What happens in Wikibase when you make a new Item?

A recent Wikibase email list post on the topic of Wikibase and bulk imports caused me to write up a mostly human readable version of what happens, in what order, and when, for Wikibase action API edits, for the specific case of item creation.

There are a fair few areas that could be improved and optimized for a bulk import use case in the existing APIs and code. Some of which are actively being worked on today (T285987). Some of which are on the roadmap, such as the new REST APIs for Wikibase. And others which are out there, waiting to be considered.

This post is is written looking at Wikibase and MediaWiki 1.36 with links to Github for code references. Same areas may be glossed over or even slightly inaccurate, so take everything here with a pinch of salt.

Reach out to me on Twitter if you have questions or fancy another deep dive.

If you’re working with legacy code, chances are you’ve inherited some technical debt. Infact, if you’re working with code, chances you’re already surrounded by technical debt of varying sizes, at least by some measures.

Some believe that technical debt is something to be avoided, and that technical debt that exists is a dirty secret that should be hidden. The reality is that technical debt is a fact of life when code iteratively changes to deliver product solutions.

Striving for programming perfection is great in principle, but ultimately code is meant to deliver features, and there is always a good, better and best approach, with many other variations in-between.

Over the last year at Wikimedia Deutschland we have worked on refining how we record, triage, prioritize and tackle technical debt within the Wikidata and Wikibase product family.

There are many thoughts out there about how to track, tackle, and prioritize technical debt. This post is meant to represent the current status of the Wikidata / Wikibase team. Hopefully you find this useful.
