Addition of cco:CyberObjective class
The Cyber Ontology could benefit from inclusion of a 'cco:Cyber Objective' class, which specializes the cco:Objective class to group together all the classes of objectives of a 'cco:Cyber Attack' (and possibly of all Cyber Acts, i.e., Acts in Cyberspace). Currently, the MITRE ATT&CK Matrix Ontology (MAMO) uses such a class to group together all its Tactic (tactical objective) classes. Adding this class would provide a parallel structure to the grouping of MAMO Technique classes under 'cco:Cyber Attack'. It would also make this class available to other ontologies that extend the Cyber Ontology, such as the tactics of the 'Embedded System TTP Matrix Ontology' (ESTM). If the 'cco:Cyber Objective' remained defined in MAMO, it would require re-defining it for the ESTM ontology, which would create duplicate annotation properties when both MAMO and ESTM are imported into the Ontology for Attacks in Cyber Risk Assessment (OACRA).
