Mirador 4 planning

[cbeer]

This is a start of a list of ideas + issues that may require a new major release of Mirador.

Technical architecture

React is moving (has moved?) away from Component classes towards functions and hooks. We might take this opportunity to align with upstream conventions:

• Figure out how to test, ignore, or replace containers #2047 : Figure out how to test, ignore, or replace containers
• Prefer Stateless Functions #1858 : Prefer Stateless Functions
• Mirador (for React reuse) distribution should not bundle React #2003 : Can we unbundle React?

UI/UX

Material UI 5.x is on the horizon. It's unclear if it will be a major breaking change, or something we can support in a minor release:

• Test using https://github.com/mui-org/material-ui/releases/tag/v5.0.0-alpha.4 #3221 : Test Material UI 5.alpha

Plugin system

• Support componentless plugins #3160 "Componentless" plugins
• Plugin implementation doesn't work as intended #2099 Make the plugin system easier to implement
• Provide an event subscription system for external API consumption #2084 Provide non-redux "events"

Revisit/review

These tickets have some ideas for potential work that wasn't pursued in Mirador 3 development.

#1693 : Define/revisit Mirador API Requirements
#2200 : Refactor the Mirador entry point
#1991 : M3 non-functional requirements, concerns and issues
#2604 : Group components into folders
#1863 + #2951 : Naming conventions
#3258 : Validate used attributes
#2051 + #1628 : Redux payload format
#1808 : Generic fetching actions
#1749 : Improve (and make consistent) API error handling

Hi,
Is there an update on when version 4 is planned for release?

The Scrum team I'm the product owner for at the Swedish National Archive is currently investigating options for IIIF Viewers with a focus on search and display of OCR/HTR-texts similar to Minutes of the Federal Council (1848-1972) - Search (admin.ch)

We're in doubt as to whether to focus our evaluation on the latest stable release, 3.3, or whether to work against the main branch with the hope it'll fairly soon become the 4.0-release.

Best regards,
David
