Citation system

Many. This issue is a candidate list, not a change to any one record.

What is wrong or missing?

The registry holds twelve works and ten citation systems. The ROADMAP plans to "grow the
registry with more canonical examples across theology, classics, philosophy, law, and other
citation traditions."

This issue archives a survey of candidates for that growth. It replaces two working documents
that were sitting untracked in this repository and are now deleted. It exists so the material
is reviewable and linkable rather than sitting in someone's working tree.

Read the tables as leads, not as findings. Both source documents were LLM-generated, and
their sourcing is uneven:

• The first document cites a ZDF television fact-check PDF as its source for the Kant corpus
  URL scheme, and a Reddit thread for CBETA. Those are not usable.
• The second document is better sourced and its links were mostly checkable.
• Nothing in either was verified before it was written down.

Verification since has already overturned two of the survey's headline recommendations, both
of which looked obviously right on paper:

• Its top-rated find, Perseus/Scaife CTS, cannot serve Stephanus or Bekker locators. The
  edition Scaife hosts is cited by book and chapter, and Scaife silently returns the last
  chunk of a work for any passage it cannot parse. A resolver built from the survey's advice
  would have sent every Republic reference to Book X, at HTTP 200.
• Its "A+" for the Wittgenstein Archives at Bergen is a rating of the archive, not of its
  fitness as a resolver. Bergen addresses Nachlass sigla, never published propositions or
  sections.

That is the standing lesson for everything below: a resolver returning HTTP 200 is not
evidence. Always test an invalid locator as a control.

Suggested correction or new value

Work the candidates through the child issues. Order follows the survey's three waves.

• data: do not add Scaife CTS resolvers to the Republic and the Nicomachean Ethics #22 — Perseus/Scaife CTS for the Republic and the Nicomachean Ethics — verified, negative
• data: add the Qurʾān as a work with a sura-verse citation system #23 — the Qurʾān as a work with a sura-verse system
• data: the Wittgenstein Archives cannot resolve Tractatus propositions or Investigations sections #24 — Wittgenstein Archives Bergen for the Tractatus and the Investigations — verified, negative
• data: second-wave work candidates with established citation systems #25 — second-wave candidates: Dante, Aquinas, the Digest, Shakespeare, Nietzsche, Kant, Hume
• data: audit the resolver targets on the twelve registered works #26 — audit the resolver targets on the twelve registered works
• data: seed alternative_labels on works/*.yaml #27 — seed alternative_labels on works/*.yaml

Not yet opened as issues. First-wave reference spaces from the second document, which it
describes as near-automatically importable because a deterministic relation already exists
between canonical locator and online passage: SHEBANQ/ETCBC for the Hebrew Bible, Sefaria for
rabbinic literature, Chinese Text Project beyond the two works already using it, and the SAT
Daizōkyō database for the Taishō canon. The survey's own closing suggestion was to build a
harvest table of 100–300 work candidates with discipline, citation system, authority, resolver,
example reference and example resolved URL. That remains a reasonable next step, and it is
still unstarted.

Third wave, for discovery only rather than as resolvers: GRETIL and SARIT for Indic material.

Evidence and sources

Both tables are reproduced as written, with only the column headers and the discipline names
translated. Cell contents are the survey's own words and are unverified. The class column is
the survey's judgement:

• A — a formal query interface or a documented machine-addressable passage resolution
  (DTS, CTS, SPARQL, REST).
• B — deterministic URL paths or anchors, addressable in a browser, reconstructable but
  not formally specified.
• C — a scholarly edition addressable only at work or volume level.

The second document draws an explicit distinction worth keeping: A does not mean "a good
scholarly website." It means machine-addressable passage resolution was found or is
documented. B means the work and its internal citation structure are well established and
online, but the HTTP resolver is less formalised.

It also separates two things the registry should keep separate, and which TextRefs already
models separately: the scholarly standing of the canonical reference versus the governance
of the resolver provider. SuttaCentral is its example — technically excellent, and
explicit that it has no institutional affiliation.

