SNOMED CT Delta Relationship
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 Relationship file holds one relationship per row. Each relationship is of a particular type, and has a source concept and a destination concept.

Description
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 Delta release contains only those component versions created, inactivated or changed since the previous release. The ‘Delta’ release is much smaller than a ‘Full’ release and is ideal for updating a ‘Full’ release of the previous version. Adding a ‘Delta’ release to the previous version’s ‘Full’ release will update the installation to a ‘Full’ release of the current Version.

Data Fields
Name | Description | Type | Constraints |
---|---|---|---|
Relationship_Id | Uniquely identifies the relationship. | integer | level : Nominalrequired : 1 |
Effective_Date | Specifies the inclusive date at which the component version's state became the then current valid state of the component | date | required : 1 |
Is_Active | Specifies whether the relationship's state was active or inactive from the nominal release date specified by the Effective_Date | boolean | required : 1 |
Module_Id | Identifies the relationship version's module. | integer | level : Nominalrequired : 1 |
Source_Id | Identifies the source concept of the relationship version, i.e., the concept the relationship version emanates from. | integer | level : Nominalrequired : 1 |
Destination_Id | Identifies the concept that is the destination of the relationship version. | integer | level : Nominalrequired : 1 |
Relationship_Group | Groups together relationship versions that are part of a logically associated relationship group. All active Relationship records with the same Relationship_Group number and Source_Id are grouped in this way. | integer | level : Nominalrequired : 1 |
Type_Id | A concept enumeration value from the metadata hierarchy that identifies the semantic type of the relationship version. | integer | level : Nominalrequired : 1 |
Characteristic_Type_Id | A concept enumeration value that identifies the characteristic type of the relationship version (i.e. whether the relationship version is defining, qualifying, etc.) | integer | level : Nominalrequired : 1 |
Modifier_Id | A concept enumeration value that identifies the type of Description Logic (DL) restriction (some, all, etc.). | integer | level : Nominalrequired : 1 |
