The initial Edit Check the Editing Team is implementing is being designed to increase the likelihood that people will accompany the new content they are adding with a reference.
To evaluate the extent to which Edit Check is being successful in causing people to do the above, we will need a way to count, in aggregate/at-scale:
1. The edits people make that involve them adding new content to the wikis (T333714) //and//
2. Whether these edits do or do not include references (this ticket)
=== Stories
- **As a Data Scientist** motivated to evaluate the impact of Edit Check, I need to be able to differentiate between edits in which people added references from edits in which people have //not// added references, so that I can evaluate Edit Check's impact on peoples' likelihood to accompany the new content they are adding with a reference
- **As a volunteer** motivated to assess the impact the initial Edit Check is having on peoples' likelihood to include references when adding new content, I need to be differentiate between edits in which people added new content that are accompanied by a reference from edits in which people added new content that are //NOT// accompanied by a reference, so that I can decide whether it's worth proposing changes to the heuristic that will have been initially defined in T324730
=== Requirements
1. A **hidden** change tag is appended/associated with all edits made using the **visual editor** to pages in the **main namespace** that involve an edit where people add a net new reference.
-- //Where "net new reference" in this context means that the reference had not been previously included within the document they are editing.//
2. The hidden change tag "1." described is called `editcheck-newreference`
=== Open questions
- [x] 1. What – if anything – beyond the software detecting that someone added a //new// reference in the edit they are saving should cause this new edit tag to be added to said edit? //E.g. does the edit *also* need to involve someone adding new content?//
-- The tag this ticket introduces will be narrowly scoped to whether an edit involved someone adding a "net new" reference or not. A separate tag (T333714) will do the work of identifying edits that involve new content being added.
- [x] 2. Will the edit tag this task is "asking" for be applied regardless of the editing interface someone used to make said edit? //See T325713#8718860.//
-- Per what was discussed during the team meeting the Editing Team had on 7 June (see outcomes in T333714#8920087), to start, this tag will only included edits made with the visual editor. As a result, the tag this ticket introduces will be hidden as is specified in the `Requirements` section above.
