Tell me more about the Machine Readable Concept Model (MRCM).

StepsReferences

Find the desired domain name in the Domain panel of the MRCM Maintenance Tool.

Press the name to change the context of the Applicable Attributes panel to those matching the domain, and also expand the Domain Details sub-panel at the base of the Domain panel. The selected domain name is highlighted.

The Domain Details sub-panel can be toggled closed/open when a domain name is selected. This presents details corresponding to the MRCM domain reference set fields for the selected domain:

  • Domain Constraint (ECL expression)
  • Parent Domain (sub-domains only)
  • Proximal Primitive Constraint (ECL expression)
  • Guide URL (link to the relevant section of the SNOMED CT Editorial Guide)
  • Precoordination Domain Template (ECL expression)
  • Postcoordination Domain Template (ECL expression)

When open, press   on the right of the sub-panel title bar to close the Domain Details sub-panel.

When closed, press   in the sub-panel title bar to open it.


The Applicable Attributes list can be filtered by typing a text pattern into the Filter Attributes... box. As soon as text is entered, the attributes list will update to only show those matching the filter text (which may only be one, or none at all).

The Applicable Attributes list can also be filtered by entering an SCTID into the Filter Attributes... box.

If the SCTID matches an attribute applicable to the selected domain then only that attribute is presented (since its SCTID is an exact match). If an entered SCTID does not match an attribute applicable to the selected MRCM domain then the attribute list will be blank.

If a sub-domain is selected, the Applicable Attributes results will show all those applicable to its parent domain, however only those applicable to the selected sub-domain will be active in the list.

Any attributes not applicable to the selected sub-domain will be inactive, and moving the cursor onto them will show a symbol, indicating they cannot be viewed for the selected sub-domain.

Find the desired applicable attribute name in the Applicable Attributes panel listing.

Press the name to change the context of the Attribute Range panel to those matching the attribute, and also show the Attribute Details sub-panel at the base of the Applicable Attributes panel. The selected attribute name is highlighted.

The Attribute Details sub-panel presents details corresponding to the MRCM attribute domain reference set fields for the selected attribute:

The Attribute Details sub-panel shows values for:

  • Grouped (checkbox)
  • Attribute Cardinality (range)
  • Attribute in Group Cardinality (range)
  • Rule Strength (text)
  • Content Type (text)

The Attribute Range panel presents details corresponding to the MRCM attribute range reference set fields for the selected attribute:

  • Range Constraint (ECL expresssion)
  • Attribute Rule (ECL expression)
  • Rule Strength (text)
  • Content Type (text)

On selecting an applicable attribute, a search is performed to retrieve all concepts matching the range constraints. After a brief pause (search time depends on the complexity of the search and number of results obtained) the results are presented in a sub-panel at the base of the Attribute Range panel.

The Attribute Details sub-panel can be toggled closed/open when an attribute is selected.

When open, press  on the right of the sub-panel title bar to close the Attribute Details sub-panel.

When closed, press   in the sub-panel title bar to open it.
