In the system we developed, all code accesses a TPA API. If you are a java-head, this can be explained in one line: TradingPartnerAgreement tpa = TradingPartnerAgreementFactory.create(cpa); >2nd: how exactly are CPAs created? i know that you need two or more cpps and >i have a figure where it is explained. but i guess the figure is quite >theoetic...how is it managed in the daily doing? how much is automated and >how much has to be done by a human being? > > The pattern we always wanted to see would be automatic negotiation of CPAs based on CPPs. A tool would take our CPPs + minimum security and reliability requirements and just automate the process of creating the CPA. This will be a reality soon, as work is ongoing within the CPPA TC to specify how CPA negotiation must work...but for now CPAs are build by hand using an XML editor.
