Code Review

This pull request renames the CRUD operations in the MongoDB repository from 'Entity' to 'Metadata' (e.g., CreateMetadata, ReadMetadata) to better reflect their specific purpose. The changes span the repository implementation, the metadata handler, and associated tests. Feedback was provided to update the accompanying function comments to ensure they consistently refer to 'metadata' instead of 'entity' or 'attributes,' maintaining clarity throughout the codebase.

Pull request overview

This PR renames the MongoDB repository CRUD-style methods from *Entity to *Metadata to better reflect that the MongoDB collection is being used for metadata persistence rather than full entity lifecycle management (per Issue #340).

Changes:

• Renamed CreateEntity/ReadEntity/UpdateEntity/DeleteEntity to CreateMetadata/ReadMetadata/UpdateMetadata/DeleteMetadata in the MongoDB repository.
• Updated the Mongo metadata handler to call the renamed repository methods.
• Updated the MongoDB repository tests to use the renamed methods.

• Renaming these methods removes the previous CreateEntity/ReadEntity/UpdateEntity/DeleteEntity APIs, but there are still non-test call sites in the repo that reference the old names (e.g., opengin/core-api/engine/graph_metadata_manager.go and opengin/core-api/cmd/server/service.go). As-is, the core-api build will fail due to missing methods. Either update all remaining call sites in this PR or keep backwards-compatible wrappers (deprecated) that forward the old method names to the new *Metadata methods.

func (repo *MongoRepository) CreateMetadata(ctx context.Context, entity *pb.Entity) (*mongo.InsertOneResult, error) {

• The test name/commentary in this section still refers to deleting an “entity”, but the repository call is now DeleteMetadata and is specifically deleting the metadata document. Consider updating the wording to avoid implying the underlying graph/entity is deleted.

	// Create entity
	_, err = testRepo.CreateMetadata(testCtx, entity)
	assert.NoError(t, err)

	// Delete entity
	result, err := testRepo.DeleteMetadata(testCtx, entityID)
	assert.NoError(t, err)
	assert.Equal(t, int64(1), result.DeletedCount)

	// Verify entity is deleted
	_, err = testRepo.ReadMetadata(testCtx, entityID)
	assert.Error(t, err) // Should return an error since entity doesn't exist

• This test now exercises DeleteMetadata/ReadMetadata, but the test name and the doc comment block above still reference "DeleteEntity" and deleting an "entity". Please update the test name and the doc comment so they match the renamed API and describe that only metadata is being deleted from MongoDB.

	// Delete metadata
	result, err := testRepo.DeleteMetadata(testCtx, entityID)
	assert.NoError(t, err)
	assert.Equal(t, int64(1), result.DeletedCount)

	// Verify metadata is deleted
	_, err = testRepo.ReadMetadata(testCtx, entityID)
	assert.Error(t, err) // Should return an error since metadata doesn't exist

Hi @prdai. One of your workflows is failing due to a deprecated key in the workflow file. I have now fixed that and merged it into main. Please rebase your code from main, I will then rerun your workflows.

hi @zaeema-n, i rebased with upstream main, let me know if there is anything else to be done, thanks!

LGTM! Thank you for your contribution @prdai!
