TAG META.SECURITY HAPI FHIR

[Michele S]

When using a HAPI FHIR server, I noticed that when performing a PUT operation on a resource and updating the meta.security tag, the information is appended instead of being replaced.

According to the FHIR R4 standard, a PUT operation should replace the entire resource, including the meta fields.
How can I solve this problem so that the operation updates (replaces) the tag instead of appending it?

Thanks!

Hi Michele,

FYI: The standard actually recommends the behaviour you're seeing. Tags and security labels work differently from the rest of the spec. See here: http://hl7.org/fhir/resource.html#tag-updates

> When a resource is updated (e.g. on the RESTful interface), servers generally follow this pattern:

> (...)

> Merge existing and new security labels

This isn't a hard SHALL requirement though, so servers don't have to work this way. You can change the "Tag Storage Mode" from the default of VERSIONED to a mode called INLINE which makes tag storage work as a snapshot just like the rest of the resource. This is available on the JpaStorageSettings bean - it looks like this hasn't yet been exposed as a setting on the JPA Starter project yet, so this would need to be added.

Cheers,

James
