# Introduction
Introducing v2 object metadata service create one handler v2, not
overkilling the flatObjectMetadata validation for the moment that will
require sequential validation for the import in order to handle
relations and morph relations
# Introduction
Following https://github.com/twentyhq/twenty/pull/13420
What has been done:
- `CreateFieldInput` transpilation to `FlatFieldMetadata`
- `FlatFieldMetadata` validator service
- A lof of transpilation utils from `input` to `flatObject` or
`flatField`
- Created dedicated v2 api metadata services
- Introducing `inferDeletionFromMissingObjectFieldIndex` in the builder,
to avoid diffing every object and field of the current workspace we
allow only generating create/update migration operations, usefull when
passing by the api metadata
## We still need to in another PR:
- Implement a strong unit test coverage and critical functions and
services
- Finalize flat field metadata validation exception for `options`
`defaultValue` `settings` and `relations`
- Finalize `flatObjectMetadata` validation and v2 service refactor
- Plug the new service when feature flag is enabled
