6.1

Authoring Platform

Effectively use the SNOMED CT Training Authoring Platform to perform authoring tasks

Apply

6.2

Platform Rules

Ability to abide by Authoring Platform Terms of Usage

Apply

6.3

Authoring Process

Create or modify SNOMED CT content to a high standard in the following hierarchies: Procedure, Clinical Finding and Situation with Explicit Context

Create

6.4

Editorial Guides

Find and apply all relevant guidance when authoring content including naming conventions and concept modelling

Apply

6.5

Descriptions

Develop the most appropriate descriptions (Fully specified names and synonyms) to capture the precise concept meaning. Select the correct hierarchical semantic tag. Avoid creating any description that is not semantic equivalent to the FSN 

Create

6.6

Case significance

Decide on the correct case significance for each description

Apply

6.7

Reference Set preference

Determine the language reference set preference settings

Evaluate

6.8

Proximal Primitive Parent Modelling

Choose the most appropriate proximal primitive supertype(s) including where necessary intermediate proximal primitive concept(s). Create accurate attribute-value pair relationships to express the meaning of the concept.

Apply

6.9

Intermediate Primitive Parent

Know what an intermediate primitive concept is, and manage the challenges of finding and using proximal intermediate parents when appropriate. Author concepts that have intermediate primitive parents and interpret whether after classification the resulting hierarchical position is correct. Correctly follow guidance on whether to choose a GCI concept as a parent or a higher level primitive concept

Evaluate

6.10

Stated, Inferred and

Authoring Form View

Understand the differences between the stated, inferred and authoring form views in the SNOMED International Authoring Platform and use views in the creation and analysis of classified concepts

Analyse

6.11

Relationship grouping

Apply the correct relationship groups to a concept in accordance with Editorial Guidance

Apply

6.12

Definition status

Evaluate whether an axiom definition meets the “necessary and sufficient” condition to be sufficiently defined

Evaluate

6.13

Classification

Apply description logic knowledge to evaluate classification results and any subsequent modelling changes

Apply

6.14

Description Changes

Change or inactivate descriptions by applying the principles for allowed description changes, including the rules that apply for the different description types e.g. not semantically equivalent synonyms

Apply

6.15

Logical Definitions Changes

Perform definitional changes to concepts after evaluating the principles around changing the logical definition of a concept including what changes are permitted to SNOMED CT relationships, what types of changes may be made to a relationship group, and the implications surrounding changes to a concept's definition status

Apply

6.16

Concept Inactivation

Ascertain when an existing concept in SNOMED CT should be inactivated and select the correct inactivation reason. Correctly inactivate a concept using awareness of reference set mechanisms that ensure persistence of meaning when a concept is inactivated. Be able to accurately perform complex inactivations, where the inactivated concept is the target of historical associations and/or an attribute value for another concept and/or has subtypes.

Apply

6.17

Concept reactivation

Determine the necessary steps and modeling requirements (primitive parent(s), defining attributes) to reactivate a previously inactivated released concept

Evaluate

6.18

Attribute Value Concepts

Assess the impact on other content of adding a concept that may be used as the value of an attribute in the definition of other concept relationships

Evaluate

6.19

Concept review

Review the accuracy of new and existing concept descriptions and relationships, as well as evaluating their hierarchical position
