In the end i have a nicely organized hdf5 file, that i can use to do data mining.

Hi, Nico.
Not a direct answer to your question, but have a look at the
Bioconductor package GEOmetadb. (There is also an online version.)
We have parsed all of GEO metadata into a SQLite database and made it
available within R. However, the SQLite database can be used
standalone and python has built in support for SQLite, as of late.

Also, as for the data, if you are inclined to use R for anything (or
rpy2), the GEOquery package can download and parse all the record
types in GEO into objects within R and the number of tools for data
analysis of microarray data in R/Bioconductor is enormous.

Sorry for the advertisement-like email....
