Requirements

  • Organizations that maintain SNOMED CT edition(s) or extension(s) must distribute one or more release package(s). Each release package must contain a full release for the current version of an edition or extension for which they are responsible. Optionally, each release package may also contain a snapshot release and/or delta release for the same version of the same edition or extension.
  • Terminology service providers must ensure their service is able to import data from either a full or snapshot release of a selected edition or extension. They should also consider enabling the service to update a previously imported edition or extension using a delta release.
  • Healthcare application providers should ensure that their application can work with terminology services that facilitate importing and updating SNOMED CT using the release types available for all the SNOMED CT editions and extensions to which their customers require access.
  • Terminology service users must confirm that the healthcare applications and terminology services they procure can provide access to the SNOMED CT editions and extensions they need to access. They must also confirm that the terminology service facilitates updates to more recent versions of those editions and extensions.

Release Type Characteristics and Uses

Table 5.3.1-1 specifies the content of each of the release types and the types of use that these release types support.

Table 5.3.1-1: SNOMED CT Release Types

Release Type

Description

Usage notes

Full

A release type in which the release files contain every version of every component and reference set member ever released.

The set of full release files for a SNOMED CT edition provides data that enables terminology services to offer access to snapshot views of terminology content at any specified date between its first release and the current release.

The data in a set of full release files for an edition also enables terminology services to provide information about changes made to the content of that edition between any two release dates.

Snapshot

A release type in which the release files contain only the most recent version of every component and reference set member released, as at the release date. 

The version of each component and reference set member in a snapshot release is the most recent version of that component at the time of the snapshot.

  • Components that have been added, changed or inactivated in the current release have an effectiveTime equal to the release date.
  • Components that have not changed since an earlier release have an effectiveTime that matches the release in which they were most recently added, changed or inactivated.
  • Components that are inactive are included and must be distinguished from active components based on the value in the active column.

A set of snapshot release files for a SNOMED CT edition provides data that enables terminology services to offer access to the current release snapshot view of the content of that edition.

Access to snapshot release file data for two or more releases of an edition, also enables terminology services that provide information about changes made to that edition between the release dates of those snapshots.

Delta

A release type in which the release files contain only rows that represent component versions and reference set member versions created since the previous release date. 

Notes

  • Each row in a delta release file represents either a new component or reference set member, or a change to an existing component or reference set member since the previous release date.
  • A delta release identifies differences between two versions of the same release package. 
  • A delta release added to the previous full release is identical to the full release of the new version.
  • The previous release date, on which a delta release is based, is usually the date of the most recent previous release. However, that may not always be the case. For example, where interim releases are made between two major releases there may be a combined delta release covering a period since a previous major release. 

Please note : 

  • Delta files have been removed from the SNOMED International release package, Managed Service Extensions and Derivative packages.  However a Delta Generation Tool is available for those who need it. The Delta Generation Tool allows users to create their own Delta between two fixed release dates - you can find it here: https://github.com/IHTSDO/delta-generator-tool/releases.

The content of a set of delta release files for a SNOMED CT edition cannot be used as a stand alone resource but can be used in the following ways:

  • To update the previous full release data: by adding the data in each delta release file to the current stored version of the full release.
  • To update the previous snapshot release data: by adding new components and replacing existing components with updated versions of those components.
  • To enable review of changes to components since the previous release: by comparing the delta data with the previous snapshot data for the same edition.

Comparing the Content of Different Release Types

Table 5.3.1-2 provides an illustration of the content of the delta, full and snapshot release types across five releases of a simplified example release file. The names of the four columns in this example file match four of the columns in the SNOMED CT descriptions release file. However, to simplify the example, the moduleId, conceptId and caseSignificanceId columns have been omitted, and the values in the id columns are simple integers rather than SCTIDs. Each of the five releases in the diagram is shown with a valid effectiveTime (for presentational clarity the release dates shown are a year apart and the year is shown in bold text).  Table 5.3.1-3 provides a key to use of color shading to highlight additions, changes and inactivations in each version of the release.

Release and NotesDeltaFullSnapshot

20010131 - The first release illustrating the initial content of the release file.

  • In this example, six components are created and included in the first release.

The delta, full, and snapshot release files are identical in the first release because there are no earlier versions of any components.

  • The delta represents the changes from an empty starting file and thus, like the full release, it contains all the component versions ever created.
  • Since there is only one version of each component, this is by definition the latest version of that component, so all the and as there is only one version of each identified component so the same data is also present in the snapshot file.

20020131 - The second release illustrating a change.

  • Component 3 term changed from "3rd" to "third".

The delta file only includes the changed item.

The full file includes all rows in the previous release plus the changed row with the new release date and updated term.

The snapshot view includes only the most recent version of each component. So the initial version of component 3 is omitted.
