RE: Proposed RDF FHIR syntax feedback

Marc,
There is probably some right balance between having the prefix state the namespace or to have the dot notation as in FHIR.
However there are some base FHIR URIs which might deserve prefixes:

http://hl7.org/fhir/structuredefinition/ (when the FHIR website moves there)
http://hl7.org/fhir/vs/ which supports the valuesets

There may be more in FHIR that I have not yet discovered and Lloyd will know what they are.

Regards,

Tony

I fully support having a single "fhir" prefix. This will help at 'FHIR ontology' development level with making reusable predicates.
Also at instance level it would help to include something that identifies order for array elements

Several comments:
1. I'm not clear on the benefit of defining prefixes for every resource and type.  The alternative is a single "fhir" prefix
2. We need to include something in the instances that identifies order for array elements
3. Do we need to declare type everywhere?  Quite often, the type can be inferred from the context and the property name by consulting the resource/data type definition ontology.  Explicitly listing types everywhere adds verbosity to the instances and also adds complexity to the conversion process
4. Not sure why we have nodes underneath "div".  Can't we just have "div" be of type string for our purposes?

Additional things to add to our example:
- a nested structure (e.g. DiagnosticReport.image)
- a reference to an external resource (outside the bundle) and reference to something within the bundle (local, full reference-version independent, full reference-version dependent)
- a codeable concept with multiple codings
- a coding with version declared
- a coding with valueset declared
- a coding with code but no system
- an instance of identifier
- an "id" attribute on an element
- a reference to the same id attribute (likely from an extension)
- an extension with a simple type
- an extension with a complex type
- an extension that repeats and has multiple values
- an element that is an instance a choice (element name is something[x])
- a reference to Questionnaire or one of the other resources that has recursion.  Could just be added to the bundle
