Authoring Level 2 Competencies: SNOMED CT Authoring

7. SNOMED CT Authoring

6. SNOMED CT Authoring: Required tasks in creating and revising SNOMED CT concepts
Competency Item	Area of Skill	Competency	Level
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	Evaluate