Rights or licence note

Nothing here enters the registry as data. Licence and access must be established per resolver
when each candidate is actually implemented; several are academic sites with no explicit
licence, which is a license_url:-only case at best.

Second-wave verification pass done (#25), 2026-08-25. Updating the survey's scorecard, since this issue exists to keep the record honest.

The standing lesson holds, but it now cuts both ways. The survey was wrong on two headline A+ ratings, as this issue already records. It was also too pessimistic on three rows — two of the blockers #25 recorded no longer exist.

Running tally of survey claims actually checked:

Survey claim	Verified result
Perseus/Scaife CTS — A+	Wrong. Cannot serve Stephanus or Bekker; returns the wrong passage at HTTP 200 (#22)
Wittgenstein Archives Bergen — A+	Wrong as a resolver. Nachlass sigla only (#24)
Corpus Coranicum — A+	Holds, but only on /print; /commentary accepts 999:999 (#23)
Folger Shakespeare — A−	Understated. Resolves act/scene/line directly; no FTLN concordance needed (#33)
Hume Texts Online — A	Holds. Real 404s on bad input, the cleanest controls of the seven (#34)
Roman Law Library — B+	Holds. Anchors are the citation itself, 613 in Digest book 41 (#35)
Nietzsche Source eKGWB — A	Holds, and its hash-URI blocker is obsolete — the path form is server-validated (#36)
Dartmouth / Princeton Dante — B+	Split. Princeton resolves a verse; Dante Lab is canto-only and its HTTPS cert does not match its hostname (#37)
Corpus Thomisticum — B+	Overstated. Irregular page chunks plus opaque anchors; article-level addressing is unreachable

One row could not be checked: the Kant-Korpus host resolves but does not accept TCP connections, from either curl or Chrome. Not recorded as dead on one day's evidence.

Two findings worth carrying forward as method, alongside the "HTTP 200 is not evidence" rule this issue already states:

1. Check the certificate, not just the response. Dante Lab answers fine over plaintext HTTP; its TLS cert is CN=*.herokuapp.com and does not match dantelab.dartmouth.edu. Same disqualifier as wittgensteinsource.org in data: the Wittgenstein Archives cannot resolve Tractatus propositions or Investigations sections #24, and invisible if you only look at status codes.
2. A single-page app may ignore a scripted hash change. Driving Nietzsche Source by setting location.hash in a loop returns the same page every time while appearing to confirm several sigla. Use a full navigation per identifier.

Child issue list, updated:

• data: do not add Scaife CTS resolvers to the Republic and the Nicomachean Ethics #22 — Perseus/Scaife for the Republic and the Nicomachean Ethics — verified, negative (recorded in the data, closed)
• data: add the Qurʾān as a work with a sura-verse citation system #23 — the Qurʾān — draft PR feat(works): add the Qurʾān with a sura-verse citation system #32, blocked on compile: references_range hardcodes the locator separator, so a colon-cited system cannot use it textrefs.org#94
• data: the Wittgenstein Archives cannot resolve Tractatus propositions or Investigations sections #24 — Wittgenstein Archives Bergen — verified, negative (recorded in the data, closed)
• data: second-wave work candidates with established citation systems #25 — second-wave candidates — verified; five split out below, two deferred
• data: audit the resolver targets on the twelve registered works #26 — resolver-target audit — Wikisource half merged, rest open
• data: seed alternative_labels on works/*.yaml #27 — seed alternative_labels — merged
• data: add the Shakespeare plays with act-scene-line, resolved by Folger #33 — Shakespeare
• data: add Hume's Treatise and first Enquiry, resolved by Hume Texts Online #34 — Hume
• data: add Justinian's Digest, resolved by the Roman Law Library #35 — Digest
• data: add Nietzsche's works, resolved by Nietzsche Source eKGWB #36 — Nietzsche
• data: add Dante's Divina Commedia, resolved by the Princeton Dante Project #37 — Dante

Still unopened, from the first wave in the second source document: SHEBANQ/ETCBC, Sefaria beyond the Tanakh, Chinese Text Project beyond the two works already using it, and SAT Daizōkyō.
