 Descriptions adopt the semantics of RDF, especially the open-world assumption. This means that "​violation"​ of a minimum cardinality restrictions in a description does not correspond to an inconsistency,​ but to either a lack of knowledge or a query for a partial description. Descriptions adopt the semantics of RDF, especially the open-world assumption.

-[1] Possible ​Performative ​values are AssertionRetraction, Query, Result, ... +[1] Performative ​is an operation that is expressed directly in the knowledge resource. Languages with this capability include PrologRuleML and DOLA knowledge resource containing performatives is an "​executable knowledge resource"​.
  
-[3] A self-description (of a knowledge resource) ​is a descripton ​embedded in the knowledge resource it is describingIt naturally inherits a number ​of properties from the knowledge resource ​being describedincluding level. Other properties are inherited unless overriden; e.g. language, dialect, format, storeConfig,​ IOMode, Metadata.+[3] The "​hasDescription"​ property ​is a means to embedded ​information about the description ​in the description itselfNote that the subject ​of the ":​hasDescription"​ property is the knowledge resource ​that the description is aboutas named by the ":​hasIdentifier"​ property.
