documentation
Aspect used for storing all applicable documentations on assets. This aspect supports multiple documentations from different sources. There is an implicit assumption that there is only one documentation per source. For example, if there are two documentations from the same source, the latest one will overwrite the previous one. If there are two documentations from different sources, both will be stored. Future evolution considerations: The first entity that uses this aspect is Schema Field. We will expand this aspect to other entities eventually. The values of the documentation are not currently searchable. This will be changed once this aspect develops opinion on which documentation entry is the authoritative one. Ensuring that there is only one documentation per source is a business rule that is not enforced by the aspect yet. This will currently be enforced by the application that uses this aspect. We will eventually enforce this rule in the aspect using AspectMutators.
