# Introduction
Preparing view-filter and view-group introduction in v2 core engine
Moving view from `core-modules` to `metadata-modules`
## What happened
### Created dedicated modules for each view entity:
- ViewFieldModule
- ViewFilterModule
- ViewFilterGroupModule
- ViewGroupModule
- ViewSortModule
### Each module is now completely independent with its own:
- Controller
- Resolver
- Service
- Entity
### Created dedicated abstraction metadata module folder for:
- flat-view-field
- flat-view
### Dependencies
- Eleminated circular dep on ViewModule to all others ones
- Granular import not importing the whole viewModule anymore everywhere

There's a huge test bundle in the latest shard that we could split up
## Notes
- Set as failing morph relation field rename as for the moment we do not
handle relation field mutation
- fixed the object update and creation validation adding label
identifier field metadata id checks
- and more
Some integrations tests are still on the v1 ( they have before and after
all disabling and re-enabling the flat ) but mainly we now have more
coverage on the v2 than the v1.
Mainly related records, uniqueness have to be migrated the v2 and so
tests too
