In life, interesting encounters take place at the borders of different ecosystems. There the interaction can benefit all parties most.
In professional life, such borderlines exist within developing technologies and methodologies. Examples are semantic technologies, enterprise architectural frameworks, service oriented architectures and many others. Within these groups in development different definitions and purposes are advocated. Often lots of time is put (wasted?) in academic discussions, not the least driven by personal sensitivity. After the storm accompanying the birth of a novelty is laid down, borderlines still pop up but spread into time and evolving at a slower pace: the technology becomes mature.
