Specifications for the RF2 SNOMED format.
See https://confluence.ihtsdotools.org/display/DOCRELFMT

Package snomed defines the specification for SNOMED-CT releases in the RF2
format.

See the [release file specifications](https://confluence.ihtsdotools.org/display/DOCRELFMT/SNOMED+CT+Release+File+Specifications)

These are, in large part, raw representations of the release files with some
small additions, predominantly relating to valid enumerations, to aid
computability.

These structures are designed to cope with importing any SNOMED-CT
distribution, including full distributions, a snapshot or a delta.

* Full	   The files representing each type of component contain every version
           of every component ever released.
* Snapshot The files representing each type of component contain one version
           of every component released up to the time of the snapshot. The
           version of each component contained in a snapshot is the most
           recent version of that component at the time of the snapshot.
* Delta	   The files representing each type of component contain only
           component versions created since the previous release. Each
           component version in a delta release represents either a new
           component or a change to an existing component.
