Provenance DM WD review - invalidatedAtTime description

[Mireille LOUYS]

Hi all,

We are reaching the end of the working draft period. We made many 
changes to the document, following the guide lines of the

agreements  listed after several meetings, with chairs and vice-chairs 
of DM and TCG at interop.

I don't think it is appropriate to rediscuss the names of the attributes 
in the data model classes. We borrowed the /invalidatedatTime/ concepts 
from W3C , it sounds good to name then the same

What we want is a clear document, that people not introduced to 
provenance tracking can understand and figure out in their context .

If some sentences are unclear , this is our job as authors to change 
them. The opinion of just one person does not replace others advices.

Best regards, Mireille
