Grahame,

A few comments:

[1] curl -I http://hl7-fhir.github.io/fhir.ttl  -- returns Content-Type: 
application/octet-stream instead of Content-Type: text/turtle

[2] curl -I http://hl7-fhir.github.io/fhir.rdf.xml -- returns 
Content-Type: text/xml instead of Content-Type: application/rdf+xml

Correcting the issues above enables usability with existing Linked Open 
Data tools. For instance, I should be able to browse the data you've 
published at the aforementioned document locations, using existing 
Linked Open Data browsers.

Note, I am note worried about Linked Open Data publication from your 
location, I am simply concerned about document content-type indication 
accuracy.
