Provenance DM WD review - invalidatedAtTime description

[Mathieu Servillat]

Hi,

To be precise and base the discussion on facts rather than opinions, the
previous corresponding attribute (PR 2018-10-15) was indeed:
destructionTime - prov:invalidatedAtTime - datetime - date and time at
which the entity was erased or invalidated

We then received comments during an RFC phase that questioned why some
attribute names were different from the W3C PROV names. It is not my
decision to change this attribute, but a general agreement between the
authors, as is the decision to follow strictly the W3C PROV definitions
when the concepts are exactly the same so as to avoid any confusion (i.e.
all the core model, Activity, Entity, Agent, Used, WasGeneratedBy,
WasAssociatedWith, WasAttributedTo). Further interpretation of this
attribute in the context of an implementation can be discussed elsewhere.

Cheers,
Mathieu
