This is not the answer to my question. I asked about adding support for another language, not how the models are architected. Vendors can (and, in my personal opinion, will) provide proprietary and standard data models. The operator can choose then which model they want to use for their purposes. > Same problem exists with MIBs. When different implementations of the same thing use different base assumptions, it can be difficult to come up with a management model that is congruent with all of the different base assumptions and is still useful. I wouldn't say it's impossible, but it's a good bet that a poorly thought out model or a model that is based on experience with a single implementation will fail in this regard. >
