   RE: [xml-dev] Registered Namespace prefixes

[ Lists Home | Date Index | Thread Index ]

It would seem to me that such a registry should 
be part of the metadata of a site (see Tim Bray's 
recent contribution to TAG on sites) and not a 
separate database as such.  That way interoperation 
falls out of the standard web architecture and 
possibly, the semantic web.   I contend that such 
a registry, particularly for government systems, 
will require related assertions with regards to 
the responsibilities of the registrar. 


From: Chiusano Joseph [mailto:chiusano_joseph@bah.com]

There is still the trouble associated to the centralized
aspect of such a database, but that can be minimized by sharing 
openly the content of the database and allowing free mirroring of
the information herein.

That may actually be useful, 

Absolutely. I am not a proponent (and never have been) of the "single
central authority" approach to data management (or whatever term you'd
like to use).  I can definitively tell you that the Federal government
"mindset" (at least in my opinion and experience) is that a series of
such databases (registries for our discussion purposes) that are
interoperable to the point where they can exchange information (perhaps
for replication purposes), and query one another in a uniform manner is
a *very* good thing.  For example, government agency X could have its
own registry that is used to maintain its own XML artifacts;
additionally, it is able to communicate (directly or through a gateway)
with the registries of other government agencies (assuming proper
security policies and mechanisms, etc.).  Topology could be peer-to-peer
topology, hierarchical, hub-and-spoke, or some other topology.
