To maximize interoperability, you should declare an alias for each event that describes just the data type that it expects or produces; in other words, the minimum requirement for compatibility.

At a minimum, a sensor component must perform the monitoring and detecting functions to detect that the event happened and to create an event object to signal the event.

Only a week after the OSGi Community Event in which a demonstration of the cut-down OSGi-based modular runtime was given, there were discussions of OSGi minimum environments.
