R help - Feb 2001 - PMML- Predictive model markup language

Hi all, 

I caught a passing reference to PMML on the WEKA list (I think) .. an XML 
way of communicating 'data mining models'.  I am of the opinion that XML
is a 'good thing' and I would for instance like to see a standard XML
way
of communicating the content and context of datasets (eg of timeseries) 
but it has been a long day and my internet connection is slow and so I 
have not worked through the slideshow at
http://www.dmg.org/
but wonder if anyone else has examined PMML and can give an opinion as to 
whether this (PMML) is worthwhile opening up as a discussion thread.

If not, I will look at it in a day or so when I can get some energy and 
time and report back.

thanks

John Aitchison

I looked at it in the past, and it is quite intriguing -- it's similar
to some work people are doing on literate data/statistical analysis
(round-trip).  However, it's more specific and focused, and I'm not
sure that I agree with how they are communicating models (but that's a
small disagreement on specific implementations, not on the need for
this type of communication system for data analysis).

best,
