[PowerLoom Forum] Commercial use

[Hans Chalupsky]

PowerLoom licensing is very liberal where you can pick from three
alternative licensing schemes.  One of the available licenses is
Mozilla MPL 1.1 which should satisfy most people who want to use it in
a commercial setting (see top of
http://www.isi.edu/isd/LOOM/PowerLoom/download.html).

Nothing much has happened on the persistence code, since the funding
we were hoping to get for this disappeared in the general economic
downturn.  There are some new funding developments that make me
hopeful that we'll be able to pick this up again fairly soon, but we
won't know until the fat lady sings.

For many situations it might be sufficient to use PowerLoom's RDBMS
backend to get the persistence you need.  You often have a large
amount of data that's flat and can be represented in a relatively
small number of tables.  In that case, it's easy to offload that
portion onto an RDBMS such as MySQL or Oracle and then query it
relative to an ontology and other more complex but smaller scale
knowledge loaded into PowerLoom from a file. I do that fairly often
myself.
