When will Wikidata have its first lame edit war because two sister projects disagree on how to structure their shared data?

Interwiki fixes

My multi-cultural identity means that I often find myself fixing correspondences between similar concepts in different languages. Below are groups of easily confused items that I've tried to fix:

• Eggy rolled-up food
  • spring roll (Q715525) (春卷)
  • biscuit roll (Q4102828) (蛋卷)
  • Swiss roll (Q320657) (Swiss roll)
  • egg roll (Q4103048) (蛋皮卷)

• Highly involved parents
  • monster parents (Q20983091) (Japanese-origin term)
  • helicopter parent (Q1352982) (USA-origin term)

• posthumous (Q1395509) - three-way merge of two European and one East Asian concepts, all referring to the act of conferring honour after someone's death

• saltwater fish (Q5364423) - two-way merge between saltwater fish in European language and saltwater fish in Asian languages

Property migration tools

My greatest (and perhaps most controversial) contribution to Wikidata so far has been the creation of two pywikibot scripts that perform property+qualifier migration semi-automatically. This allowed the deprecation of P794 ("as" - deprecated because it is untranslatable to non-European languages), the Pokedex merge and a few other property/qualifier deprecation batch jobs.

• /SPARQL
• /Property migration tool (Migrate P1/Q2 to P1/Q3)
• /Property migration tool 2 (Migrate P1/Q2 to P3/Q4 with quantity → string datatype change)
• Property migration tool 3 (Migrate P1 to P3, preserving all qualifiers, references, and rank)
• Property migration tool 4 (e.g. [1])
• /P794 migration log
• /P31 qualifier migration log

Wikidata talks

I have given a few Wikidata talks at Wikimedia conferences, and some of them have dedicated wiki-pages or slide-decks:

• Wikidata and infoboxes panel discussion, Wikimania 2017
• "Wikidata is a language", Wikimedia UK AGM 2018
• Wikidata infoboxes talk, Wikimania 2019
