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-CDM 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 React, with a PostgreSQL database, and is hosted in Azure using Azure App Services, Azure Database for PostgreSQL, and Azure Functions.
