Should we consider the SO Reference Model for Open Distributed Processing (RM-ODP) model for structuring their analysis?

Gary –
I’d suggest being a little careful about RM-ODP. It is really just the old ANSA model of Andy Herbert from the seventies – including object orientation now somewhat deprecated for dynamic virtualised scaleable environments.
Like OAIS for preservation it provides a sort of container architecture but implementations vary wildly.
Its use in some European funded projects has not been very successful. In fact RM-ODP mixes up stakeholders and views whereas one stakeholder may have many views of the system (one stakeholder may have views on information and engineering for example).
I’d suggest the most effective sysdev method is rapid spiral prototyping (derivative from Boehm) using extended transition nets for process and extended entity-relationship modelling for information(this captures semantics ina way that typical RM-ODP does not).
Just my 2 cents worth!

Subject: [rda-datafabric-ig] Should we consider the SO Reference Model for Open Distributed Processing (RM-ODP) model for structuring their analysis?
Alan provided some cautionary advice on the impact of model complexity as we go forward with more structure and functional details. We have a start on a ReUse scanario from Beth and that version has detail to start with.
John Henry proposed a system engineering view...
Others have tried to address structure and function complexity in ther (use case) scenarios and related architecture and I wanted to point out the approach for a Big Data scenario (see https://www.rd-alliance.org/group/big-data-analytics-ig/wiki/big-data-us...)
They employ the ISO Reference Model for Open Distributed Processing (RM-ODP) model for structuring their analysis. As they note;
"RM-ODP appears particularly useful in situations where multiple stakeholders with divergent background need to converge. To facilitate information collection, RM-ODP comprises five different views on digital systems (see their Fig. 1). "
This avoids in a way a particular {implmentation) architecture and they argue:
"serves for presenting contributions in a structured manner and avoiding lengthy discussions arising from different viewpoints. The RM-ODP approach allows each contributor to individually pick the appropriate viewpoint and make their case."
Thoughts on using this 5 model view (engineerng, computation, tech, information and engineering)????
