Re: A standard approach to glueing together reusable XML fra


scott parnell
I like what I see in TeraText, from their web site, but none of the 
situations of which I am aware can afford to treat the data elements, or 
XML data items, as text only. Every one of these applications has cause to 
use relations between normal forms of the data elements, and to do advanced 
indexing on various data types not just text, such as dates and date 
ranges, numerical process results (averages, means, distributions, etc), 
scientific enumerations and so on.

Gov't docs are often like that - they are heavily laden with text or prose, 
but also have significant valuations in other data types including math 
equations with all sorts of notation formats or other readings such as 
pollution indexes from the EPA, or farm crop estimates vs. harvests by crop 
by month by county by year, or rainfall vs. temperature over time for each 
day by gps coordinate areas, etc. etc.

On top of which it seems typical to gov't paper processes that rule-based 
activities or rule based processes prevail, are interdependent or subject 
to relations of various levels of complexity ranging from simple to quite 
complex, and are dynamic or subject to seemingly random changes, sometimes 
quite frequent changes.

I can do rule based stuff like Prolog integration with a relational dbms, 
but I know of no Prolog-XML development path, or other rule based XML path 
that offers normal form relations.

Think Library of Congress, and then consider a researcher wanting to 
correlate results across a variety of sciences, seeking both text and 
mathematical results from all available statistical items (published 
studies) as well as other results, such as a comparision / contrast of 
leading researcher articles in text form, but only the relevant sections & 
footnotes or references. For any given area of inquiry, over any time 
frame, any areas of science, etc.etc.etc. Kind of a Trantor University 
(Asimov) thing, I know, but as an end result my sense is that such is 
doable, and integration into a larger knowledge base should be a factor in 
every XML system out there, at least every gov't system, if you ask me.

In other words, the TeraText approach does not seem to support relations 
between normal forms, and so seems to have a self imposed design limit that 
I, personally, find short of desirable. It is not just about massive data 
handling, but also about being able to do things with that data after it 
has been captured and has existed for some time, things that support 
requirements that are not yet known. In my opinion. Only normal forms and 
relational theory or the relational model (RM) offer this capability, in my 
opinion.

Thanks for your response.
