Hi All --|
I have been lurking on this discussion for a while, and have found it most interesting. Thanks to Ed, Paolo, Mathew et al.
As I understand it, it's a discussion about ontologies, but currently mainly using civil engineering practices as an analogy. Another useful analogy might be dictionary construction -- new terms are frequently introduced to track real world usage, and existing terms get their meaning changed, also by usage .
There seems to be a tension. On the one hand, a useful ontology is supposed to be "right", in the sense that it will not be necessary or desirable to change it much. On the other hand, an ontology is supposed to capture some aspects of the changeable real world. But, if an ontology is used to support, say, interoperation of 100 legacy systems in an SOA architecture, then making a change could break many of the interoperations.
So, a key aspect of using ontologies in practical situation would appear to be to have some reliable change management method or better, change management software. The software would have to be able to run automated regression tests over the entire collection of SOA of legacy systems after each change to the ontology. Also, the software would need a user interface that business folks could understand, without mediation by IT specialists.
Sounds like quite a challenge. Or, is there a better way?
Cheers, -- Adrian
