Identify the problem
This example is concerned with the evolution of a crime statistics file (referred to as e0) stored on a shared file system and which journalists Alice, Bob, Charles, David, and Edith can share and edit.
The use of provenance
Provenance tracks the various stages of cooperative document editing. Specifically:
Event evt1: Alice creates (activity: a0) an empty file in /share/crime.txt. We denote this file e1.
Event evt2: Bob appends (activity: a1) the following line to /share/crime.txt: "There was a lot of crime in London last month."
We denote the revised file e2.
Event evt3: Charles emails (a2) the contents of /share/crime.txt, as an attachment, which we refer to as e4. (We specifically refer to a copy of the file that is uploaded on the mail server.)
Event evt4: David edits (activity: a3) file /share/crime.txt as follows: "There was a lot of crime in London and New York last month."
We denote the revised file e3.
Event evt5: Edith emails (activity: a4) the contents of /share/crime.txt as an attachment, referred to as e5.
Event evt6: between events
