Rich Hilliard, a participant in the workgroup which developed the standard, maintains a website at www.iso-architecture.org which is informative of things related to systems architecture standards. It includes a section on ISO 42010 and discusses the evolution of ISO 42010 from its historical base in IEEE 1471. For those who can not afford, or who may not need, an actual copy of the standard from the standards body, the website also provides an overview and some discussion of the content. That material is further summarized and interpreted here for our purposes. There is also a good summary on the Wikipedia page for the standard: ISO/IEC_42010.
