The establishment of inter-organizational in-teroperability solutions requires agreements on many levels, and open vertical standards such as HL7 combined with horizontal industry standards provide solutions to many of these levels. SOA based interfaces using vertical industry standards and models are good starting points, but they must be further refined to guarantee interopera-bility and fit for local requirements.
