Books
This is what is called a collaborative book, for the development of the Sub-Architectures of the Enterprise Architecture. An Enterprise Architecture (EA) is not a one time single document, but rather a collection of models and principles that provide a mental model of organization. Architecture defines the relationships between entities within an organization, just as an architectural blueprint for a building shows the interconnection between parts. Without a blueprint, one can't determine the result of changes made to any individual part on the whole. Enterprise Architecture's goal is to remove inhibitors to change, so an organization can continue achieve its objectives in a constantly changing environment.
Some technologies which have not yet been widely adopted or available, deserve consideration as they mature. Emerging Technology Reports allow for brief analysis of these technology futures, even if adequate information is not yet available for adoption, so that strategic and architectural alignment, and feasibility can be evaluated. It is likely that these reports will be updated as more information becomes available, therefore versioning should be used.
