Proposed Definitions for the Concept 'Ordering of processes'

Definition by Satya

Ordering of processes (in provenance) needs to be modeled as a property linking process entities in specific order along a particular dimension (temporal or control flow)

In the ProvenanceExample:

• government (gov) converts data (d1) before government (gov) publishes RDF data (f1)
• government (gov) publishes an update (d2) after government (gov) publishes RDF data (f1)
