B3Wiki Schema

Domain

A knowledge base about the Hammond organ — its history, technology (tonewheels, drawbars, vibrato/chorus, percussion), the Leslie speaker ecosystem, key players (Laurens Hammond, Donald Leslie), iconic artists (Jimmy Smith and the jazz organ tradition), and the modern clonewheel era. English-language wiki.

Purpose: first-hand compiled knowledge over vendor docs; one page = one clear lesson or entity. Sources are ingested verbatim into raw/ and synthesized here.

Conventions

File names: lowercase, hyphens, no spaces (e.g., tonewheel-generator.md)
Every wiki page starts with YAML frontmatter (see below)
Use [[wikilinks]] to link between pages (minimum 2 outbound links per page)
When updating a page, always bump the updated date
Every new page must be added to index.md under the correct section
Every action must be appended to log.md
Provenance markers: on pages synthesizing 3+ sources, append ^[raw/articles/source-file.md] to paragraphs whose claims trace to a specific source. Optional on single-source pages.

Page Thresholds

Create a page when an entity/concept appears in 2+ sources OR is central to one source
Add to existing page when a source mentions something already covered
DON'T create a page for passing mentions
Split a page when it exceeds ~200 lines
Archive superseded pages to _archive/ and remove from index

Entity Pages

Entities live in entities/ subfolders by kind:

entities/instruments/ — organs, speakers, clonewheels (Korg CX-3, Roland VK series, Nord C2D…)
entities/players/ — organists only (people who play the Hammond on stage/records)
entities/manufacturers/ — companies (Hammond, Suzuki, Korg, Roland, Clavia…)
entities/bands/ — organ-led bands (JTQ, The Link Quartet, Parlor Greens…)
entities/albums/ — landmark albums and recordings
entities/labels/ — record labels dedicated to organ music (Hammondbeat, Scufflin'…)
entities/people/ — non-player humans: inventors, engineers, producers

Optional date fields (anniversary tracking)

people/players frontmatter: born: YYYY-MM-DD, died: YYYY-MM-DD
albums/instruments frontmatter: released: YYYY-MM-DD (year-only allowed: released: 1971)
bands frontmatter: founded: YYYY
Add only when source-supported; also mention the date in prose.

One page per notable entity (person, company, instrument model, product line). Overview, key facts/dates, relationships via [[wikilinks]], sources.

Newer sources generally supersede older ones
Genuinely contradictory claims: note both with dates and sources
Mark contradictions: in frontmatter and flag for review
