Two DCP test corpora have licences written for software. libdcp is GPL-2.0, with an SMPTE BSD-style licence for portions. ClairMeta_Data (about 1.1 GB of DCP, MXF and XML test packages) carries a BSD-style YMAGIS licence. Neither says whether its licence covers the test essences and packages, so treat the test media's reuse terms as unclear. Curator qualifications: Licence texts read 2026-10-22; no test file downloaded. Whether repository licences cover the test media is not stated (hold). Limitations: Licence texts read 2026-10-22; no test file downloaded. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
