Tools to transform CORE rule structures

Implement alternative transformers

In order to create a transformer provider for a different type of storage, implement the Transformer interface. Some provider implementations are already provided:

• CosmosdbTransformer for ms cosmosdb storage
• JSONTransformer for simple json filesystem storage
• YAMLTransformer for simple yaml filesystem storage

Create transformers

CosmosdbTransformer

from transformer.transformer_cosmosdb import CosmosdbTransformer
prod_transformer = CosmosdbTransformer(
    getenv("PROD_COSMOS_URL"),
    getenv("PROD_COSMOS_KEY"),
    getenv("PROD_COSMOS_DATABASE"),
    getenv("PROD_COSMOS_CONTAINER"),
)

JSON File Transformer

from transformer.transformer_json import JSONTransformer
json_transformer = JSONTransformer(f"{getenv('WORKING_DIR')}/rules")

YAML File Transformer

from transformer.transformer_yaml import YAMLTransformer
yaml_transformer = YAMLTransformer(f"{getenv('WORKING_DIR')}/rules")

Export Rules

prod_transformer.export_json(f"{getenv('WORKING_DIR')}/rules")

Delete and replace rules from one transformer location to another

from transformer.transformer import Transformer
Transformer.replace_rules(
    from_transformer=prod_transformer, to_transformer=dev_transformer
)

Run Transformations

There are sets of transformations available and you can implement your own set of transformations. Some sets provided:

• transformations_misc
• transformations_crog

Run CROG Schema Transformations:

from transformer.transformations_crog import (
    all_transformations,
)
dev_transformer.transform_rules(all_transformations())
