Version compare editor improvements

The compare editor was modified to facilitate reviewing change details when comparing versions. The change details section now contains the following columns:

  • Change: Type of change (new, modified, deleted)
  • Component: Concept name
  • Component type (e.g. relationship, concept)
  • Property (e.g. status, effective time)
  • From: Previous state of the component (e.g. active)
  • To: New state of the component (e.g. inactive)

The columns can be sorted by clicking on the header.

Export change details

It’s now possible to export the content of the compare editor as a text file. To invoke the wizard use the export button in the toolbar of the compare editor. The delimiter separated text file can be imported into Excel.

Exporting change details

The destination file can be opened using Excel.

Patch compare

The patch compare feature allows comparing the original version (source) with the current state of a patch (destination). For example, if you made changes to a the 2013-07-31 SNOMED CT release, you can compare the original release with the latest state of your patched SNOMED CT release (2013-07-31*). It’s not possible to compare different versions of a patch with each other.

The compare patch wizard can be invoked at Tools > Patch compare … or directly from the toolbar button. Select a patched version that you want to compare. The patch is always compared with the original version, so it’s not necessary to select a comparison source. Click Finish to start the comparison.

Selecting a patch version for comparison

The comparison editor is similar to the one described in the section about comparing versions.

Reference sets

Extended map type reference set

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, refer to the IHTSDO Technical Implementation Guide.

To create an extended map type reference set, click on the corresponding button in the main tool bar . You can also right-click on the folder in the reference set view and select New extended map type reference set from the context menu.

The Referenced component is SNOMED CT concept. As a Map target, you can select: ICD-10, ICD-10-AM or Unspecified. Click Finish to proceed.

Creating an extended map type reference set

The default setting for map category is Map source concept cannot be classified with available data. Use the quick search wizard to specify a map categories. As you can see in the screenshot, only valid results that are subtypes of the metadata concept ICD-10 Map category value are displayed.

Specifying map category

When adding a member to a reference set, you can now use the integrated quick search.

Quick search is available for the following components

  • Simple type reference set: Module, Referenced component (see screenshot).
  • Query type reference set: Module.
  • Attribute value type reference set: Module, Referenced component, Value.
  • Simple map type reference set: Module, Referenced component, Map target.
  • Complex map type reference set: Module, Referenced component, Map target, Correlation.
  • Extended map type reference set: Module, Referenced component, Map target, Correlation, Map category.

Query type reference set

When adding a member to the query-type reference set, the syntax is now displayed in ESCG formatting. The module can now also be changed directly in the wizard.

Clone and retire

When a version of SNOMED CT is created, it’s not possible to delete members of a reference set anymore (see screenshot). Versioned components can only be inactivated.

Versioned reference set members can’t be deleted

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.

Right-click on the mapping that you want to change, and select Clone and Retire from the context menu.

Cloning and retiring a mapping

A clone of the mapping with the same referenced component is now available in the wizard. Select the new map target and Finish.

Note: To inactivate a mapping completely, change its status from active to inactive in the editor, and Save.

Value Domain, Mapping Sets, and Local Code Systems

Index sheet about export

When exporting value domains, local code sets and mapping sets, an index sheet is now generated in first tab of the excel spreadsheet. Links allows easy navigation between the tabs.
