Is LinkML mapped to ISO 11179-3?

Good Q!

The LinkML metamodel is strongly influenced by and attempts to conform to the model in ISO/IEC 11179-3 - Metadata registries -- Part 3: Registry metamodel and basic attributes.

AFAIK there are not specific PURLs for the different elements of ISO-11179-3, but as a rough sketch:

• Data Elements (DEs) typically map to slots/attributes
• The Data Element Concept (DEC) is indicated using the slot_uri and class_uri or the containing class
• The Value Domain (ED) is the range of the slot, which will typically be an enum or a type
  • Enumerated Value Domains (EVDs) map to LinkML enums, and Permissible Value (PV) to LinkML PermissibleValue
    • Value Meaning (VM) are represented using meaning in LinkML
  • Described Value Domains (DVDs) (e.g. string for a description, bool for Y/N, measurement values) to LinkML types

Here are some early sides from the LinkML drive illustrating the mapping:
