These guidelines were developed to assist map developers in producing a map that benefits all users and ensures that downstream users of data produced by the map can use the information consistently and reliably.
A robust mapping methodology will assist in producing quality maps that are usable, reproducible and understandable.
Quality mappings will support the use cases they were intended for
There is a maintenance in the meaning of the source and target code systems
Mapping needs to be able to be maintained where:
there are updates to the source code system
there are updates to the target code system
there are updates to user requirements or use cases
Clear methodology ensures a repeatable quality approach to mapping
Mappings need to employ authoritative reference sources uniformly
Documentation defines all assumptions, rules, and procedures required to manage context and create the map
All mappings should have a stated purpose and audience
Map documentation is complete, clear, and unambiguous
Mappings define the source and target domain scope for the map
