| abi | has backing data source | Relates an entity to the data source that provides the underlying data for that entity. This property indicates the origin or source of the data that supports the entity. | A report entity may have a backing data source that provides the raw data used to generate the report. | entity | Data Source | - |

| cco | is output of | x is_output_of y iff x is an instance of Continuant and y is an instance of Process, such that the presence of x at the end of y is a necessary condition for the completion of y. | continuant | process | has output | |
| cco | is input of | x is_input_of y iff x is an instance of Continuant and y is an instance of Process, such that the presence of x at the beginning of y is a necessary condition for the start of y. | continuant | process | has input | |
| cco | is affected by | x is_affected_by y iff x is an instance of Continuant and y is an instance of Process, and y influences x in some manner, most often by producing a change in x. | continuant | process | - | |
