SAF Ontology Elements
The Elements of the SAF Ontology are listed in the following Table. The Table contains two kinds of Elements:
- Relations between Elements that are subject or objects. These are documented in a "triple Form", e.g. Function - Has- Parameter.
- Elements used as subject or objects

Any SAF Element | A concept used only together with relational concepts to specify that the relation goes to any other SAF Concept. | |||
Argument | An argument is a rule that provides the bridge between what we know or are assuming (sub-claims, evidence) and the claim we are investigating. The argument used depends on the type, trustworthiness and extent of available evidence and the nature of the claim. | Claimable Item | Argument Decomposition , Argument Substitution , Argument Concretion | Argumentation Assurance Viewpoint |
Argument Concretion | This argument concept is used when a claim needs to be given a more precise definition or interpretation. | Argument | ||
Argument Decomposition | This argument concept is used to claim that a conclusion about the whole object or property can be deduced from the claims or facts about constituent parts. Decomposition argument blocks can also be used to incorporate defeaters into the case. | Argument | ||
Argument Substitution | This argument concept is used to claim that if a property holds for one object, then it holds for an equivalent object. Similarly, if a property holds for some object, then an equivalent property will also hold for the same object. The nature of the equivalence will vary with the object and property and will need to be defined. | Argument | ||

Note, that typically the usage of logical elements in a context is mapped to the usage of physical elements in a context (allocation of usage). Thus this relationship between the definitions is derived. | |||

System Capability | 1) A System Capability is an operation or task that performs an action to produce a specific performance-based outcome. NOTE that a system capability represents the potential to perform an action. In contrast, an operational capability may integrate several physical system capabilities to produce a specific outcome to achieve a mission objective. [Wasson2006, SystemAnalysis+Design+Development] 2) System Capabilities, as system assets, characterize the mechanical, electrical, optical, or processing features that enable a system to function, process mission resources, make decisions, and achieve a required level of success based on performance. A system capability is broader in scope than simply a functional element (and performance bounding elements), especially in large, complex ecosystems. It represents a physical potential - strength, ability, endurance - to perform an outcome-based action for a given duration under a specified set of operating environment conditions.

Furthermore, a System Function does not need to accept any input from the system boundary, when it is dependent on the System State, which in turn is changeable by other System Functions. | General Function | System Process Viewpoint , System Requirement Traceability Viewpoint , System Functional Breakdown Structure Viewpoint , System Functional Refinement Viewpoint , System Capability Mapping Viewpoint , Logical Functional Mapping Viewpoint , Physical Functional Mapping Viewpoint | |
