Mapping reference set improvements

It's now possible to create extended map type reference sets. This type of reference set it very similar to complex map type reference sets, but also allows specifying map categories for an associated reference set member. In case of ICD-10 the individual category values are subtypes of 447634004 |ICD-10 Map category value|. For further information about extended map reference set, please refer to the IHTSDO Technical Implementation Guide.

Creating an extended map type reference set

Once reference set members have been published when creating a version of SNOMED CT, it's not possible to delete members of the reference set.

Versioned reference set members can't be deleted

Versioned components can only be inactivated. The Clone and retire function inactivates a mapping and creates a new mapping with the same referenced component. This is useful if you want to change a mapping that has already been versioned, because you only need to define the new target. The function is available for all map type reference sets.

Value domain, mapping set and local code system enhancements

Value domains, mapping sets and local code systems can now be exported on an individual basis, easing the distribution of limited, user-defined content. The exported output contains an index sheet that helps navigating between the different artifacts - this comes handy when a large number of value domains, mapping sets or local code systems are present.

Automapping now uses fuzzy matching when looking up possible matches, providing better mapping and matching power for various use cases. In addition to this, fine-tuning the search profiles also proved useful in increasing mapping efficacy.
