v1.6.0 β four axes, and a public data wave
18 September 2026 Β· Nabu news
Version 1.6.0 closes the classification arc that began with a survey
of twenty-one prior classification schemes and ended, three phases
later, with a working fourth axis. Beside when, where and in
what language variety, every document in the library can now answer
what kind of text it is β across
1,953,835 classified documents
(85% of the kind-eligible
library, as of 19 September 2026),
21 class families, every family
attested. The tree is optionally deep β literary holds its poetry,
narrative, drama and their siblings; any prefix matches its whole
family β and every fold preserves the upstream label verbatim beside
it. The three older layers now share one
Layers page: one doctrine
(extracted, never guessed; honesty buckets counted, never hidden),
three sections, filters that stack in one query.
The release also ships the machinery a living library needs when an upstream cleans house: when PerseusDL deliberately retired ninety-six superseded Cicero editions, the libraryβs withdrawal alarm said so β loudly, correctly, and forever. A reviewed upstream curation event can now be accepted: the alarm quiets to a dated note and re-arms the moment shedding grows past the accepted level. The health board is fully green for the first time in a week, with nothing swept under a rug to get there.
And the derived layers are going public. The nabu-data sister repository is receiving its largest wave since it opened: the complete kind-classifications table (the fourth axis, per-document, with every upstream label in-band), the cuneiform sense glosses sidecar (Wiktionaryβs Sumerian, Akkadian and Hittite lanes, under their own share-alike license beside the CC-BY sign table), and re-derivations of the standing catalog-wide datasets β lect assignments, document dates, places β from a catalog two million documents richer than their last cut. Each dataset carries its full derivation provenance, as always: the exact producing code version, the input identities, and a recipe that makes the build repeatable end to end.
