Module scope

To start authoring MRCM content and to be able to validate extension content through MRCM rules you will need to set up the module scope reference set for your extension. This reference set helps establish the scope of editable rules. They also tell the validation processes and which rules to run against your extension content.

You can create the necessary module scope members from the editor with the help of the Initialize MRCM reference set button at the top right corner of the editor. The warning and the hint in the header will prompt you to use this action as well.

MRCM editor without extension content

The MRCM editor always opens using the current codesystem's module scope. If you haven't created the necessary module scope members yet, it will have no rules to display, even if you are working with a data set that has international MRCM rules in it already.

This action will open the following wizard.

Initialize MRCM refrerence sets wizard

Under module scope, you will be able to choose one of the modules that belongs to your extension. Once you've made a choice the rest of the wizard will become enabled too and you will have to choose one of two options.

Use existing MRCM rules option

You can either extend an existing rule set by choosing the first option Existing MRCM rules or you can choose to create all MRCM rules needed by your extension from scratch by choosing the Custom new MRCM rule reference sets.

In the first case, no new MRCM reference sets will be created, but three new entries will be added to the MRCM module scope reference set that link the current international reference sets to your extension module as can be seen below.

In the second case, you will have to specify the names of the three new reference sets in which the three different types of MRCM members will be stored. The wizard will autofill a suggested name for these reference sets, but you may customize it as you see fit.

Custom new reference sets option

In this case, too, three new module scope members will be created, but this time they will link your extension module to the new reference sets.

In case you chose to maintain MRCM rules in custom new reference sets, the editor will still be empty as adding MRCM members is yet to be done. In case you chose to use an existing rule set those rules will appear in the MRCM editor now.

If you would like to view an existing rule set, you can do so by using the Update module scope button at the top right corner of the editor.

Update moduel scope wizard

The resulting wizard will let you choose from modules that have been added to the Module scope reference set (in our example SNOMED CT core and Example extension module). After hitting Finish, the MRCM editor will be updated with content from the MRCM rule reference sets corresponding to the chosen module within the Module scope reference set.

Note that this action doesn't change the module scope for your extension or what rules apply to your extension. It only lets you view content in other module scopes. You can use the same action to switch back to your extension's module scope. The header of the editor displays the current module scope selection for clarity.
