A dynamic medical object information base (DMOIB) is used with a communication protocol. A medical object information base (MOIB) may generally define rules of creation and modification of data defined for use in medical products. A dynamic version of the MOIB adapts to changing data classifications. DMOIB is preferably compatible with non-dynamic MOIB systems. DMOIB preferably reduces code space and simplifies management of software projects. DMOIB may allow for an entirely dynamic system using a discovery/negotiation process for determining full features of a device. DMOIB may also allow for generation of a dynamic interface to handle data from devices.
