Provenance Implementation and Test Cases

  • Finalization of 2nd Questionnaire

Named graphs requirements

Adopting naming conventions

Reaching consensus on naming conventions for both the model and the ontology.

    • Cases
To adopt camel case notation. In OWL, classes begin with upper case, and properties begin with lower case.
    • Nodes (in the graphical representation)
To express nodes in noun form
e.g., entity, processExecution, agent
e.g., Entity, ProcessExecution, Agent

    • Edges (in the graphical representation)
To express edges in verbal form
e.g., uses, isControlledBy, isComplementOf
e.g., isControlledBy, isDerivedFrom
    • Edge directionality
Edges that indicate event ordering must point "towards the past".
    • Tense: we'll debate whether we want present or past tense for edges.

Provenance Ontology

  • OWL ontology progress review (Satya and Tim)
  • Feedback from trying out the use case (Helena Deus)

Provenance Model Document

  • Soliciting feedback
