Attributes

Own

• Proposition➞propositionType _0..*
  • Description: A specific type of proposition the Proposition object represents (e.g. a 'Variant Pathogenicity Proposition', or 'Molecular Consequence Proposition')

• Proposition➞subject _1..1
  • Description: The Entity about which the Proposition is made.
  • Range: Entity
• Proposition➞predicate _1..1
  • Description: The relationship asserted to hold between the subject and the object of the Proposition.
  • Range: Coding
• Proposition➞object _1..1
  • Description: An Entity, concept, or value that is related to the subject of a Proposition via its predicate.
  • Range: Element
• Proposition➞qualifier _0..*
  • Description: A value or concept that extends or refines the meaning of the Proposition expressed by the core subject - predicate - object 'triple' - e.g. by providing additional information/detail, or constraining the claim to apply in a particular context.
  • Range: Element
• Proposition➞negated _0..1
  • Description: A boolean flag set to 'true' if the statement expressed by the subject, predicate, object, and qualifier(s) is explicitly asserted to be false.
  • Range: Boolean

Inherited from Entity:

• Element➞extensionElement _0..*
  • Description: A key-value data structure that allows definition of custom fields to capture information not directly supported by the VA specification.
  • Range: Extension

  • Range: Identifier
• Entity➞globalIdentifier _0..*
  • Description: A business identifier or accession number for the entity, typically as provided by an external system or authority, that is globally unique and persists across implementing systems.
  • Range: Identifier

  • Range: Class
• Entity➞label _0..1
  • Description: A primary name for the Entity.
  • Range: String
• Entity➞alternativeLabel _0..*
  • Description: An alternative name for the Entity.

Other properties

Comments:		Propositions are taken to represent the semantic content of sentences or larger lexical entities formulated in some natural or artificial language. As primary bearers of truth, they are either true or false. They are abstract entities whose identity and existence are independent of space and time, and of whether they are ever asserted to be true by some agent. Propositions are ‘sharable’ in the sense that the same Proposition instance can be expressed in many different Statements, as made by different Agents and/or on different occasions.
