Contradiction in the supply chain object spec about openrtb

[iantri]

Hi MacCrazyBean,

I think its a matter of poor phrasing, and I'll speak to other working group participants to see if we can/should revise. The first node should represent the first a) advertising system the impression passes through and b) the seller ID on that advertising system.

So, in this phrase:

In a complete supply chain, the first node represents the initial advertising system and seller ID involved in the transaction, [i.e. the owner of the site, app, or other medium].

The part I've put in brackets should be interpreted as referring to the seller ID only. The initial advertising system that touches the impression would be the one with the direct relationship with the publisher and thus the seller ID would represent that advertising system's direct relationship with the site/app/etc.

Makes sense?
