## Summary The usage of the underscore character as a prefix for system fields to makes it impossible to store native JSON-Fhir Documents in CouchDb. In [FHIR ](https://hl7.org/fhir/) someone decided to use the "_" as a prefix for field-extensions. ```json "birthDate" : "1974-12-25", "_birthDate" : { "extension" : [{ "url" : "http://hl7.org/fhir/StructureDefinition/patient-birthTime";, "valueDateTime" : "1974-12-25T14:35:45-05:00" }] }, ``` ## Desired Behaviour It should be possible to store any valid JSON Object in CouchDb ## Possible Solution Configurable "Special Character(s)" to allow JSON fieldnames beginning with underscore "_" . So each user can decide what chars to avoid in it's datadefinitions. Or perhaps a kind of internal masking for such keys ## Additional context It would be great to store JSON-Fhir objects natively in CouchDb because I think it could be the coolest thinkable storage engine for it -- This is an automated message from the Apache Git Service.
