Requirements-Annotations
Annotations are a set of free-hand descriptive elements that accompany most, though not all HL7 v3 artifacts and sub-artifacts. They are broken up into a series of categories, each having a distinct objective and target audience. Some may have additional supplemental metadata. Each artifact or component of an artifact that allows annotations identifies exactly which types of annotations are allowed for that particular element based on what makes sense for that element. For example, formal constraints may make sense for static model elements, but have little relevance for concept domains which are purely descriptive in nature and have nothing to formally constrain.

| Requirement | All major HL7 artifacts and artifact components require either a description that identifies what the element is or a definition that provides the semantic meaning for that element. |
| Rationale | Some HL7 artifacts and components convey explicit semantic meaning, for example classes, attributes, concept domains, coded concepts, etc. Other artifacts do not represent particular meaning but still require an explanation of that the artifact is and why it exists.
Lack of documentation on an artifact or component can lead to confusion about what the artifact or component is or what it's for. |
