This is a main ticket tracking WMDE efforts on decoupling Wikibase Repository and Client components/applications in Summer 2020.

Expected outcome:

• “Repo” and “Client” components are fully and clearly separated from each other
• Long-term strategy outlined for organizing the “shared” logic
• Long-term strategy outlined for organizing the “Repo” front end logic

Additional requirements related to migrating Wikibase extensions to use Extension Registration

• WikibaseRepo uses Extension Registration
• WikibaseClient uses Extension Registration
