WE have iGov tomorrow. I encourage those that are on the workgroup to come to discuss this, as we have made a bunch of changes (to include some recommended by Phil) and will be going to a vote soonest. I can assure you that even though USG requirements are represented in the draft, it isn’t interoperable and is inline with other international use cases.

Subject: Re: [VoT] IPR disclosures

We should probably try and keep the VOT and iGov discussions separate.

IGov's use of VOT should largly be on the iGov mailing list at the OIDF.  VOT is only a small reference in iGov.  If that needs to be expanded then discuss over there.

This list is for the core VOT spec, and it's fitness to purpose.

Concrete examples of profiles for security token trust that cannot be accommodated by VOT would be helpful when making points that the spec is inadiquate in some way.

Taking off yet again, so out of communication for at least 12h.

As the USG rep, I can confidently state that the use case this version supports is 90% of our use cases. Don’t hold us up for the last 10%. That 10% will be amazing, but can come later. What is being asked for is gold-plating, not something that if not done means we are wrong.

I'm on the side of "get it right".  OpenID swept a similar range of topics into the "out of scope" basket, which rendered their first standard so unusable they had to come back and do a second one.

Lets at least learn from history, and build something *effectively useable* out of the gate.

You can't drive unsafe or inappropriate cars on any roads, let alone in a SAML lane.  Nobody cares *how* it goes wrong, they just care that it did - so it's our job to look ahead and watch out for those obstacles now; rather than shroud them in SEP<>amp;reserved=0>.

Kind Regards,
Chris Drake

Fine. But as I have said you want a unicorn when we just want a car that can drive in the same Lane as SAML. Your unicorn is coming, as the phases of igov include international agreement on vot vectors/values and attribute metadata to assert 'assurance' of attributes that are unrelated to proofing.

I happy for your contribution don't take unicorn comment poorly. Just a quick post turkey dinner way of making a point. Happy US Thanksgiving.

The issue i am concerned about then is that by leaving out the issue of claims than the vot is incomplete and would require a separate statement.

This leads to a lot of interop and complexity problems down the road.  Which value wins etc given they would overlap.

The vot does not have to address it now but it should have the capability to do so (that may not be possible without a model).

This is a lot like when we found loa was actually multi dimensional and it had to dramatically change.  IAL falls into the same problem.

As part of the write-up for the Vectors of trust document, we need an

Are you aware of any IPR related to the following VOT document?

Please reply to the list.

I am not.
