If you want a file format for R datasets which describe their
own metadata, it might be worth thinking about defining it in
This probably goes a long way beyong Peter's suggestion, but
presumably it could be done in the same way, by adding a header
to the top of a data file. It does leave open the possibility
that other statistical packages will be able to read the data
and extract any meta data (storage type, variable labels, value
labels, ...) they want to use.
I have been thinking for a long time that it would be nice if
statistical packages could exchange datasets using a common
file format and (unless I have drastically misunderstood) XML
seems the way to go.
