The following data types that are not currently included in [[ https://github.com/wikimedia/mediawiki-event-schemas/blob/master/jsonschema/mediawiki/revision/create/1.yaml | mediawiki.revision-create ]] were identified by the team as being useful for ERI purposes. They should be added to ReviewStream:
**Metadata about edits**
- Change tags*
- Size of edit
**Metadata about pages**
- Page views [someone said lego was working on an extension to make this easier]
- Edit protection level (e.g. full protection, semi-protection/autoconfirmed users only, no protection)
- Whether the page is a disambiguation page.
**Metadata about users**
- Number of edits
- What user-groups the user is in (e.g. sysop/administrator, patroller, researcher, rollbacker, autoconfirmed).
- Registration date
*Regarding change tags, there are [[ https://en.wikipedia.org/wiki/Special:Tags | about 120 in en.wiki. ]] But I believe tags vary in different wikis. Is there a way to include them all, or do they have to be added wiki by wiki? There is a [[ https://phabricator.wikimedia.org/T24509 | related task about adding tags to RCStream ]].
