This product is distributed under two licenses, applying to different artifacts.

The Vietnamese dictionary database is NOT covered by the Apache License. It is
derived from Wiktionary text — word forms and edited excerpts of their
definitions — and remains under the licence that text carries, CC BY-SA 4.0:

  Affected artifacts:  data/noitu.db  (and data/viwiktionary-latest-pages-articles.xml.bz2,
                       the Wikimedia dump it is built from)
  License text:        data/LICENSE
  Attribution and
  list of changes:     data/ATTRIBUTION.md
  Original work:       Wiktionary tiếng Việt (https://vi.wiktionary.org/), by its contributors
  Source:              https://dumps.wikimedia.org/viwiktionary/, the monthly
                       pages-articles dump; fetched fresh for each build, identified
                       by the SHA-256 recorded in the database's meta table

CC BY-SA 4.0 is a share-alike license. Any distribution of the derived database
-- including inside a container image or other packaged build -- must carry the
same license, this attribution, and the record of modifications.

The two regimes are kept on separate artifacts deliberately: the database is
loaded at runtime from a file and is never embedded, compiled, or linked into
the Go binary.

Neither the source dump nor the derived database is committed to version
control. Both are build artifacts produced by `make fetch-dict` and `make dict`.
