SNOMED CT Snapshot Module Dependency Reference Set
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. The US Edition is a standalone release that combines the content of both the US Extension and the International release of SNOMED CT.
The Module dependency reference set is used to represent dependencies between modules, taking account of module versioning.

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.

|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||The identifier of a target module on which the dependent module (identified by Module_Id) depends.||integer||level : Nominalrequired : 1|
|Source_Effective_Date||The effective date of the dependent source module (identified by Module_Id). This specifies a version of that module, consisting of all components that have the same Module_Id as this refset member in their states as at the specified Target_Effective_Date.||date||required : 1|
|Target_Effective_Date||The effective date of the target module required to satisfy the dependency (identified by Referenced_Component_Id). This specifies a version of that module, consisting of all components with the moduleId specified by Referenced_Component_Id in their states as at the specified Target_Effective_Date||date||required : 1|
