Hi Mike,

Thanks for writing this up.

I think we have two different existing mechanisms that are intended to solve this particular use case (of indicating multiple domains that actually belong to the same organization, or party).

P3P defined OUR-HOST:

DNT defines same-party:

I'm uncertain whether either of those are or are likely to be used. We have identified that there may be some issues with keeping such a list up to date if you're a large organization. And more relevant, sites are unlikely to go to the trouble of indicating their party lists unless they see a concrete advantage to doing so. DNT suggests that that's possible depending on how user agents treat unaffiliated domains that all claim first-party status, for example.

I don't see that we need a third mechanism to solve this problem. Mike, if there is a difference, can you explain why this would be more useful than existing solutions? As you note, it might make more sense to take this to a different deliverable or different WG, but I think the same question will apply.


P.S. HTML attachments to emails to public-tracking actually do have Web-accessible permalinks, e.g.: http://lists.w3.org/Archives/Public/public-tracking/2014Dec/att-0000/OperatorIdentity.html

We can also host files on w3.org if necessary, but I think typically it's not necessary, and depends on getting me to commit the files, which is probably an unnecessary roadblock.

What I suggested was that, if we decided we had to lose the “cookie like” domain property from the property bag following Anne van Kesteren’s LC comment, we could refer to a new spec (similar to this one) which would allow cross-origin access for same parties and service providers.
