This Recommendation provides a specification for the design of the Human-Machine Interface (HMI) for object browsers. An object browser allows a user to select an object from a group of objects and perform some required functions on that object. This specification is called a pattern. A software pattern is used by designers to generate templates and specific instantiations for products. Object browsing is one of a few generic tasks performed by operators of telecommunications networks across a wide range of network and service management applications.
