The Associative Data Model
I didn’t know much about the ☞ associative data model until now, but this sounds somehow similar to graph databases: items and links having source and target and verbs.
/// Associative data value type Value = /// Item value | Item of string /// Link of source value, verb and target value | Link of Value * string * Value
