Presenting NeoEHR

Borut Jures

I'll list what I have done so far in case it helps to prepare questions:

• I started with a BMM parser and converter to in-memory representation of the BMM files.

• I used the BMM files to generate classes for AM and RM types.

• I generated UML diagrams for the AM and RM types (https://neoehr.com/openehr/uml ).

• I wrote a OPT2 to JSON converter since Pieter was busy and didn't want to add the required small fixes to his to-do list.

• The generated AM types have a fromJson() method that can read the OPT2 JSON. At the same time it validates that it conforms to the correct format (see file AM206.zip).

• When the OPT2 is loaded into memory as AM classes I build in-memory model of the OPT.

• From the in-memory OPT model I generate OO representation of the OPT (see file VitalSignsSDK.zip).

• The generated OPT models should be structurally similar to the UI representation of the OPT (I'm guessing). I'll work on trying to generate a forms app next.

• In-memory model of the OPT has a "walker" that calls a "writer" methods. The walker part is always the same (SDK or forms). For the forms I have to "only" write a different writer. This "only" is probably a bigger task that all of the above.

You have done the same with your code bases. I haven't done anything new. Maybe the only difference is that all the code can be run on a client side (web, iOS, Android) or server side.
This allows for scenarios such as:

• Reading OPT2 (in ADL) on a client.

• Validating OPT2 on a client before generating JSON for the CDR.

• Validating received JSON on the server (I have to add invariants to the generated code).

• Automated conformance checking?
