Current
Technologies that are supported by the standards and meet the requirements of the architecture. They are recommended for use.
Contain
Technologies that are no longer the standard. They will be phased out over time. Extensive modifications to these systems require review to determine if newer technology should be used. No date has been set for their discontinuance.
Retire
Technologies that are being phased out. Plans should be developed to phase out and replace, especially if there is risk involved such as lack of vendor support. A date for discontinuance has been set.
Research/Emerging
Technologies that have the potential to become current. At the present time, they should be used only in pilot or test environments where they can be evaluated. They will require a waiver request to be used in a limited production mode. Research technologies are less widely accepted and it is too early to determine if they will become a standard. Emerging technologies are likely to become a standard within the next 3 years.
