We are particularly interested by the semantics of a language of interrogation for the structured charts. Structured charts can also be looked at as model binary where examples of entity are represented (only) like marks (for example, a OID) and the two reference-evaluated reports/ratios and attributes are binary relations. In conclusion, note that the title for an entity could in a manner equivalente of being represented as reference-evaluated attribute where the title(s) are ensured in an additional document in the universe of information.
