[xtm-wg] Portal Markup Language and Topic Map Template

["Scott Tsao" <scott.tsao@boeing.com>]

I recently posted the following question in the 
topicmapmail@infoloom.com mailing list:

"I am looking for comments regarding the differences between using 
DTD (i.e., PML) and topic map template for exchange of information 
maintained by a typical portal tool, e.g., metadata about information 
objects, users, groups, access controls, subscriptions, and 
notifications.  It seems to me that most (if not all) of these portal 
related metadata can be "standardized" in terms of topic map 
templates that are declarative in nature and can be reused and shared 
by portals from different vendors.  As a result, the mechanics for 
sharing and exchange portal information can be accomplished in the 
form of the standard topic map interchange format (be it ISO-based 
Varlink or XTM-based XLink).  I wonder if the differences between
these two approaches might be architecturally significant, e.g., 
flexibility, extensibility, portability, etc."

Since I have not heard any responses yet, I thought I might post the 
same question in this XTM-WG forum as well.  Again, anyone care to 
comment?  (BTW: I won't be offended if you tell me that I am asking a 
stupid question :-)

Thanks,
