Hi Khalid,

OK. That is not how I have understood things from the DM.

The DM says "A Usage, start, end, generation, invalidation, communication, derivation, attribution, association, and delegation is also an influence. It is recommended to adopt these more specific relations when writing provenance descriptions. It is anticipated that the Influence relation may be useful to express queries over provenance information."  If you are correct that influence could be used to express provenance relationships between entities that derivation could not capture, then why would we be recommending not to use it?

Can you give me an example of a relationship between entities that is an influence but not a derivation?

thanks,
Simon

Hi Simon,

Thanks for the new entry, which I think will be useful.
Regarding the last sentence, I think it may lead to some
mis-understanding [1], as the reader may think that derivation is used
to express influence between entities, whereas it is used to express a
relation that is stronger than influence.

[1] "For example, if you wish to express the influence of one entity
on another, this can be done with a wasDerivedFrom relation."

Best,
khalid
