Commercial licensing option for the DCML corpora?

[oracle9i88]

Hello,

Thank you for the DCML corpora — the encodings and harmony annotations are
an outstanding resource, and the annotation standard is a real contribution.

I'm writing to ask whether a commercial licensing option exists, or could be
arranged, alongside the CC BY-NC-SA release.

Our use case, stated plainly:

• We are building a small symbolic music generation model for classical
  piano and small chamber ensembles, with a strict provenance chain:
  every training item is tracked with its source, license, and file hash.
• We would use your scores as training data only. We would not
  redistribute the corpora, the scores, or the annotations in any form.
• Our outputs are original compositions rendered to audio; we do not
  reproduce or distribute the source works.
• We would of course cite the data reports (Hentschel et al.) in any
  publication or documentation.

We are a very small operation, so this is not a large commercial deployment —
but we would rather ask and be correct than assume and be wrong.

Would a commercial or research-to-commercial license be possible? If there
are conditions (attribution, fee, reporting, restrictions on redistribution),
we're glad to work within them.

Thank you for considering this.
