How Rasin makes historical claims traceable.

Rasin documents the path from source material to search result: OCR, translation, metadata, citations, graph links, AI answers, and review. The goal is simple: every claim can be traced back to the evidence behind it.

01Why

The history people most need is the history that is hardest to hold.

The Haitian Revolution is one of the most consequential events of the modern world: a self-emancipated nation founded by formerly enslaved people, a constitutional rupture the Atlantic world spent two centuries trying to contain. Its archive is correspondingly difficult: scattered across empires, written in several languages, and told from positions that do not agree on what happened.

For most readers, that archive is unreachable. Researchers who can read it spend years assembling fragments by hand. Rasin makes that assembly visible, so a curious reader, a graduate student, or a descendant working on family history can move through the same corpus with the disagreements and absences shown plainly.

We are not building a chatbot for history. We are building an archive that helps readers compare sources, with citations, uncertainty, and disagreement kept visible.

02Principles

Five commitments we hold ourselves to.

Source-first

No claim is repeated without a path back to a primary or scholarly document. The text you see is always traceable.

Multi-perspective

Colonial, Haitian, diplomatic, primary, and scholarly voices are tagged distinctly. We do not flatten them into a single narrator.

Show your work

AI summaries should list the passages they drew on. Citation status and disagreement labels appear only where supporting data exists.

Accountable

Corrections are reviewed without erasing the original record. Public errata tracking is still being built, so this page does not publish counts yet.

Limits made visible

OCR errors, archival silences, language gaps, and model uncertainty are surfaced as part of the record, not hidden behind polish.

Traceability checks

What traceability means in Rasin.

Corpus breadth

Source pluralism

Rasin draws from a growing corpus across Haiti, France, the U.S., and the Caribbean. Source-authority metadata is displayed where available, and coverage is being expanded across the live source registry.

Perspective warning

Bias is surfaced before it misleads

Perspective tags follow documents into search results, claims, and graph links. When one perspective dominates retrieval, the interface warns the reader instead of pretending the corpus is neutral.

Citation check

Claims are verified against passages

Rasin pairs generated answers with citations and runs support checks so a quoted passage has to actually ground the factual claim it is attached to.

Model governance

Model routing is explicit

OCR, embeddings, reranking, citation verification, entity extraction, and answer synthesis are tracked as separate model roles. For each role, Rasin documents the provider, retention boundary, and review status.

03Perspective system

A color key for source perspective.

Rasin uses color to help readers recognize the kind of source behind a result before they read the claim. When perspective tags are available, the same color follows that source through search, people, events, documents, and graph links.

The colors are context cues, not rankings. They distinguish colonial administration, Haitian institutions and vernacular traditions, foreign diplomacy, scholarship, and primary records so readers can compare evidence with more care.

Colonial

Colonial and French state

Blue marks royal ordinances, planter correspondence, colonial newspapers, and administrative reports produced inside colonial or French state systems.

Haitian

Haitian state, oral, vernacular

Gold marks constitutions, presidential papers, Kreyòl testimony, Haitian sacred practice, oral tradition, and Haitian intellectual work.

Diplomatic

Foreign-state diplomatic

Green-gray marks U.S., British, Spanish, and other diplomatic dispatches, helping readers separate outside observation from Haitian self-description.

Scholarly

Scholarship and criticism

Purple marks historical, philological, cultural, and digital humanities scholarship, presented as interpretation rather than the source record itself.

Primary

Witness and record

Deep green marks first-person testimony, legal records, manifests, maps, and period documents kept close to their original context.

04Source pipeline

How sources become traceable claims.

A document enters Rasin through a staged pipeline. Some steps are automated, some are manual, and launch-facing claims should remain reviewable before they are presented as settled.

01

Acquire

Source documents are digitized or imported from partner archives and public collections with original URLs and provenance metadata retained.

02

Transcribe

OCR and period-aware extraction convert scans into text, while uncertain glyphs, damaged pages, and language issues remain flagged.

03

Tag

People, places, dates, claims, source types, and perspectives are structured for review and downstream retrieval.

04

Cross-reference

Claims are linked to existing entities and related passages. Conflicts are surfaced, not silenced.

05

Publish

Reviewed material can go live with citation paths and review status. Persistent identifiers and public version metadata remain launch standards until product records back them.

Processing flow
Pipeline: Documents → OCR → Chunks → Embeddings → Graph → Search → Answer
Cross-lingual retrieval
Cross-lingual: EN, FR, KR queries converge nearby in vector space
Hybrid retrieval and citation check
Retrieval: Query fans out to Vector search, BM25, Graph traversal → RRF → Reranker → LLM → NLI → Answer
05Claim verification

Three statuses, one rule: never a single voice.

Claim status is an editorial standard, not an automatic verdict. A claim should be labeled only when the supporting passages and review context are visible enough to justify that label.

Attested

Independent sources support the claim, and the passages doing that work are visible.

Contested

Sources disagree, often along perspective lines. Rasin should display the positions rather than choose a winner for the reader.

Disputed

A named scholar or source tradition challenges the claim. The challenge should be linked, and the original record preserved.

Publication standard

No illustrative claim is shown until it exists in the product.

Worked examples should come from the live knowledge graph or stay out of the launch page. Until then, this section describes the review rule rather than inventing a case study.

Source passage

The claim stays attached to the document, passage, and source metadata that support it.

Review status

Attested, contested, and disputed labels are used only when the evidence is visible enough to review.

Hold back

If support is missing or the graph disagrees with the page copy, the claim is removed or marked as unfinished.

06AI and editorial review

What the model does, and what it does not.

Model boundaries

Rasin uses language models for transcription assistance, entity extraction, retrieval support, and grounded summary synthesis.

The model never invents a source, never decides a claim status, and never resolves a contested historical question by itself.

Where the corpus is silent, the page stays silent. Model roles and evaluation notes are documented for review where available; public release notes are still in build-out.

Signed review

Reviewed pages will name the editors who signed off. Names are not decorative; they are accountable parties.

We are forming an editorial board with domain knowledge in Haitian and Caribbean history, African diasporic religions and belief systems, Atlantic legal history, linguistics, and digital humanities.

07Errata and citation

Corrections should be part of the record.

The public correction workflow is still being built. Today, corrections and contested claims are reviewed manually; the future goal is a visible record that preserves the original reading, reason for change, and reviewer who accepted it.

We will publish public counts and versioned citation metadata only after that workflow is live.

Correction workflow

Public errata tracking is not live yet.

No errata counts are shown here until they come from the product itself. This page should document the standard we are building toward, not imply completed review volume.

Flag a passage

For now, send corrections, contested readings, missing citations, or source questions directly to the team.

Found something we got wrong? Tell us.

We review every flag directly while the public errata layer is being built. Scholarship is a conversation; Rasin is a way of holding that conversation legibly.
