Dear all, Graham recently, and Simon previously, suggested that we define an entity as an identifiable characterized thing. Such a definition would be appearing in section 2.1 [1]. This would work since PROV-DM has a notion of 'Entity Expression' for the provenance record that describes an entity. Hence, there would be no confusion between an Entity Expression and an Entity. It would further simplify the writing and presentation of PROV-DM, because we could simply talk about entity, rather than 'identifiable characterized thing'. The prupose of this email is to confirm that we want to adopt this terminology. PROPOSED: in section 2.1 [1], to define an entity as an identifiable characterized thing. Can you confirm your support or not for this proposal? If not, can you explain your reasons? Assuming we go ahead with this proposal, section 2.1 would define : - 'Entity' and - 'Activity', whereas section 5.2 [2] would define: - 'Entity Expression' and - 'Process Execution Expression' This is not symmetric and this is confusing. This issue (PROV-ISSUE-129) was also raised by Yolanda. The term 'Process Execution' is dating back from the charter, and was never questioned. It feels that Activity is more intuitive and broader than process execution. In the spirit of simplification [3] of the presentation and model, I am suggesting, the following. PROPOSED: to rename 'process execution' by 'activity' Again, can you express your support or not for this proposal. If you don't support it, can you make a counter-proposal. It feels that keeping both 'Activity' and 'Process Execution Expression' is not suitable: so the status quo is not an option, really.
