The Semantic Dialogues tells the story of how National Networks, a fictional telecommunications service provider, pursued and achieved data interoperability within their SOA. The story begins with an urgent request from Operations for a fix to a problem that's keeping them from billing for new services. Assured that
extensions can be made to the common data model (the SID) for the COTS billing system that's causing the headache, the problem is resolved in short order. The story then goes back a year to a time when the lack of a data interoperability layer made similar problems seem insurmountable and a tiger team is formed to put in place an OSS/BSS architecture that will change the way the CSP does business.
