Benefits of a combined SOA & IHE approach
- If PIX and PDQ are read as profiles, there are 5 pages of functional description, very high level, and 95 pages giving every detail of every transaction. HSSP spends 95 pages on functional description and operation semantics, and 5 pages on what could happen on the wire – the latter may be barely described. Would PIX/PDQ V2 and V3 be identical (in terms of operation semantics)? Probably, however, the service is never described in IHE.
- The point of this paper is to bring these two efforts together.
- Facilitating responding to changes in business requirements
- IHE takes what is constant out of the equation
- Adding, replacing, reconfiguring services
- SOA can include interoperability elements in its approach but does not deliver interoperability
- SOA is an implementation approach
