6.0.0-alpha1

Introducing Firely SDK 6

SDK 6.0 is a major release putting the POCOs more and more at the center of our development efforts. We are extending the POCOs to be more flexible and the interface between POCOs and the FhirPath engine (and validation) to be more performant. This is our plan to make this a reality:

• Add "overflow" to POCOs, so they can contain data elements that are unknown or incorrect. Create the notion of a "DynamicResource" that can represent any unknown resource.
• Change our parser so they can take advantage of this overflow.
• Make sure any ITypedElement can be converted to a POCO, so you are basically getting the flexibility you have with ITypedElement, but then working with POCOs.
• Make the POCOs implement ITypedElement and ISourceNode so existing code can still use these concepts, but with POCOs as an underlying transport.
• Change the FhirPath engine and the validator to work against POCOs instead of ITypedElement.

This will almost completely remove the dependency on the ITypedElement stack from our POCOs and FP/validation, resulting in more performance and less memory use. At the same time we strive to keep the current ITypedElement-based code working for the forseeable future.

This early alpha is really an internal release, so unfortunately there is no documentation available on the new features, and it is likely the new APIs will change based on the feedback we get from testing this alpha in our Firely products. That said, we expect this 6.0 to be mostly backwards-compatible, so you CAN definitely try to update to this release and see if your software still works. We'd love to learn about any regressions you might encounter.
