FHIR Tool for requirements capture

I’ve been experimenting with a tool to allow the creation of “models” using some of the underlying capability of FHIR (e.g. FHIR Data Types, Structure Definitions etc). The tool allows you to create models of just about anything, note it’s not a profiling tool (for that I’d recommend Forge).
It’s an early version of the tool and there’s plenty left to do but if anyone has the time to spare (!!) and want to take a look I’d appreciate feedback.

The tool is developed in .NET and is available from dropbox here Dropbox - Flogical_1_0_0_2.zip - Simplify your life

If you want some example models to play around with then there are some (created by NEHTA in Australia, using a different tool) here
