Re: XML format for statistical data and analysis?



Thanks for your detailed response. I am trying to find a way to represent a mound of data from discrete event simulation replications (Monte Carlo on a detailed model) while keeping the data tables related to each other. XML, done properly, can maintain those relationships. And, as you said, XML is also an easy way to keep model assumptions, optimization parameters, and other notes with the original data without interfering with its analysis.

I had seen a reference to XLMA in which SAS had been involved, but that seems to have died. I don't use R (yet!), so I was hoping that commercial statistical packages could read XML and create multiple tables.

Your reference to esql in cocoon looked useful, because some of the data is in a MySQL data base. I'll have to check in detail.

What XML Schema do you use? I realize that the database constraints can be represented, but am unsure where the rest of the format originates.
