Carrot Mapper

Carrot Mapper is a webapp which allows the user to use the metadata (as output by WhiteRabbit) from a dataset to produce mapping rules to the OMOP standard, in the JSON format. These can be ingested by Carrot Transform to perform the mapping of the contents of the dataset to OMOP.

Carrot Mapper provides automated mapping from a selection of vocabularies, reuse of mapping rules across datasets, and manual mapping rule generation.

Carrot Mapper also provides a number of helpful features to support and encourage standardised mappings across datasets.

Carrot Mapper is built using Python, Django and NextJS, with a PostgreSQL database, and is hosted in Azure using Azure App Services, Azure Database for PostgreSQL, and Azure Functions.
