According to http://stackoverflow.com/questions/4263395/any-one-tried-mongodb-on-google-app-engine "You can't run MongoDB on GAE. You need to use the Google datastore." Thus you might want to checkout Google datastore, which I know nothing about. > I want to store data from here: > > http://physics.nist.gov/PhysRefData/DFTdata/Tables/ptable.html > > and I can of course store it as some hdf5 files, that are essentially > just binary numpy arrays.

It sounds like maybe all you need is a key:value store? -- William > > Ondrej > > -- > To post to this group, send an email to [email protected] > To unsubscribe from this group, send an email to > [email protected] > For more options, visit this group at > http://groups.google.com/group/sage-devel > URL: http://www.sagemath.org > -- William Stein Professor of Mathematics University of Washington http://wstein.org -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
