mchades opened a new pull request, #13571:
URL: https://github.com/apache/gravitino/pull/13571
### What changes were proposed in this pull request?
- Add REST APIs to import and export Semantic Models as standalone Apache
Ossie YAML or JSON documents.
- Convert Ossie fields to the native Semantic Model definition and preserve
Gravitino properties through a reserved custom extension.
- Add the optional `ossie-version` property with the default value
`0.2.0.dev0`, while preserving any non-blank version specified by users.
- Validate document structure, source identifier shape, dialects, property
values, and conversion errors.
### Why are the changes needed?
This enables Semantic Models to be exchanged with Ossie-compatible tools
while reusing the existing Core create and load operations.
Fix: #13540
### Does this PR introduce _any_ user-facing change?
Yes.
- Adds `POST .../semantic-models/ossie` for importing Ossie documents.
- Adds `GET .../semantic-models/{semanticModel}/ossie?format=yaml|json` for
exporting Ossie documents.
- Adds the `ossie-version` Semantic Model property.
- Ossie sources remain `catalog.schema.entity`; the metalake continues to
come from the REST path.
### How was this patch tested?
- `./gradlew spotlessApply`
- Focused Core converter, property metadata, dispatcher, and Server REST
tests
- `./gradlew :api:check :core:check :server:check -PskipITs`
- `git diff --check`
Draft follow-up:
- Add OpenAPI documentation after #12627 introduces the base Semantic Model
OpenAPI specification.
