AccessPolicy V2​

We have added support for a new version of the AccessPolicy resource. This version allows for more fine-grained control over access to resources. We use a rule engine based on XACML to evaluate whether a user can perform a given request. This is evaluated using fhirpath expressions on the request and the user's claims.

More information can be found in our RFC

General​

FHIRPath​

We've rewritten our FHIRPath parser to be more performant. Currently, we've seen a roughly 60% improvement in parsing time. This will allow us to index resources faster and improve the performance of our FHIRPath queries.

Expression component​

We've added a new component to our component library that allows you to view FHIRPath expressions. We have written a custom codemirror mode to highlight and format FHIRPath expressions.

Meta values​

We've altered the way we pull type information about resources. We've created a pre-generated hashtable of type information per resource and use this to validate resources and for type information in our FHIRPath queries.
