Subject: Re: [xri] GCS Characters


Certainly some apps will use XRI natively.

I think the point Drummond is trying to make is that in the UI for XDI server a user is unlikely to confuse a XRI with a email address.

Outside of XRI aware apps they would be circulating as HXRI as they are today so that legacy apps can do something with them.

Are there native XRI apps that we can see confusing =jbradley@microsoft.com with jbradley@microsoft.com being a problem? 

The above are both relative URI in that the email would be mailto://jbradley@microsoft.com  though most apps don't present them that way.

Is this something that the UI for XRI aware apps can deal with?

Note that mailto://jbradley@microsoft.com may also resolvable to meta-data via XRD.

In past emails I thought we said that the native xri would also still exist. So you could still have =drummond@microsoft.com for applications that understand xri.

Johnís right - =drummond@microsoft.com is just as valid an XRI as @microsoft.com=drummond, and has the same type of global inference. Itís a reference to the organization in the context of the individual, and I can think of lots of uses for such a reference.
 
However I think Steveís original concern is no longer an issue under the new XRI-as-relative-URI architecture, because the XRI bound to a base URI is no longer going to be confused with an email address. Examples:
 
            info:xri/=drummond@microsoft.com
 
In fact, even an ordinary email address when included in the path of a (non-mailto) URI is no longer an email address Ė itís just a path.
 
 
=Drummond

You might want to do it for some malicious reason.
 
If we don't preclude it, the syntax  is valid stupid or not.
 
If @microsoft.com=drummond  is a subject in Microsoft's authority server that it is inferring has something to do with =Drummond then why wouldn't =drummond@microsoft.com be a subject in =Drummond's authority server hat he is inferring has something to do with the global @Microsoft.com
 
If we allow it someone will use it and if it can be misused someone will.
 
Steve's quite legitimate question is will the benefits of saying =drummond@Microsoft.com vs =drummond*(@microsoft.com) outweigh the possible social engineering dangers that are introduced.
 
We need a clear answer to that.  The answer may well be yes they do, but we need to consider it carefully.

Why would you ever want to put a company into the context of an
individual (what does =drummond@microsoft.com mean??). To me it makes
sense only the other way round, i.e. @microsoft.com=drummond.

And something that never appears anywhere can hardly confuse people, or? :)

I spent some time on the phone yesterday with Steve Churchill reviewing the
proposal on GCS symbols in XRI 3.0.
 
He reminded me that one of the original objections was allowing:
 
This in 2.0 would be represented as:
=drummond*(@microsoft.com)
 
In removing the need for parenthesizing cross-references we run the risk of
people misconstruing direct concatenated XRI as email addresses or otherwise
trying to read the first XRI segment from right to left.
 
The problem is alleviated slightly by having the XRI bound to a scheme.
 
This is a  social engineering problem rather than a actual resolution issue.
 
Thoughts?
