Hi Gerard, RDF on its own certainly will *not* create semantic interoperability of healthcare information. It is only a first step, which allows the semantic to be expressed in a common language. I agree that the whole process of achieving semantic interoperability is much more involved. The Yosemite Project describes a roadmap to get there: http://yosemiteproject.org/ Thanks, David Booth On 10/31/2015 05:13 AM, "Gerard Freriks (privé)" wrote: > Dear David, > > With interest I have attended two Telcon meetings. > And I have read some slide sets from presentations. > > Some remarks I want to make: > - RDF (and related formats) could be used.
