anyone who doesn't know the ShEx language to understand the existing E35 schema. We should create a visual version below for discussion.

The model from WikiProject Books has now been pasted in below. This appears to be what the existing E35 schema has used. NavinoEvans (talk) 14:53, 14 May 2021 (UTC)

Proposed model

The model below is taken from WikiProject Books, where they have agreed the properties to use based on discussions within the project.
