Hi nusenu,

I've been going through old mail, and on 2015-04-16 you asked about
about a license (see above).

Just added a LICENSE file - can't hurt (standard BSD 3-clause).

If you're still by any chance collating (ha) and/or want to talk about
schema design for descriptors (I personally would not lose hope for
RDBMSes for large datasets - not until one gets into *actually* big
data - say, terabytes at least, or more - but of course it gets
nuanced real fast).
