The domain entity enforces that all project namess under the domain domain be unique, but really what we should say is that all projects under a single parent project be unique. However, we have, at present, an API which allows a user to specify the domain either name or id and project again, either by name or ID, but here we care only about the name. This can be used either in specifying the token, or in operations ion the project API.<br>
<br>
We should change projec naming to be nestable, and since we don't have a delimiter set, we should expect the names to be an array, where today we might have:<br>
<br>
"project": {<br>
"domain": {<br>
"id": "1789d1",<br>
"name": "<a href="http://example.com" target="_blank">example.com</a>"<br>
},<br>
"id": "263fd9",<br>
"name": "project-x"<br>
}<br>
<br>
we should allow and expect:<br>
<br>
"project": {<br>
"domain": {<br>

"name": "<a href="http://example.com" target="_blank">example.com</a>"<br>

"id": "263fd9",<br>
"name": [ "grandpa", "dad", "daughter"]<br>

This will, of course, break Horizon and lots of other things, which means we need a reasonable way to display these paths. The typical UI approach is a breadcrumb trail, and I think something where we put the segments of the path in the UI, each clickable, should be understandable: I'll defer to the UX experts if this is reasonable or not.<br>
<br>
The alternative is that we attempt to parse the project names. Since we have not reserved a delimeter, we will break someone somewhere if we force one on people.<br>
<br>
<br>
As an alternative, we should start looking in to following DNS standards for naming projects and hosts. While a domain should not be required to be a DNS registred domain name, we should allow for the case where a user wants that to be the case, and to synchronize nam,ing across multiple clouds. In order to enforce this, we would have to have an indicator on a domain name that it has been checked with DNS; ideally, the user would add a special SRV or Text record or something that Keystone could use to confirm that the user has oked this domain name being used by this cloud...or something perhaps with DNSSEC, checking that auser has permission to assign a specific domain name to a set of resources in the cloud. If we do that, the projects under that domain should also be valid DNS subzones, and the hosts either FQDNs or some alternate record...this would tie in Well with Designate.<br>
<br>
Note that I am not saying "force this" but rather "allow this" as it will simplify the naming when bursting from cloud to cloud: the Domain and project names would then be synchronized via DNS regardless of hosting provider.<br>
<br>
As an added benefit, we could provide a SRV or TEXT record (or some new URL type..I heard one is coming) that describes where to find the home Keystone server for a specified domain...it would work nicely with the K2K strategy.<br>
<br>
If we go with DNS project naming, we can leave all project names in a flat string.<br>
<br>
<br>
Note that the DNS approach can work even if the user does not wish to register their own DNS. A hosting provider (I'll pick dreamhost, cuz I know they are listening) could say the each of their tenants picks a user name...say that mine i admiyo, they would then create a subdomain of <a href="http://admiyo.dreamcompute.dreamhost.com" target="_blank">admiyo.dreamcompute.dreamhost.com</a>. All of my subprojects would then get additional zones under that. If I were then to burst from there to Bluebox, the Keystone domain name would be the one that I was assigned back at Dreamhost.<br>
