SNOMED CT Snapshot Language Reference Set
A Language reference set is a Component reference set that is used to indicate which descriptions contain terms that are acceptable or preferred in a particular language or dialect. This dataset describes the Release File structure of SNOMED CT, referred to as Release Format 2 (RF2). The US Edition of SNOMED CT is the official source of SNOMED CT for use in US healthcare systems. It combines the content of both the US Extension and the International release of SNOMED CT.

SNOMED CT (SNOMED Clinical Terminology) provides a common language that assists with the electronic exchange of clinical health information. It enables a consistent way of indexing, storing, retrieving, and aggregating clinical data across specialties and sites of care. SNOMED CT Can be mapped to other coding systems, such as ICD-10, which helps facilitate semantic interoperability.
A Snapshot release contains the most recent 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 release time. The ‘Snapshot’ release is useful for a simple installation but does not provide a history or retrospective view of the terminology. There are valid use cases for each Release Type. Each International release will incorporate all three of these Release Types, allowing users to choose the most appropriate format.
The March 2020 release contains relevant COVID-19 concepts including any applicable changes to descriptions. With this interim release, 24 records have been added, plus core concept descriptions added back in referencing March 2020.
With this release, clinicians, researchers and administrators globally are able to code, analyze and plan to address the Coronavirus effort with the most up to date terminology.

|Reference_Set_Member_Id||A field, uniquely identifying this reference set member. Different versions of a reference set member share the same ID but have different Effective_Date. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time.||string||required : 1|
|Effective_Date||The inclusive date at which this version of the identified reference set member became the current version.||date||required : 1|
|Is_Active||The state of the identified reference set member as at the specified Effective_Date. If active= true, the reference set member is part of the current version of the set, if active=false, the reference set member is not part of the current version of the set.||boolean||required : 1|
|Module_Id||Identifies the SNOMED CT module that contains this reference set member as at the specified Effective_Date.||integer||level : Nominalrequired : 1|
|Refset_Id||Identifies the reference set to which this reference set member belongs.||integer||level : Nominalrequired : 1|
|Referenced_Component_Id||A reference to the SNOMED CT component to be included in the language reference set.||integer||level : Nominalrequired : 1|
|Acceptability_Id||indicates whether the description is acceptable or preferred for use in the specified language or dialect.||integer||level : Nominalrequired : 1|
