- Map all source values directly to standard concept_ids. Store these mappings in the SOURCE_TO_CONCEPT_MAP table.
- If the source code is not mappable to a vocabulary term, the source_concept_id field is set to 0
When processing your data where source value is a reference to a coding scheme contained within the Standardized Vocabularies:
- Map all your source values to the corresponding concept_ids in the source vocabulary. Store the result in the source_concept_id field.
- If the source code follows the same formatting as the distributed vocabulary, the mapping can be directly obtained from the CONCEPT table using the CONCEPT_CODE field.
- If the source code uses alternative formatting (ex. format has removed decimal point from ICD-9 codes), you will need to perform the formatting transformation within the ETL. In this case, you may wish to store the mappings from original codes to source concept ids in the SOURCE_TO_CONCEPT_MAP table.
