PSPP and MDD files

[Dave Trollope]

Hi,

I've been using PSPP for a while, but am relatively new to SPSS as a
whole and I am wondering if it can generate a .mdd file from the .sav file?

I know IBM's mrStudio has a script CreateMddFromSav.mrs and I'm
wondering if PSPP has an equivalent?

Cheers

Dave

This is the first I've heard of this format. PSPP doesn't currently
support it.

What is an MDD file? Is it the format described here?

Hi,

Unfortunately no, its not listed there. Its an XML version of the .sav
meta data. I think its the SPSS data dictionary in XML form.

This site also relates it to a DDF file:

I can't find a better reference.

Cheers

Can you provide a sample MDD file, or point to one?

I pushed this feature to the PSPP repository, so you should be able to
build a version that includes it.
