[topicmapmail] PSIs - alternatives

Alexander,

Well, I think it is time to simply admit that having unique persistent 
identifiers presumes that everyone would use the same identifiers for 
the same subjects.

If that were true, then we would not have the problems integrating 
information that we do now. Reinventing the notion of a universal name 
set that everyone will use, with or without repositories, is simply a 
non-starter. Even if it is prefaced with the "sacred" prefix http://.

What we can do is encourage people to write PSIs and treat PSIs as 
subject proxies and merge different PSIs that in at least the merging 
author's view, represent the same subject. I cannot really imagine US 
authors using PSIs coined by the Taliban nor vice versa, and both (at 
least in my opinion) are equally legitimate.

Rather than chasing the chimera of a universal language or naming 
convention, why not simply embrace the fact that for all sorts of 
reasons, some good, some less so, depending on where you stand, people 
want to identify their subjects differently?

PSI's have a vital role to play even in a diversity senario because they 
are a public notice that here is how I identify subject X. So if you use 
some other identifier and merge it with mine, then you can find that 
subject in either your materials or mine.

Allows all the "wild dogs" ;-) and others to do what is just in their 
own eyes and still enables integration of diverse information resources.

Hope you are having a great day!

Patrick
