UIApi / Loading Data / Data Ops

[elbakerino]

Data connections which work in a consistent way can be fully automated with further logic, e.g. especially those which are abstractable with languages/tech like OpenAPI, HTTPAPI, JSON API, Mongo/MangoQuery, Google Firestore Data Model etc.

Development of more complex data handling UIs can be sped up with existing plugins and adapters.

Especially features for schema-driven editors like the following should be thought about during dev:

• block-based (endless nestable) data UIs
• collection management (lists, tables etc.)
• publish only systems
• crud working pages
• app and in-data navigation
• mixing input data with different relation management systems

This would require new plugins and widgets, maybe even new validators.

Development should be done after #49 - relying on the than available validation system.

This is the data-side which complements #45

hyper-schema is in hiatus and thus won't be in scope atm.
