<br>
That page lists 19 data namespaces, which shows that there is<br>
significant user support for CTS=2E<br>
<br>
&gt; The registration process will be an interesting topic to discuss=2E I=
<br>
&gt; understand your comment in a way that leads to a central authority=2E=
<br>
&gt; My abstract idea is an open registration, hosted *somewhere* that<br>
&gt; works purely on FCFS without an authority that decides who may or may=
<br>
&gt; not register a new namespace as long as it does not collide=2E With t=
he<br>
&gt; option to choose your registry similiar to how you can choose your DN=
S<br>
&gt; provider=2E Choosing your registry would also limit the harm that cou=
ld<br>
&gt; arise from misuse=2E<br>
<br>
We definitely need a registration system in order to ensure URN<br>
uniqueness, which is a requirement of URN registration -- organizations<br=
>
need to know what possible URNs they are allowed to create=2E  If we get<b=
r>
an IANA registry established under "FCFS" policy, then there is no<br>
restriction regarding who may register which new data namespace=2E  Also,<=
br>
registration with IANA would implicitly put each data namespace owner on<b=
r>
notice that they had to adhere to the registered CTS syntax=2E<br>
<br>
And I do see it as a problem that we need to ensure the users of CTS<br>
conform to the proper syntax=2E<br>
<br>
It would be straightforward to establish an IANA registry=2E  It would<br>
take a great deal of work to establish a system with multiple<br>
registrars=2E  And it might not be possible to recruit multiple<br>
registrars, whereas the IESG can direct IANA to operate a registry=2E<br>
<br>
In regard to trusting IANA to carry out its duties correctly =2E=2E=2E If =
IANA<br>
doesn't function well, the Internet has many more problems than just<br>
CTS=2E<br>
<br>
Although if you see a way to do decentralized allocation of data<br>
namespaces, I would like to see the details=2E<br>
<br>
&gt; Another issue with a central registry might come from the domain=2E I=
t<br>
&gt; seems that the need to register namespaces is not very strong in the<=
br>
&gt; humanities :) =2E The problem with unregistered URNs would escalate<b=
r>
&gt; further if new data sets appear without registration=2E A decentralis=
ed<br>
&gt; registry would eliminate this problem because then it is the users<br=
>
&gt; responsibility=2E<br>
<br>
I don't think there is anything we can do about people creating CTS URNs<b=
r>
without proper registration, all we can do is create clear rules that<br>
allow us to say that they are nonconforming=2E<br>
<br>
&gt; And finally I don't see, how a central registry could prevent<br>
&gt; "namespace brokers" from registering and selling namespaces to<br>
&gt; academic institutions=2E In a decentralised registry, this business<b=
r>
&gt; model cannot appear=2E<br>
<br>
I think the situation is similar to domain names, in that there are many<b=
r>
alternative forms of the name of an institution or project, and it is<br>
unlikely that brokers will have speculatively registered all of them=2E<br=
