DATA STRUCTURE
Concept: Represents a medical concept (e.g., disease, procedure, anatomical site). Each concept has a unique identifier (concept ID) and a preferred term.
Description: Provides a textual representation of a concept (e.g., “heart attack”). A concept can have multiple descriptions in different languages and contexts.
Relationship: Defines the semantic relationship between two concepts (e.g., “is a part of,” “is associated with”). Relationships have a type (e.g., “isa,” “is_a_finding_of”) and a direction.
ABSTRACT STRUCTURE
Create a root page: This page will represent the top-level of the SNOMED CT hierarchy.
Createchild pages: For each concept, create a child page of the root page or another concept page. The page title can be the preferred term of the concept.
Use headings: Use headings (e.g., == Concept Name = to represent the concept name.
Add descriptions: Add the concept's descriptions below the heading.
Link concepts: Use internal links (e.g., Concept Name) to link related concepts.
Represent relationships: To represent relationships, you can use a table or a list format. For example:
