This isn't really "next generation" and it also isn't a "parser."
Applications such as this have existed for many years. Examples include
GroveMinder, Astoria, Texcel Information Manager, etc. These things aren't
parsers because they don't parse anything. In ISO terminology they are
"grove providers." In Web terminology they are persistent DOM
implementations.

If you design your system correctly then you can just send the user a
table of contents that *represents* the large data set, or a page of data
at a time.

This thread is confusing to me because people keep sliding back and forth
between 

 a) relational storage,
 b) human-created document archiving,
 c) human-requested query results,

as if there were no architectural difference. But there is.
