+== Value range for `samm:curie` values
+
+Values with the type of `samm:curie` are interpreted in the context of the Aspect Model that
+describes the Aspect. The prefix part of their value therefore refers to the RDF prefixes as defined
+in the Aspect Model. Aspect Models do not use the https://www.w3.org/TR/turtle/#relative-iri[@base
+or BASE] directive in RDF/Turtle, so values with `samm:curie` type must always contain a colon `:`
+to delimit the (possibly) empty prefix part from the local name.
