7.3. SCOR REFERENCE ONTOLOGY 111<br />

Figure 7.10: SCOR S1 process <strong>of</strong> sourcing stocked product [164]<br />

levels (from level 1 to level 3). SCOR_ORGANISATION are organizations/persons who are<br />

involved in the process elements. The goal ontology in this domain is also from SCOR.<br />

Usually the hard goals are derived from process elements and also from their inputs<br />

and outputs. Per<strong>for</strong>mance attributes defined in SCOR can be modeled as a set <strong>of</strong> General<br />

S<strong>of</strong>t Goal Category such as Reliability, Responsiveness, Flexibility, Cost,<br />

and Assets. Domain specific s<strong>of</strong>t goals are derived from the metrics <strong>of</strong> per<strong>for</strong>mance<br />

attributes [167].<br />

The SCOR ontology is <strong>for</strong>malized in OWL. To organize those concepts, we categorize<br />

domain concepts with the 3A concepts (Activity, Artifact, Actor-role) defined<br />

in GPO. The purpose <strong>of</strong> the categories is to establish the mapping relationship between<br />

a PSAM model and the reference ontology when annotation. The categories<br />

and concepts are modelled as OWL Classes, and they are organized by a subsumption<br />

hierarchy.<br />

The ontology concepts which are organized in "SCOR_MGMT_PROCESS"<br />

are sub-classes <strong>of</strong> Activity, the input/output ontology concepts<br />

("SCOR_INPUT_OUTPUT") are sub-classes <strong>of</strong> Artifact and the organizational<br />

ontology concepts ("SCOR_ORGANIZATIONAL") are sub-classes <strong>of</strong> Actor-role.
