  • Context and actions bar
  • Domain panel
  • Applicable Attributes panel
  • Attribute Range panel

The header contains site branding and an MRCM version selector to its left (the default selection is the current authoring cycle content, ie the MRCM content for the next SNOMED CT release).

link (pressing the account name toggles the link visibility). Follow that link to log out and exit the application (this returns you to the IMS Log in to the Authoring Platform screen).

Below the header, the context and actions bar runs across the three main content panels. Currently selected items appear to the left of this bar (initially empty when nothing is selected), and a RESET button is available to its right (this clears any selections and initialises the content panels).

The Domain panel shows a nested tree-view listing of SNOMED CT domains . Navigate the tree-view listing to browse the and sub-domains.

By default the Applicable Attributes panel shows all available attributes. When an applicable attribute is selected, the Attribute Range panel shows that attribute's range details.

The footer contains a copyright notice, help link (which opens the MRCM Maintenance Tool section of this use guide), and a contact us link (identical to that in the Authoring Platform footer).

The default option is MAIN which selects the MRCM content defined on the International Authoring Platform for the current authoring cycle, and so which will be in the next SNOMED CT release (by its nature this content is subject to change). The other options are previous published versions of SNOMED CT, each of which shows the version of MRCM included on their release.

Domains can also be filtered by entering an SCTID into the Filter Domains... text box. If the SCTID matches an MRCM domain then only that domain is presented (since its SCTID is an exact match). If an entered SCTID does not match an MRCM domain then the domain list will be blank.
