Not really related to this PR, but do you know why we have two methods for representative extraction : extractRepresentative (in entity-representative) and extractStixRepresentative (in stix-representative) ? what is the difference between the two ?

[Archidoit]

@SouadHadjiat : extractStixRepresentative extracts the representative of an entity that is in the stix format, extractRepresentative extracts the representative of an entity in the BasicStoreCommon format

[SouadHadjiat]

Can they return different values ? about the main representative.

[Archidoit]

@SouadHadjiat there are some differences (exemple for Attack Patterns : name in stix representative // composition of x_mitre_id and name in entity representative)
