If every FHIR element was mapped to a snomed term, then you could
represent that in RDF no problems.
However the problem with this is that we already have a slot for
mapping an element to it's snomed code, but there are hardly any
snomed codes that are appropriate.
Ihtsdo are planning to have their own go at flapping these next year,
I imagine that they'll have to create a lot of codes to are it useful.

Hi Vipul,
To me, your first two points go together. The only reason to do
an RDF representation is to support implementations that want to
make use of semantic web technologies for inference purposes.
I wouldn't describe either as requirements for the syntax though.
A requirement would be a particular type of inference that we
wanted to enable (or wanted to optimize for).
In terms of your third point, there's two different ways we could
interpret this. One would be to say that we'll convert both FHIR
structures and FHIR vocabulary into RDF and include the linkage
between them as part of the class model. I'm definitely on-side
with that. The second way would be to say that we'll be able to
easily integrate existing ontologies from other code systems such
as SNOMED with the FHIR structure ontology. I think that's a much
tougher thing to do, though it may be possible in some cases. I'd
like to treat it as a secondary objective, but am ok with having
it on the table.
(Feel free to add your thoughts to the wiki page.)

Subgroup / W3C HCLS COI call -- Review of FHIR ontology
approaches (cont.)____
__ __
I think we need to define our objectives for the RDF
representation. Mine are as follows:____
__ __
1. It must be possible to round-trip from XML/JSON through RDF
representation____
* This includes retaining information about order of repeating
elements____
* Needs to allow for extensions where-ever they can appear,
including simple types (date, boolean, etc.)____
2. We want to be able to represent instances as RDF and
Profiles as OWL/RDFS____
3. Syntax needs to be "safe" when dealing with modifier
extensions____
4. Syntax should support vocabulary bindings to code, Coding
and CodeableConcept - including dealing with extensible value
sets and multi-code system value sets____
5. Syntax should enforce constraints that are representable in
RDF (i.e. schema constraints, regular expressions, etc.)____
6. In the RDFS/OWL, should expose at least minimal annotation
information for display____

[31]http://www.w3.org/2014/Talks/1125-fhir-rdf-egp/ FHIR-RDF
[31] http://www.w3.org/2014/Talks/1125-fhir-rdf-egp/
Eric: Our goal was to let anything in FHIR XML be translated
into RDF.
... We wrote something that read the XML definition files and
produced something that maps the XML to RDF.
... Python code reads the json definition files and spits out
XML, being the parts that we need of the FHIR spec.
... "subs" is what is allowed inside a FHIR resource.
... effectively the attributes of a resource.
... Then we embedded that in an XSLT script, and hand edited
the foot of it.
... The stuff we wrote into the footer of the XSLT says that
for a particular construct in the XML instance data, there's
special handling, such as URLs for identifiers.
David: How does the fact that it is an atom feed affect the
interpretatinon of the XML?
Eric: It leaves some other graph stuff superimposed on it.
Marc: Re datatypes, you used FHIR value, but the value itself
looks like it is a string.
... If it is a string, then reasoners cannot do much with it.
Eric: Datatype values are showing up as literals.
Marc: Another is that a date is just a string, not an xsd:date.
... On slide 2
Eric: Ideally it should have the datatype stuck on the end of
it. There's a tension between having the datatype on the
fhir:value and having it on a blank node.
... The natural RDF-ish way to do it would be using
xsd:datetime.
... Need to decide which of these ways will be most palatable
to RDF folks versus native FHIR folks.
... Sometimes these things are not just datetimes in FHIR. Need
to make it as simple as possible and no simpler.
Guoqian: Is a different URI being used for the namespaces? Will
it cause problems when you use SPARQL across different models?
Eric: I tested some of this. I stuck a bunch of these
namespaces together, and I believe we've addressed your
concern.
David: Is the datatype issue due to the fact that datatypes are
extensible in FHIR?
Eric: Maybe. RDF needs to be monotonic.
Paul: Modifying extensions can appear only in the roots of
classes (considering the complex type as a class)
Eric: The XSLT footer has the custom code for extensions.
Paul: We did that to limit what you need to examine, to find
out if there is a modifying extension.
Claude: I think you can have modifying extensions on the root
type and anything that is defined from the root type.
ISSUE: FHIR Modifying extensions and monotonicity
<trackbot> Created ISSUE-1 - Fhir modifying extensions and
monotonicity. Please complete additional details at
<[32]http://www.w3.org/2014/HCLS/track/issues/1/edit>.
[32] http://www.w3.org/2014/HCLS/track/issues/1/edit
Eric: Example here may not be up to date. Anyone know?
Paul: the dev site has DSTU 2.
Eric: Another script generates the ShEx definitions from the
FHIR spec.
... and the ShEx is used to generate FHIR XML back again from
FHIR RDF.
... Slide 7 is showing how to take C-CDA in RDF and producing
FHIR RDF.
Guoqian: The result prefix is fhir but should be patient.
Eric: Yes, you're right. That can be fixed in the ShEx.
Tony: Sort of verbatim translation. The difference is maybe
target audience style -- a style that is good for the general
tools used in RDF. Only difference is the end style of RDF.
... Establishing closure between FHIR ontology and SNOMED-CT
would need to happen. Main difference is in the final RDF
style.
<pknapp> Zakim: Have to leave for another meeting, thx, great
work.
Eric: Will need to need to be a balance.
... Once we have transliterated, what we map to our dream
ontology. May want to balance how much is wedged into the XSLT
and how much into the interpretive dance later.
Claude: Might want a low level FHIR ont and a higher level FHIR
ont both.
David: I kind of like the auto-generated aspect of this
approach.
