10 Example of Representation

In this Section, we construct an explicit representation of the model for Figure 4. It appears in 17, where we see:

• an explicit enumeration of artifact and process ids (no agent in this graph);
• the symbols O and G to denote orange and green accounts, respectively;
• explicit mappings for processes and artifacts from their ids to their values and accounts;
• in this representation, the "values" of processes is a URI to concepts in an ontology, whereas the "values" of artifacts are immediate;
• the list of edges;
• explicit declaration of refinement.
