Redmatch is a tool that allows transforming REDCap forms into FHIR resources, using a domain specific language to write transformation rules.

This tool is targeted at domain experts that know about FHIR but don’t necessarily have programming language skills. The rules engine implements a domain specific language that allows defining the transformation rules without the need to write any code.

Redmatch is experimental software. Use it at your own risk! Take a look at the full description of the current set of known issues.


  • Domain specific language to define transformations between REDCap and FHIR
  • Integration with REDCap through its API
  • Support to define mappings to standardised terminologies
  • Export to FHIR JSON-LD format, compatible with Pathling
