I propose a new and more general property:

Pnn Activity - was influenced by (influenced) Persistent Item

This would subsume:

P15 Activity - took into account (was taken into account by) Conceptual
Object
P17 Activity - was motivated by (motivated) Man-Made Stuff (why not
Stuff?) (issue 79)

It would also resolve issue 79: Change Property Name P17 was motivation
for to was motivated by

redefine range of:
P15 Activity - took into account (was taken into account by): Persistent Item
I take "took into account" as synonym to "influenced by", as the Actor of the
activity "must let it influence her/him".

redefine range of:
P17 Activity - was motivated by (motivated): Stuff ,

declare P16,P17 as subproperty of P15.

This complements the existing links:
P19 Activity - was intended use of (was made for) Man-Made Stuff
P16 Activity - used specific object (was used for) Stuff (issue 96)

I propose to either add:
Pxx Activity - was influenced by (influenced): E7 Activity

and declare
P18 Activity - was motivation of (motivated) : E7 Activity subproperty of Pxx

Or to generalize P18 into "was influenced by".

The link P20 corresponds to P19:
P20 Activity - had specific purpose (was purpose of) : E7 Activity
(intention, future)

Do we need an equivalent to P16 ?:
Pyy Activity - continued (was continued by) : E7 Activity

To my understanding, this is all that could be said about
influence between activity and stuff, and between activities.
It seems to me complete and symmetric.
