Using arc42

Decision Date: End of 2020

Summary: Use the arc42 template (opens new window) to document the architecture of Wikidata/Wikibase.

Details

The arc42 template (opens new window) for documenting architecture was suggested to us by thePHPcc whom we worked with.
We liked the template's structure and we didn't have any alternative templates in mind, so we went with it.
Later we established the systems we want to document are too big and we can benefit from using the template several times throughout the docs. This is why each system (e.g. Wikibase Client, Wikibase Repository) uses its own arc42 template.

The Overview does not have the full arc42 structure on purpose!
It contains only the parts that make sense for providing overview of the Wikidata/Wikibase ecosystem (like Architecture Constraints, Context and Scope, and Glossary).
